HAL Is Evolving

Halogen

What's New with HAL and Halogen 5.0?

Introduction

HAL is more than just another DSP drag-and-drop system. It has revolutionized system design and installation.

HAL is an expert in room combining, paging and distributed audio systems. This groundbreaking architecture is dimensions beyond any solution in any industry. HAL easily guides even novice users through what used to be complex tasks in just minutes. No intricate matrix mixing or presets are required for room combining and paging. No virtual wiring is required to distribute pages and background music to multiple, even hundreds of zones.

Seamlessly interface HAL to your application with web controls and/or a broad variety of peripheral devices including smart Digital Remotes, Remote Audio Devices (RADs), portable or rack automixers, audio I/O and logic expansion devices, wall sensors, ambient sensing mics, small remote amplifiers, and an advanced Paging Station. Control HAL functions from a web browser in a smartphone or tablet.

In addition, the HAL Multiprocessor and Halogen™ software check the status, location, CAT 5 wiring integrity, and that audio is flowing in all peripheral devices, so you know your system is properly connected and ready to go.

Halogen software includes Ethernet control support for third-party control systems such as AMX®, Crestron® and Stardraw Control™, including well-documented examples. Standard TCP/IP set and get ASCII text messages control levels, selectors, presets and toggle software actions. Since the same Halogen software code runs on both Windows® and within HAL hardware, third-party control developers can test all their code using only the Halogen Windows software. Use only software for complete system design and validation. Buy the hardware only when the install date arrives. Standard TCP/IP set and get ASCII text messages control levels, selectors, presets and toggle software actions.

HAL Hardware

Four HAL Multiprocessors provide various audio I/O and control options for large, medium and small installations.

HAL1x

HAL1x

HAL1x supports 16 in x 16 out audio, which may be increased up to 512 in x 512 out by adding up to 32 daisy-chained Expanders to a single HAL1x. Add a few to hundreds of more mic inputs with AM Automixers.

All Digital Remotes

Ethernet, RAD and DR Cable Lengths

CAT5e cable lengths

The maximum length for CAT 5e cable between ethernet devices is 100 meters.

Shielded CAT 5e between a HAL or EXP and a RAD (carrying 4 channels of digital audio) can run up to 150 meters.

Shielded CAT 5e between a HAL or EXP and a DR (carrying control information) can run up to 300 meters.

It is possible to extend these lengths by increasing distance between the HAL and Expanders. Up to 32 Expanders can daisy-chain from a single HAL, and each can be up to 100 meters apart. For greater distance, off-the shelf Gbit Ethernet media converters are supported. Multimode fiber can run up to 2 kilometers, and singlemode fiber can run up to 12 kilometers.

Halogen Software

Install Halogen Software 5.0.0

Click 'Run' to install. The .NET Framework 4 will be installed if it's not already on your PC, requiring additional download time.

System requirements: Computer running Microsoft Windows XP SP3 (32-bit), Vista SP1 (32 or 64-bit), Windows 7 or 8 (32 or 64-bit) with an Ethernet port.

HalogenHalogen Software Introduction

The Halogen software application is your home for designing, configuring, and controlling your HAL audio system. Halogen's easy-to-use graphical user interface simplifies the design and configuration process. With the free download, your system can be designed before any hardware is ordered!

The Halogen software manages global tasks such as discovering, connecting to, and applying configurations to HAL devices. The interface is divided into two main sections: the Hardware Workspace and the Processing Workspace.

Halogen helps with the first step, determining which of the HAL Multiprocessors is best to build your system.

Halogen Configuration Picker

Halogen Hardware Workspace

Halogen Hardware Workspace

The Hardware Workspace is where you specify, configure, and troubleshoot the physical hardware components of your audio system.

Notice that Halogen separates the hardware view from the processing view of your audio system. A key benefit of this separation is the flexibility it provides when configuring the system's various inputs and outputs. For example, suppose you have a RAD2 in your audio system. You drag the RAD2 device into the Hardware Workspace but then go to the Processing Workspace to configure the RAD2's line input and mic input. This separation of hardware from processing allows you to work with each input and output individually instead of having to work with the hardware device as a single entity. It also allows you to focus on hardware in one place and audio flow and processing in another place—simplifying your job as a result. Brilliant!

Halogen Processing Workspace

Halogen Processing Workspace

Wire together the audio processing components of your system, adding and configuring standard processing blocks such as equalizers, matrix mixers, compressors, limiters, and so on. Manage and configure control links and presets here. Halogen also provides innovative processing blocks that simplify complex paging and room combine scenarios.

As you may have noticed, the Hardware Workspace and the Processing Workspace have similar layouts. On the right is the actual workspace itself in which you create your system. Associated with each workspace is a palette of objects on the left, and at the top a toolbar specific to the workspace. To add an entity to your audio system, you drag one or more objects from the palette to the workspace.

Halogen Version History

New features in Halogen 5.0

HAL & Halogen software

  1. Added support for new DR6 – programmable touch screen LCD wired remote
  2. Added support for new EXP2x - 32x32 Dante expander for the HAL1x (see the programming Intro video)
  3. Added FIR Filter Import DSP block (Finite Impulse Response).
  4. Updated DR1 through DR5, Logic, and Relay Control Mode dialogs and moved them from the Hardware Workspace to the Processing Workspace
  5. Added LCD user interface simulation of DR1, DR2 and DR3 screens to DR Device Control Properties dialog.
  6. Added opening Halogen Startup dialog allowing creation of new, opening of existing configuration file, or connecting to Available live HAL devices.
  7. Added increment level and decrement level commands to the External Controls protocol (ASCII Text over TCP/IP).

Web Controls Updates

  1. Renamed Web Controls to Control Pages which includes both HTML web page and DR6 control pages. A single Control Page Designer dialog permits custom page designs to be applied to HAL-served web pages, DR6 screens or both.
  2. Added multiple, independent user access login to web controls and DR6 pages.
  3. Added copy & paste functionality to Web Controls page designer. Copy/paste the entire web or DR6 page including, or not including, the linked controls.
  4. Controls can now be resized – not just small, medium and large.
  5. Added a QR Code generator that can save image files (for later printing) and/or display QR Codes on screen for testing QR Code scanners on smart phones and tablets.
  6. Web Control Levels now ramp up or down when held down, rather than single increments.

Processing Workspace

  1. Update processing workspace selection & alignment behavior to include the anchor selection and alignment.

Bugs fixes in Halogen 5.0

  1. The External Control (3rd-party Ethernet) server was not responding correctly to Enabled and Label set commands.
  2. When navigating back to previously displayed pages, Web Control Levels sometimes displayed a 0% value even though their actual value was left at 100%.
  3. Web control aspect ratios were not being kept correctly through a file save operation.
  4. Not all web control pages were being optimally scaled correctly when loaded to devices.
  5. Highlighted input on the selector block was not being displayed properly upon re-connecting to a HAL.
  6. The Enable checkbox was not correctly reset when changing the DR3 Control Mode
  7. Deleting all Web pages did not always remove all controls.
  8. Using more than eighty Voice Detect blocks in a single configuration file could have caused audio distortion.
  9. The highlighted link in the All Links dialog could be scrolled out of view.
  10. The EXP3x’s Logic Outputs 2 through 8 were broken: they automatically linking to Port 1’s control after changing their Control Type in the Hardware Workspace.
  11. When logging in while already logged in, it was not redirecting to the home page.
  12. The feedback block’s default notch filter Q was displayed correctly, although the actual filter Q was wrong.
  13. Only output node number one on the PEQ Multichannel block was shown as yellow when Bypass All was enabled.
  14. The upper left number in the AEC DSP block is not entirely visible (obscured) when using more than 99 AEC blocks.

Known issues in Halogen 5.0

  1. If you place too many controls/elements on a single DR6, the display remains static when applied to a live DR6. It does nothing. (remember – less is more)
  2. Zone page Active status does not turn off when a zone is removed from a Scenario during an active page while linked to a toggle control. A save and re-open, an Apply or a re-Apply fixes this.
  3. The Pager1 Talk button cannot be overridden in Halogen like the other read-only (Logic) I/O controls.
  4. Workspace Labels are not Aligned properly.
  5. In Windows XP* the bottom meter or two in the EXP2x (Dante) dialog are not displayed at all – no segments turn on, although audio may be flowing.
  6. When a DR6 has no unsecured pages assigned and it is in single button (not tab) mode, the visible page does not clear after a Logout. Fix is to always have one unsecured page assigned – even a blank one.
  7. DR6 backlight settings do not take effect on the device until after each unit's screen is physically touched.
  8. Reordering DR6 pages while live may not update the order on the DR6 – although the software preview order appears correctly. Unplug and re-plug the DR6 to fix.
  9. When using more than one of the same Image file on a single DR6 screen, scaling the image differently creates rendering problems. Fix is to use unique names for the same image.
  10. The DR6 auto logout time is a few to several seconds longer than the displayed time. The longer the setting, the more the error in seconds.
  11. When pasting or moving blocks or wires so the wire ends align properly with block I/O nodes, sometimes the wires do not connect to the nodes. Workaround is to select the dashed-red wire end and move it off, then back on to the node.
  12. Sometimes, the on-screen GEQ sliders get stuck and stop moving, although the displayed graph and audio both update properly. We’ve been unable to reproduce this.
  13. When two Web Control Pages contain the same Toggle control that both link to a read-only control (e.g., a HAL Logic Input), clicking the toggle on one page briefly toggles the other web page’s control even though neither web control is able to change the state – even temporarily.
  14. After putting a Connected HAL’s computer to sleep, the Connected HAL remains in the In Use state for 10 to 15 minutes. Other computers on the network cannot connect. Workarounds are: Disconnect Halogen or unplug the Ethernet cable to the HAL before sleeping the computer or reboot the HAL.

*Note: This Halogen 5.0 release is the final release that will officially support Windows XP. The next release will not be tested or supported when using Windows XP.

Halogen 5.0.0 Single File Halogen Installer (418M)

This file does not require an internet connection to install Halogen.

Fixes in Halogen 4.1.1

  1. Many improvements were made to speed up opening, rendering and editing large configuration files. These also improved the speed that room presets are recalled in large configuration files.
  2. Browser autocomplete was enabled for Web Control page login, rendering security problematic.
  3. After the first login to secure Web Control pages, the home page, not the originating URL, was presented.
  4. The HAL gateway could not be deleted unless an existing IP Address on the gateway’s subnet was present.
  5. To add a new static IP Address or gateway required two clicks of the Add button.
  6. The HAL1x relay output was not toggling when driven by a preset.
  7. Changing the case of Web Control page names was causing occasional page not found errors.
  8. Wall and preset changes in very large configuration files were updating the hardware and audio quickly, but the software screen update was slow causing corrupt configuration files when saving before the screen caught up.
  9. When updating a configuration from 4.0.1 to 4.1, selector links to Paging Station Scenarios were get updated incorrectly – the number of selectors was doubling.
  10. Newly selected items on Web Controls selectors used to flicker slightly.
  11. When the Windows Firewall is not present (not installed), cryptic Halogen messages during initial installation were confusing although no problem was actually occurring.
  12. When linking many PEQ filters and a DR Level together, making adjustments while the PEQ dialog is open, was erratic. Anyone finding a real world application for linking many filters together wins a free RaneGauge – just email hal@rane.com.
  13. Web Controls User Access dialog was not resetting to Off when a new Halogen configuration is opened.
  14. Web Controls User Access did not work when the HAL date/time clock was not set correctly.

Known issues in Halogen 4.1

  1. When pasting or moving blocks or wires so the wire ends align properly with block I/O nodes, sometimes the wires do not connect to the nodes. Workaround is to select the dashed-red wire end and move it off, then back on to the node.
  2. The Pager1 Talk button cannot be overridden in Halogen like the other read-only (Logic) I/O controls.
  3. Zone Page Active status does not turn off when a zone is removed from a scenario when the active status is linked to a toggle control.
  4. Sometimes, the on-screen GEQ sliders get stuck and stop moving, although the displayed graph and audio both update properly. We’ve been unable to reproduce this.
  5. When two Web Control Pages contain the same Toggle control that both link to a read-only control (e.g., a HAL Logic Input), clicking the toggle on one page briefly toggles the other web page’s control even though neither web control is able to change the state – even temporarily.
  6. After putting a Connected HAL’s computer to sleep, the Connected HAL remains in the In Use state for 10 to 15 minutes. Other computers on the network cannot connect. Workarounds are: Disconnect Halogen or unplug the Ethernet cable to the HAL before sleeping the computer or reboot the HAL.

Halogen 4.1.1 Single File Halogen Installer (400M)

This file does not require an internet connection to install Halogen.

New Features in Halogen 4.1

HAL & Halogen software

  1. Completely updated the Hardware Workspace that eases configuring, viewing, editing, finding, swapping, moving, and troubleshooting EXPs, DRs and RADs, – especially in larger systems. Swap, move or insert anything from anywhere to anywhere with ease.
  2. Improved the overall speed and performance of dozens of operations that were notoriously slow, and updated the progress meter which was often stuck or disappeared before operations were complete. Operations such as opening large Halogen files, moving the Birdseye zoom around in large files, opening the HW Controls tab containing many devices, adding / removing nodes or the 11th wall in large room combine blocks are faster.
  3. Added support for the HAL3s.

Processing Workspace

  1. Changed from using names to numbers in the Workspace Label and Wire Tag color selection dialog.
  2. Improved the All Presets dialog by allowing it to resize to a smaller minimum size and by allowing custom resizing of the Active Presets panel.
  3. Changed the default Threshold on Compressors to -20 dB (from -40)
  4. Made all three Processing Workspace Tabs accessible at Halogen’s minimum screen resolution. The tabs names were shortened to I/O, DSP & HW.
  5. Adjusted the zoom level on the Fit button for better zooming in large systems.

Hardware Workspace

  1. Adjusted the zoom level on the Fit button for better zooming in large systems.

Bug fixes in Halogen 4.1

  1. The Distance and Temperature fields in the Distance Delay block were not updating when typing in numeric values, although the delay distance and temperature were being set to the typed values correctly. The displayed values were not updating.
  2. The Mic gain control in the RAD16 input block was being initialized improperly. It wrongly permitted adjusting Line gain.
  3. The processing map position was not reset to center when creating a new configuration or opening an existing configuration. This would cause problems in viewing an existing configuration on opening or positioning new blocks and wires.
  4. Bugs relating to the maximum size of Web Controls Image files were fixed. One permitted sizing images beyond the max workspace size (5,000 by 5,000), another allowed exceeding the maximum total image size permitted (15 MB).
  5. Meters froze after simultaneously opening several processing workspace dialogs in Halogen. This operation caused a failure of the HAL meter server which was recoverable by rebooting the HAL.
  6. Meters on a Mixer Input block froze after deleting an input node. The meter was pointing to the deleted, not the remaining input.
  7. Linking multiple of the Paging Manager’s Page Active Links to a single output logic (relay) with Presets to allow priority override (e.g., Fire Marshall) caused Inactivating Links to enter the Twilight Zone (not working correctly).
  8. Room Combine wall states were not displayed correctly in Halogen (although the walls work) when linking read-only (logic input switches) to walls.
  9. Adding a branch wire to an existing wire, then deleting it sometimes crashed Halogen.
  10. Very occasionally when the HAL’s Notes file is empty, it was impossible to connect Halogen to a live HAL.
  11. The Delay Max value was not properly saved when changed immediately after being disconnected from a live HAL.
  12. Copying multiple Wire Tags to the clipboard, then pasting them sometimes caused a crash. This had something to do with the order the objects in the clipboard were selected.
  13. RAD Labels were not being generated for RADs in EXPs that are after an EXP7 AEC Expander in the Expansion Bus.
  14. The “150 Room Processors Max” indicator was not being displayed below the Conference Room Combine block when exceeding the maximum number of Room Processors.

Known issues in Halogen 4.1

  1. When pasting or moving blocks or wires so the wire ends align properly with block I/O nodes, sometimes the wires do not connect to the nodes. Workaround is to select the dashed-red wire end and move it off, then back on to the node.
  2. The PAGER1 Talk button cannot be overridden in Halogen like the other read-only (Logic) I/O controls.
  3. Zone Page Active status does not turn off when a zone is removed from a scenario when the active status is linked to a toggle control.
  4. Sometimes, the on-screen GEQ sliders get stuck and stop moving, although the displayed graph and audio both update properly. We’ve been unable to reproduce this.
  5. When two Web Control Pages contain the same Toggle control that both link to a read-only control (e.g., a HAL Logic Input), clicking the toggle on one page briefly toggles the other web page’s control even though neither web control is able to change the state – even temporarily.
  6. After putting a Connected HAL’s computer to sleep, the Connected HAL remains in the In Use state for 10 to 15 minutes. Other computers on the network cannot connect. Workarounds are: Disconnect Halogen or unplug the Ethernet cable to the HAL before sleeping the computer or reboot the HAL.

Halogen 4.1.0 Single File Halogen Installer (400M)

This file does not require an internet connection to install Halogen.

Fixes in Halogen 4.0.1

  1. When the HAL4 input is set to dynamic mic or condenser mic, typing a numeric gain value in resulted in an incorrect gain setting. The rainbow control and up/down arrows worked correctly.
  2. The HAL4 DSP Resource was not 0% for empty configuration files.
  3. Adding an EXP3x Zone Processor Priority Selector in a preset resulted in a configuration file that Halogen could not open.
  4. Links to Logic Input pins configured as selectors on a pasted DR4 (in the Hardware Workspace) responded to changes on the original/source DR4 port.
  5. Audio morphing in the Pager1 and Paging Station PEQ blocks was not working as it was in all the other PEQ blocks. This was causing low-level zipper noise when quickly moving PEQ filters around in the Pager1 and Paging Station blocks on live devices.
  6. When a Web Controls Command Label was toggled to display no text (“Show” was unchecked), the text vanished from Halogen, but still appeared in the URL when web page is displayed.
  7. Using image files that are “read-only” was causing headaches when used in Web Controls.
  8. Within DSP blocks containing graphs (e.g., PEQ, ANC, others), when grabbing movable nodes with the mouse, moving the node outside the bounds of the graph caused the mouse to stop controlling the node.
  9. When adding and subtracting delay blocks in configuration files that exceed 100% DSP Resource, the delay resource value was showing wrong values.
  10. Starter Configuration files failed to open when the last file saved was to a Flash drive that was no longer plugged in.
  11. Long Meter Group Names were partially hidden.
  12. The Help file contained typos.

Halogen 4.0.1 Single File Halogen Installer (390M)

This file does not require an internet connection to install Halogen.

New features in Halogen 4.0

  1. Added support for two new hardware products: HAL4 (2-channel) and EXP7x (AEC Expander for the HAL1x).
  2. Added Web Controls: completely customizable web pages from within Halogen – control any HAL from an iPad, smart phone, tablet PC, etc. Firmware update is required in any existing HAL.
  3. Added a second gain setting to the Pager1 mic input stage to better support “hot” mics.
  4. Added Network Troubleshooter diagnostics interface.
  5. Add a “thBroadcastReceiver” link in the Halogen Start Menu group to help troubleshoot communications between HAL and Halogen.

Processing Workspace

  1. Added max/min settings to all Mixer, Matrix Mixer, and Room Combine Mixer cross point Level controls.
  2. Added max/min settings and Links to all PEQ gain, frequency and bandwidth controls. This is useful for creating links for remote Tone Controls from DR remotes or iPads (etc.) using the new Web Controls feature.
  3. Added a new Voice Detect DSP block that does lots of cool stuff for live or recorded paging applications, especially when links to physical switches or Ethernet control systems are needed.

Hardware Workspace

  1. Halogen now displays a read-only warning message, when trying to load a configuration file from a read-only folder.

Bug fixes in Halogen 4.0

  1. RaneLink crashed when a router was configured to always return "in use" messages for all ARP requests. This prevented valid link local IP Addresses in HALs which are required to talk to Halogen.
  2. Fixed graphics problems where parts of windows were not fully visible due to Windows magnification settings.
  3. I/O meters were erroneously enabled when RADs were in a mismatched state.
  4. EXP3x output meters sometimes showed full-tilt boogie after a Hardware Workspace swap – although audio was working fine.
  5. Rooms became Inactive if added by holding down Shift while dragging the block onto the Workspace and then selecting more than three rooms.
  6. The first audio channel onto the Expansion Bus always had an LSB bit equal to zero. But since it’s 24-bit audio, this was always deep into the noise floor and inaudible.
  7. Deleting the active preset within a selector preset did not activate the newly selected preset.

Halogen 4.0.0 Single File Halogen Installer (390M)

This file does not require an internet connection to install Halogen.

Fixes in Halogen 3.0.1

  1. Fixed the expansion bus link that occasionally dropped when more than 16 expansion units are attached.
  2. Disconnecting a DR while it is in Locate mode caused Halogen to crash.
  3. Sometimes when a device mismatch state exists, meters were not graphically disabled.
  4. Meters were not working for RADs when attached to an EXP1x or EXP3x.
  5. Toggle controls were not displayed on a DR2 or DR3 when switching control mode from Selector to Toggle/Command mode.
  6. Halogen didn't turn off the device locate LED before swapping a device in the hardware workspace.

Known issues in Halogen 3.0.1

  1. In Halogen 3.0 or greater, deleting or adding an input node on a Gain-sharing Auto Mixer in a file created before Halogen 3.0 crashes Halogen. (You chose "backup and update," didn't you?)  The simple fix is to delete the entire Gain-sharing Auto Mixer, insert a new one and add the nodes required. This effects only the Gain-sharing Auto Mixer and not the Gain Sharing Matrix Mixer, not the Room Combine block.

  2. When working on configuration files that greatly exceed the 100% Resource value, the delay resources meter can become inaccurate. This does not happen when below 100%.
  3. The Locate indicator in Halogen continues to flash after unplugging the associated hardware device.
  4. Deleting a selector preset sometimes results in none of this preset’s settings being active. Fix by activating any preset in this selector preset.
  5. Pager1 Talk toggle control is not overridable, but should be.
  6. The "Hide All Windows" function clears meter peak holds.

Halogen 3.0.1 Single File Halogen Installer (183M)

This file does not require an internet connection to install Halogen.

New features in Halogen 3.0

HAL & Halogen software

  1. Added support for five new hardware products: HAL1x, EXP1x, EXP3x, EXP5x, RAD27

Processing Workspace

  1. Added support for orthogonal (right angle) wiring and wire branches.
  2. Added Wire Tags – namable I/O wiring “portals” that eliminate wire clutter.
  3. Added Highlight Wires to visually indicate all wires connected to a selected block(s).
  4. Added Links to the Active indicators in Zones to allow control systems or logic outputs to know what paging zone(s) are active.
  5. Added “View HAL Information” to context menu in Windows file system which indicates the HAL device type (HAL1, HAL2 or HAL3) and the Halogen version number for a Halogen configuration file.
  6. DR1 & DR3 remote LCD Levels now indicate the ratiometric percentage for the current volume setting. 0% for off, 100% for full-tilt boogie.
  7. All toggle checkboxes now use a check mark, rather than an ’x’ to indicate status.
  8. Processing Blocks that contain child blocks now graphically appear with a double outline.
  9. Halogen desktop icon now shows the Halogen version number in the name.

Hardware Workspace

  1. The EXP device’s physical position along the Expansion Bus is now shown.

Bug fixes in Halogen 3.0

  1. Halogen now correctly displays the subnet mask value that is in the HAL. All subnet values were correctly sent to HAL, and hardware and network functionality was not impaired, although the displayed subnet values always appeared as either 0 or 255 in Halogen. Other values could not be altered after initially setting them. (4967)
  2. The Paging Station Scenario list & Room Combinations Selector did not scroll when linked to a read only control (4536 & 4545)
  3. HAL3 front panel Sig/OL LEDs on the Line-Plus Inputs did not illuminate unless a Line-Plus Input block was added to the Processing Map (4140)
  4. The units value (feet or meters) in delay blocks was not pasting into pre-existing delay blocks. (4430)
  5. Bypass all for the feedback suppressor was not shown as a graphical wire on the response graph (it displayed the pre-bypass response).
  6. Halogen did not cancel feedback suppressor auto setup mode upon disconnect from HAL (4539)
  7. On RAD inputs, the physical Sig/OL indicators were sensed pre-input sensitivity, not post. (4574)
  8. HAL2 and HAL3 always sent zero as their serial number to Halogen (4636)
  9. A meter initialization error upon first opening a Halogen properties dialog was confusing. It implied audio was present, but it was not. (4679)
  10. European decimal separator ,  was causing grief with Max and Min values (4591 & 4592)
  11. Adding 32 audio channels to the Distributed Program Bus in a configuration file containing 12 room combine rooms with 11 walls (81 rooms total) took over 4 minutes – now it takes only a few seconds. (4513)

Known issues in Halogen 3.0

  1. In Halogen 3.0 or greater, deleting or adding an input node on a Gain-sharing Auto Mixer in a file created before Halogen 3.0 crashes Halogen. (You chose "backup and update," didn't you?)  The simple fix is to delete the entire Gain-sharing Auto Mixer, insert a new one and add the nodes required. This effects only the Gain-sharing Auto Mixer and not the Gain Sharing Matrix Mixer, not the Room Combine block.
  2. Disconnecting a DR while it is in Locate mode causes Halogen to crash.
  3. Sometimes when a device mismatch state exists, meters are not graphically disabled.
  4. When working on configuration files that greatly exceed the 100% Resource value, the delay resources meter can become inaccurate. This does not happen when below 100%.
  5. The Locate indicator in Halogen continues to flash after unplugging the associated hardware device.
  6. Deleting a selector preset sometimes results in none of this preset’s settings being active. Fix by activating any preset in this selector preset.

Halogen 3.0.0 Single File Halogen Installer (201M)

This file does not require an internet connection to install Halogen.

New features in Halogen 2.0

HAL & Halogen software

  1. Added support for six new hardware products: HAL2, HAL3, DR4, DR5, RAD17 & RAD24
  2. Added support for two new DSP blocks:
    • Ambient Noise Sensing to adjust page or program music volume as the noise in rooms changes.
    • Feedback Suppressor that constantly listens for acoustic feedback and deploys notch filters to illuminate squeals.

Processing Workspace

  1. Added support in a single Room Combine Processor for 12 rooms containing 11 walls maximum.
  2. Exposed each Room Processor’s Level and Selector Links in the Room Processors Tab to avoid having to open so many dialogs when dragging room links together.
  3. If you need any of the following characters, Halogen 2.0 now has them: á, é, í, ó, ú, ý, ø, ö, ø, å, æ, ä, ö, à, è, ñ, and many more. Any Latin character is available in all editable names in the Halogen software and in the LCD screens for DR1, DR2 and DR3.
  4. Added multi-node wiring. Auto-create multiple wires between blocks by first selecting the starting nodes, clicking on any of them to start wiring, and then hovering over the ending block(s) or node(s). Wires are auto-created between the selected starting nodes and available nodes on the ending block(s).
  5. Align and/or evenly distribute a group of blocks by selecting the blocks and then applying the desired alignment function from the Processing Workspace Toolbar or Right-click: Align left, right, top, bottom, plus horizontal and vertical spacing distribution.
  6. Added Text Labels to label sections of the Processing Workspace.
  7. Added port indicators to upper left title bar in I/O blocks on Processing Map. These indicators show the hardware path as well as hardware match/mismatch information for RAD I/O blocks.
  8. Double-click any I/O or Host Processing icon in the palette to place it on the Processing Workspace.
  9. Read-only controls (physical switches, pots, relays…) can now be overridden in software for behavior verification, then canceling Override returns settings to physical controls’ current state.
  10. Paging Manager now has a single Check All box to assign all Zones to a Scenario or all Scenarios to a paging Station.
  11. Added Ctrl+Tab shortcut key combination to move focus to the next open property window. Shift+Ctrl+Tab moves backward through open property windows.
  12. Added enhanced multi-select of processing blocks using any combination of control clicking and dragging a selection window.
  13. Added a Preference to allow wires to appear curved or rounded in the Processing Workspace.
  14. Added ability to paste the Feedback Suppressor’s filters into a PEQ block as long as both blocks contain the same number of filters. This may be useful in systems where the mics and loudspeakers never move and the temperature is stable.
  15. Added a Preset drag target to the Link Properties dialog to permit storing Links to Presets without doing so from the All Links dialog.
  16. Added the ability to duplicate existing Presets. Thus speeding the workflow when creating many, slightly different presets contain many of the same settings.

Hardware Workspace

  1. Enhanced the Device Mismatch indicators to be more descriptive: Device Mismatch (device configured is not the device HAL detected); Device Missing (device configured but none detected); Device Unexpected (no device configured, but a device is detected).

Bug fixes in Halogen 2.0

  1. The audio taper behavior of full-range Level blocks was in the Twilight Zone (erroneous). It’s back to reality. (4040)
  2. Spin controls (up/down buttons) still accelerate quickly yet now they actually stop when desired (4123)
  3. Now pasted wires with endpoints that land on an Add node, are wired. (1985)
  4. Keyboard shortcut for accessing the Control Systems dialog (Ctrl + B) was missing from the Help file. Fortunately, no one was injured. (4078)
  5. Adding a PEQ or All-pass Filter while Bypass All is checked resulted in a misleading graph. (4076)
  6. The Zone Processor Priority Selector settings were lost or improperly reset when closing and reopening Halogen or repowering HAL. (4073)
  7. Halogen became unhappy when Video or Distance Delay Max values are rapidly changed irrationally. (4039)
  8. Windows XP and Windows 7 no longer require two reboots while installing Halogen. We found a work around to this Microsoft-created issue. (3995)

Known issues in Halogen 2.0

  1. The Feedback Suppressor’s response graph does not show a flat “wire” response when Bypass All is checked – although the block is bypassed. (4528)
  2. Installing Halogen from the DVD in the HAL box, then re-installing Halogen form Rane’s website, causes an error. Work around is to manually uninstall Halogen. (4565)
  3. Using many Distributed Program Bus (DPB) channels along with many room combine processors – such as 12 rooms, 10 walls – can take several minutes for Halogen to automatically generate the over 325,000 possible I/O and routing permutations. Be patient. We’re working on improving this in a future release. (4513)
  4. The Pager1 read-only Talk button in a connected HAL is not override-able in Halogen, but it should be. (4442)
  5. Changing a Distance Delay block's Distance value, then changing the Units value, causes copied then pasted Distance Delay blocks to have the wrong the settings. (4430)

Halogen 2.0.0 Single File Halogen Installer (225M)

This file does not require an internet connection to install Halogen.

New features in Halogen 1.2.0

HAL & Halogen software

  1. Added audio morphing which avoids formerly possible clicks or pops when drastic filter changes occur between preset changes (3716). Added to all filter blocks.
  2. Added Ctrl-W as a shortcut key for closing the focused property dialog in both Hardware & Processing Workspaces (3999) Thanks, Alex McLain

Processing Workspace

  1. Enhanced block selection: now permits control-clicking and windowing in any combination (4006)

Bug fixes in Halogen 1.2.0

  1. Deleting a Pager1 from the Hardware Workspace immediately after dragging it onto Processing Workspace was causing an error (4019)
  2. Double-clicking on a Room Combine block’s Sum block hung Halogen (4022)
  3. Parent blocks now turn red when child block(s) are muted. Added to Pager Input and Paging Station (3175)
  4. When DHCP is enabled on a PC on a network with no DHCP server, HAL would inconveniently disconnect shortly after a new link-local address is added by Halogen. Now, preexisting link-local addresses in the PC are used by Halogen rather than Halogen always adding a new one (3994)
  5. Uninstall now removes firewall rules avoiding duplicate firewall entries upon reinstalling Halogen (3996)
  6. Level controls did not display correctly after activating a preset that changed the min/max values (3970)
  7. Sometimes wires appear dotted rather than solid after moving old blocks only horizontally and wiring to just dropped new blocks (4041)
  8. Some blocks’ ‘rainbow’ slider controls were jerky while being adjusted (4037 & 4038)
  9. After a save, close and file reopen, Delay and Level blocks erroneously permitted deleting only input nodes, when both input and output nodes should always be deleted together on these blocks. (4010)
  10. After adding a new DR, then viewing the Processing workspace, then returning to the Hardware workspace and changing the DR to a RAD, the RAD was not being shown in the Processing workspace (4036)
  11. Corrected some filename typos in the help and readme files that pointed to the 3rd-party help documents (3971 & 3972)
  12. Duck block ‘ducked’ indicator was turning off at the wrong time. Now it turns off after the hold time, but before ramping begins. (3679)
  13. Multiple DR windows were opening from the Link dialog after moving or swapping EXPs that contain linked DRs. (3963)
  14. The meter server between HAL & Halogen is much more robust now. Added more automatic retries and user warnings are displayed if speed bumps are encountered (3960 & 4015)
  15. Some email clients were hanging Halogen when “Send email to Rane” was clicked (4018)
  16. Extended the time before deleting troubleshooting log files from 2 days to 2 weeks (4021)
  17. Sometimes rapidly changing the max delay (like a two year old would) in Distance or Video delay block caused Halogen unhappiness (4039)
  18. Two bugs that created corrupted files when Halogen upgraded much older Halogen files were fixed (3961 & 4010)

Known issues in Halogen 1.2.0

  1. If a Windows XP or Windows 7 computer does not have Microsoft .NET 4.0 installed, the Halogen installer does install/update it. But during installation, two reboots are required: one after the .NET Client installs and a second reboot after the .NET Framework installs. We know, what a pain in the tush. And you thought Microsoft cared about your time, or at least moved on from requiring reboots during installs. Take the added time to think happy thoughts – such as your favorite dessert or gelato flavor.
  2. The Zone Processor Priority Selector settings are lost or improperly reset when closing and reopening Halogen or repowering HAL. The fix is to drag and configure the Distributed Program Bus (DPB) first, then drag on the Zone Processors.
  3. To fix this:

1. Delete the DPB and the Zone Processor blocks.
2. Add the DPB and configure the inputs.
3. Add the Zone Processor(s) and configure the selectors.
4. Save the config and open it – all will be well.

Halogen 1.2.0 Single File Halogen Installer (233M)

This file does not require an internet connection to install Halogen.

New features in Halogen 1.1.0

HAL & Halogen software

  1. Added support for external Ethernet control systems.
    • Support packages for AMX, Crestron, and Stardraw Control.
    • Control Systems button & dialog in processing workspace added to configure controls.
    • Halogen/HAL1 Control Server – supports multiple clients.
    • Allows complete development and 100% testing of control systems with only Halogen software – no hardware required for developers.
    • All HAL/Halogen linkable Level controls are automatically and quietly ramped in the DSP, thus programmers can send fast and/or drastic level value changes without worrying about audio pops and burps.
  2. Enter a subnet mask for HAL1’s static IP Address in the live HAL1 properties dialog.
  3. Enter a default gateway for a HAL1 in the live HAL1 properties dialog.
  4. Disallow disabling of DHCP on a HAL when connected to that HAL's DHCP-assigned address. If the DHCP address is being used for the connection between Halogen and HAL, the user is prevented from turning off DHCP and a message box appears to tell them this and why.
  5. Open property dialogs near blocks, devices, or hyperlinks. When opening property dialogs, Halogen now opens dialogs just below the clicked block, device, or hyperlink (not below the previously opened dialog as in the previous version of Halogen).
  6. Added ‘Close’, ‘Close All’, and ‘Close All But This’ to all dialog context menus – right-click in any title bar.

Hardware Workspace

  1. Temporarily hide open dialogs when dragging from the palette.
  2. Temporarily hide open dialogs when panning or zooming the birdseye view.
  3. Temporarily hide open dialogs when moving or swapping a device in the hardware map.
  4. Right-click context menu in the palette now includes ‘Show All’ and ‘Hide All.’
  5. Added a Help menu item to zip all Halogen log files and allow saving the zip to a directory.
    • Captures all Halogen and ‘pcops’ log files – this is intended to be done with direction from Rane so users can send zip files to Rane for troubleshooting and analysis.
    • Located in the Help menu (Save log files).

Processing Workspace

  1. Support for external Ethernet control systems.
    • Support packages for AMX, Crestron, and Stardraw Control.
    • Control Systems button & dialog added to configure 3rd-party controls.
  2. Bulk drag of I/O blocks.
    • Shift-click selects sets of I/O palette blocks for multi-dropping in the Processing map with a single drag/drop.
    • Click headings to select whole groups of I/O, or shift-click headings to select custom sets via multi-select.
  3. Drag and drop multiple copies of Host Processing blocks to the Processing map. Hold down any number 1 through 0 while dropping a block, 1 through 10 blocks are added. Number key must be held down while releasing mouse.
  4. Specify number of I/O when dropping a variable I/O Host Processing block. Hold shift down while dropping a variable I/O block - a popup asks how many I/O nodes to add.
  5. Selector, Priority Selector and Router blocks (including those in Zone Processor and Room Processor blocks) show the currently selected node in maroon colored text on the block. On the Priority Selector, the currently selected maroon text on the block does automatically move as higher priority input audio is auto-detected. But the radios buttons in both the property dialog and any linked DR remote(s) continue to show the most recent physically selected input – not the auto-detected priority input.
  6. On I/O blocks, show the physical port number on the Processing map. Hover the mouse over an I/O block in the Processing map, the physical HAL or EXP1 port number appears in the title bar on the upper left corner. Open the dialog to view the full physical path to the device (e.g., which EXP1 in a chain).
  7. Meter button & Meter Window added. Drag and drop any meter to the Meter Window – 8 meters per meter page, 40 meter pages.
  8. When an AM2 mixer(s) is cascaded in the Room Combine block, the physical port number for that AM2’s HAL or EXP1 port is displayed.
  9. Show the number of filters in the PEQ and All-pass filter blocks. The number of filters displays in the block title bar as ‘x n’ where n is the number of filters – e.g., x 6 for 6 filters. The PEQ’s high- and low-cut filters are not included in this value.
  10. The I/O and HW Control palettes show the physical HAL or EXP1 port numbers. The palette title bar for the HAL1 and each EXP1 contains a port position number. This makes it easier to figure out which physical HAL or EXP1 port a device is connected to.
  11. Temporarily hide open dialogs when dragging from I/O and Host Processing palette.
  12. Temporarily hide open dialogs when panning or zooming the birdseye view.
  13. Temporarily hide open dialogs when shift-click panning.
  14. Temporarily hide open dialogs when moving any block or wire.
  15. Auto scroll the Processing map when moving an existing block or wire.
  16. Blocks containing child blocks now contain a right-click context menu that allows opening child block property dialogs without having to open the parent block. A fly out appears showing all child blocks, allowing you to pick one. Applies to Pager1, Paging Station, Zone Processor, and the individual Room Processors in the Room Processors tab (not the parent Room Processor since this would require dozens of fly-out menus).
  17. Added bypass and mute to the right-click context menu (for blocks with bypass/mute). When multiple blocks are selected, all blocks must support the bypass/mute function and be in the same state for the context menu to appear.
    • Blocks with mute:
      I/O blocks: all, except Pager1 (including its child blocks), Mic Input and Level
      Filters: all 6 crossover blocks
      Misc: Level, Ramped Noise, Swept Noise, and Sine Wave
      Mixers: all blocks
      Paging/Room Combine blocks: Level child blocks inside Paging Station, Zone Processor, and Room Processors; Mixer child blocks inside Room Processors
    • Blocks with bypass:
      I/O: PAGER1 child blocks: PEQ and Compressor
      Dynamics: all blocks
      Filters: all blocks except the six crossover blocks
      Paging/Room Combine: PEQ and Compressor child blocks inside Paging Station
  18. Property dialogs for blocks, presets and linking now display the block’s category colors. A color bar is preset in the property dialog title bar for all processing block, preset, and linking property dialogs. The bar is in the upper left corner, just to the right of the ‘pin’ icon.

New DR Remote functionality

  1. Allow apostrophes in DR & Pager1 LCD display text – e.g., Men’s Lounge.
  2. Show in software whether or not text fits (left to right) on a DR or Pager1 LCD display. Halogen shows a yellow warning (!) icon next to the LCD edit box when display text won’t fit in the actual LCD display on the given product.
  3. Make it more obvious when a DR executes a Command. The icon for the Command item shown in the DR LCD display flashes more prominently when the user clicks the item (by pressing the DR button).
  4. Slowed down the ‘spin’ rate when using the arrow buttons to adjust DR and Pager1 LCD backlight.

Bug fixes in Halogen 1.1.0

  1. Fixed Non-US English versions of Microsoft Windows installations that were exhibiting problems after dragging a ducker, limiter or gate onto the Processing map. (3751)
  2. After moving or swapping DR remotes on the Hardware workspace, the DR label name(s) and Enable state(s) were being reset to their defaults. This forced names to be reentered after moving or swapping. (3736)
  3. DR remotes were improperly restricted to displaying 16 maximum entries, not the intended 20 max that are now supported by all DR and Pager1 devices. (3838)
  4. The Ctrl-D shortcut key to open the All Presets dialog was not working. (3830)
  5. Deleted nodes of copied Level and Selector blocks were being pasted to new blocks. (3861)
  6. Wiring or moving blocks near the edges of the Processing map did not auto scroll. (2798)
  7. Text edit icon disappeared in DR hardware properties dialog after entering very long names. (3907)
  8.  Configuration Notes were not displayed the first time you re-open a configuration file containing notes. The second time you open the file they returned as expected. (3943)
  9. Swapping EXPs was causing their RAD/DR devices to stop working. (3823)
  10. Linking a toggle preset and a toggle control, then changing the link value in the Link window was causing problems. (3854)
  11. The last character in DR or Pager1 LCD display names was sometimes hidden by the scrollbar. (3898)
  12. After deleting a preset that contained a Level block, nodes would no longer Add correctly to that Level block. (3968)
  13. Links to Selector Presets stopped working after reopening configuration file. (3967)  Link names were also initially missing in this situation (3966)
  14. The Help file states the maximum number of HAL IP Addresses was 10. But the actual limit is 8 IP Addresses. (3957)
  15. Unplugging the Ethernet cable before a Connection transfer is complete caused Halogen processes to continue running – even after closing Halogen. (3954
  16. HAL was not changing its IP Address after the DHCP server changes its IP range and the HAL DHCP lease expired. (3951)
  17. HAL was accepting DHCP IP Addresses that were already present on the network. Now HAL verifies that the IP Address sent by the DHCP server is not in use. (3946)
  18. HAL was not sending its hostname to the DHCP server (3947)
  19. Leaving a live device’s meters open in Halogen for over 2 weeks, 24/7 eventually caused the meters to stop, requiring a re-launch of the Halogen software to have meters again. (3742)

Known issues in Halogen 1.1.0

  1. If a Windows XP or Windows 7 computer does not have Microsoft .NET 4.0 installed, the Halogen installer does install/update it. But during installation, two reboots are required: one after the .NET Client installs and a second reboot after the .NET Framework installs. We know, what a pain in the butt. And you thought Microsoft cared about your time, or at least moved on from requiring reboots during installs. Take the added time to think happy thoughts – such as your favorite or an upcoming vacation.
  2. Using presets to recall drastic filter changes can cause minor pops in the presence of audio. We’ll be adding filter morphing to the PEQ, Graphic, Cut and Shelf blocks in the next Halogen release to address this.
  3. After dragging a Pager1 to the Processing map, either right-cliking to delete it, or changing the Pager1 to any other RAD, DR or none in the Hardware workspace crashes, then forces Halogen to close. The work around is to first remove/delete the Pager1 from the Processing Map, then delete it or change it in the Hardware workspace.
  4. The Room Processor's Sum block crashes Halogen if you double-click on it. Workaround: Do not double-click the Sum block inside a Room Processor. This block contains no adjustable parameters - so once it's fixed in the upcoming Halogen 1.2, it will not open anyway. Halogen 1.2 is due in late April, 2012 to address all but the Microsoft reboot issue.

Halogen 1.1.0 Single File Halogen Installer (232M)

This file does not require an internet connection to install Halogen.

Version 1.0.1

Version 1.0.1 contains several minor bug fixes.

Known Issues in Halogen 1.0.1

1. "Non-US English" versions of Windows exhibit problems when dragging blocks onto the Processing Map. We recommend changing the Windows setting that changes the symbol used for "decimal points" from a comma ( , ) to a period ( . ).  This temporary workaround fixes the problems until an updated release is available.

The problems encountered are: adding a ducker, gate or limiter block displays an error that corrupts the configuration file. The delay block resources used value is calculated incorrectly. And Level control links and parametric EQ bandwidth values behave incorrectly.

Here's where to find the settings in the German version of Windows. Make these changes, then open Halogen:

  • German Win 7 Pro N
    From the Systemsteuerung, open Region und Sprache
    Click on Weitere Einstellungen…  the button in the lower right corner of the screen (on the Formate tab)
    Replace the ‘,’ in the Dezimaltrennzeichen field with a ‘.’
  • Windows XP N 
    Systemsteuerung -> Regions und Sprachoptionen
    Click on the Anpassen… button next to the region
    Change the dezimaltrennzeichen value to ‘.’ Instead of ‘,’
  • Windows Vista:
    Systemsteuerung -> Regions- und Sprachoptionen
    Click on the Dieses Format anpassen… button in the lower right of the dialog
    Dezimaltrennzeichen field

2. Halogen will not run with .NET framework 4.0 on Vista SP2. Vista SP1 works fine as do the other versions of Windows we currently support

Control HAL

Halogen Web Controls

Control the Levels, Selectors, Toggles and Commands in any HAL System from any device with a web browser. Halogen 4.0’s Web Controls feature allows creation of custom HTML GUI control screens. Define the quantity of control pages, and the layout, labeling and size of each control, and completely test them using your default web browser from within Halogen.

Access any control page from any browser-enabled device on the network with a HAL device. Just open a browser and type in the customizable IP/webpage address for the HTML page – and bookmark it for easy access. Type in the (optional) 6 digit User Access code, and voilà, the trick, she is done! Control your HAL system wirelessly from one or more tablets, smart phones, laptops or desktop computers. The HAL web server is multi-client, allowing control across many devices and many rooms. You can link Rane’s wired DR remote controls (DR1, DR2 & DR3) and wireless devices and they’ll automatically track each other.

Customers from almost every audio application are asking for “iPad control” and Halogen’s Web Controls is the solution. It is not Apple®-centric — no iTunes® store or app installs required. We’ll save a lot of space on this page by not listing all the possible devices that support web browsers and wireless Ethernet. Besides, the list will update before we know it.

Web control across devices

Halogen Web Controls

DR1 Level Remote

The Rane DR1 is a Level Control remote with several features that make it stand out against any other wired remote. The LCD display shows the name of the Zone or Group that it is connected to, customizable in Halogen Software to anything you like. The Level value is also shown, and updated dynamically when it is changed elsewhere, such as in a linked group with multiple Remotes connected. The display has a backlight for readability that turns on when used, then dims after a short time period.

The DR1 fits in a standard U.S. electrical box and comes with a matching Decora plate cover.

Home run shielded CAT 5e connections to the HAL or EXP (up to 300 meters [1,000 feet] away) eliminate addressing, external power, and the need to test the cables.

DR1 Side

To mount Rane DR1s in a rack, we recommend Lowell rack panels. Note: Lowell's 8-wide panel accepts only single gang devices and does not accept two-gang devices such as Rane RADs or DR2 or DR3. Use Lowell's 9-wide model which accepts multi-gang Decora products.

DR2 Selection Remote

DR3 Digital Remotes

Single Selector

 

DR3 Digital Remotes

List of Toggles / Commands

 

The DR2 offers both Single Selector and List of Toggles/Commands behaviors. The LCD display has a backlight for readability that turns on when used, then dims after a short time period. The selection names are customizable in Halogen Software to anything you like.

The DR2 fits in a standard double-wide U.S. electrical box and comes with a matching Decora plate cover.

Home run shielded CAT 5e connections to the HAL or EXP (up to 300 meters [1000 feet] away) eliminate addressing, external power, and the need to test the cables.

DR4 Logic I/O Expander

DR4 Logic I/O Remote

  • 8 Logic Inputs, Internal 5V pull-up
  • 8 Logic Outputs for relay drive, LED or logic level output
  • 8 Analog Control ADC inputs for potentiometers
  • 6 IR ports for IR2 wall sensors

DR4 rear

The DR4 Digital Remote adds additional logic input and output ports to any HAL, enabling simple analog level and logic I/O controls plus IR2 remotes for wall sensing, enabling automatic sound routing when moveable walls open and close. The DR4 offers eight logic ins and outs, six IR2 ports and eight analog control input ports for pot-on-a-wall level control. Multiple DR4's can connect to Digital Remote Ports on any HAL, up to 300 meters (1000 feet) away.

Logic Inputs

DR4 Open SwitchThese inputs on the DR4 are similar to the Logic In ports on a HAL. You can configure each of the eight input ports in one of three ways: toggle, command, or selector.

The Toggle configuration allows a Toggle command with an on/off switch. You can configure each port type to be either Momentary or Latching.

DR4 Multiposition SwitchThe Command configuration allows triggering a Command control from an on/off switch, which can link to one or more Command controls such as a Command preset or a linkable button in a processing block property dialog.

 

DR4 Binary SwitchThe Selector configuration uses either a multi-position switch or a binary switch. You can connect a physical device to any or all of the Logic In ports and configure the ports in Halogen so that they make the desired selection according to the state of the physical device. Wiring details are in the Halogen Software Help.

Logic Outputs

DR4 Logic OutYou can configure each of the 8 output ports in one of 2 ways:

  • Toggle: When a toggle control in the Halogen Control palette is unchecked, HAL sets the corresponding DR4 Logic Out port to logic high (5 V), and when the toggle is checked, it sets the port to logic low (0 V).
  • Selector: When a selector control in the Halogen Control palette is set to the first selection, HAL sets the corresponding DR4 Logic Out port to logic high (5 V). Conversely, when the selector control is in the second position, HAL sets the port to logic low (0 V).

Analog Control Inputs

DR4 Analog InputsEach port allows an analog voltage source to control the value of a Level control in the Halogen Control palette. The input range for the port is from 0 V to 5 V, where 0 V corresponds to 0% on the associated Level control and 5 V corresponds to 100%. Connect a physical linear-taper potentiometer, like the Rane VR2 Volume Remote. The Vc wiper provides the control voltage to the DR4. As you adjust the pot the voltage changes, which in turn changes any linked Level control in Halogen.

IR Remote Inputs

The IR ports are ideal for linking to the wall toggle controls in a Room Combine block, allowing automatic room configuration changes to occur as moveable walls change positions in a physical room. These ports are read-only, intended for the Rane IR2 (see its data sheet). When the IR Remote is sensing infrared the wall is considered ‘open’ and the associated toggle control in the Hardware Controls palette is checked.

DR5 Switch Controller

DR5 Switch Controller Remote

The DR5 Digital Remote offers additional logic input and output ports, enabling the use of simple analog switch controls in any HAL system. Lighted switch panels for room combine applications are easily integrated into a HAL system using the eight switch inputs and eight LEDs outputs on the DR5. Unlike the HAL and DR4 Logic I/O, the DR5 Logic Out is intended to drive the LED indicator on a room combine panel, and is a writable parameter. The DR5 is designed to fit in a standard US dual-gang electrical box, or mount directly near a room combine panel.

DR5 Wiring

New DR6 Touchscreen Remote

The DR6 is a fully customizable touchscreen remote for the HAL family, arriving late 2014. It supports multiple pages or tabs and any set of levels, toggles, selectors and/or commands. Drag, drop and resize controls any way that’s desired. Use custom background images and logos in full-color on the 7-inch LCD display.

Screw the included wall-mount bracket over U.S. or international electrical boxes, or flush mount the 3/4" thick DR6 with a 2-inch (5 cm) square hole in the wall to accommodate the cable. The optional DS1 desk stand accessory (shown) allows the DR6 to rest or mount on a horizontal surface. The optional RB1 rack bracket securely installs a DR6 into a 19" equipment rack.

The included midspan power injector (not PoE) connects shielded CAT 5e (or better) cables between any HAL and the DR6 to deliver communications and the extra power needed for the display.

Optional, on-screen User Access logins secure management pages from public or staff use, and a programmable ambient light sensor automatically dims the backlight.

The Control Page Designer in Halogen 5.0 allows you to create one set of pages and use them in a web control design, DR6 display or both.

IR2 Infrared Wall Sensors

IR2

The Rane IR2R and IR2S are collectively known as an IR2. They work in pairs as an accessory to Rane HAL products. The IR2S sends infrared, the IR2R receives it. They work as a pair to provide an automatic way to sense the position of a movable wall or door. Mounting brackets and screws are included.

A single CAT 5e cable for each door connects the IR2 pair to a dedicated IR Remote port on the rear of a HAL2 or a DR4, which can be up to 300 meters (1000 feet) away. The DR4 connects to any HAL, up to 300 more meters away. Thus, the IR2 can be 600 meters (2,000 feet) away from a HAL.

When mounted on opposite sides of the door, and wired correctly, green indicators on the IR2R and IR2S are always lit. Only when the door is open and the IR2R is receiving infrared from the sender does the IR2R's amber indicator light. Depending on the IR2 mounting height and your eyeglass prescription, these indicators can usually be viewed from the floor. Note that the HAL need not have a configuration loaded in it for the above functionality to be observed. A powered HAL2 or DR4 is sufficient.

For an IR2 remote to control audio, the IR2 requires a connection to a HAL2, or to a DR4 connected to any HAL. In either case, the HAL must be loaded with a suitable configuration. When doors or movable partitions are opened or closed the IR2 automatically detects this, and the audio system reconfigures itself appropriately and automatically.

The IR2 will operate up to 1.5 meters (6 feet). The HAL does not automatically check IR2 wiring errors. See the IR2 Data Sheet for details.

Logic Inputs

Logic In SwitchThese inputs are found on the HAL1x, HAL2 and HAL3s. More can be added with the DR4 or DR5 connectable to any HAL. You can configure each of the Logic Input ports in one of three ways: toggle, command, or selector.

The Toggle configuration allows a Toggle command with an on/off switch. You can configure each port type to be either Momentary or Latching.

Logic In Muti-switchThe Command configuration allows triggering a Command control from an on/off switch, which can link to one or more Command controls such as a Command preset or a linkable button in a processing block property dialog.

 

Logic In Binary SwitchThe Selector configuration uses either a multi-position switch or a binary switch. You can connect a physical device to any or all of the Logic In ports and configure the ports in Halogen so that they make the desired selection according to the state of the physical device. Wiring details are in the Halogen Software Help. The Selector configuration is not supported by the DR5.

Logic Outputs

Logic Out portThese outputs are found on the EXP3x Output Expander for the HAL1x, or on a DR4 that can connect to any HAL. You can configure each of the 8 output ports in one of 2 ways:

  • Toggle: When a toggle control in the Halogen Control palette is unchecked, HAL sets the corresponding DR4 Logic Out port to logic high (5 V), and when the toggle is checked, it sets the port to logic low (0 V).
  • Selector: When a selector control in the Halogen Control palette is set to the first selection, HAL sets the corresponding DR4 Logic Out port to logic high (5 V). Conversely, when the selector control is in the second position, HAL sets the port to logic low (0 V).

Analog Control Inputs

DR4 Analog InputsThese inputs are only found on the DR4 that can connect to any HAL. Each port allows an analog voltage source to control the value of a Level control in the Halogen Control palette. The input range for the port is from 0 V to 5 V, where 0 V corresponds to 0% on the associated Level control and 5 V corresponds to 100%. Connect a physical linear-taper potentiometer, like the Rane VR2 Volume Remote. The Vc wiper provides the control voltage to the DR4. As you adjust the pot the voltage changes, which in turn changes any linked Level control in Halogen.

Relay Outputs

HAL1x Relay OutThese reed relay ports are found on the HAL1x and HAL2 to signal other devices. A common implementation is to link a relay port to a Toggle control so an end user can change its value. Halogen software contains a checkbox for each relay port. Its value can be included in a preset or link to another control, making it possible to use a preset or control to turn the relay port on or off.

Control Linking in Halogen

HAL Control Link

Drag the purple control chain icons atop one another to create links between Levels, Toggles, Selectors and Commands and Digital Remotes, Web Controls and/or 3rd-party controls. These screens show linking a DR1 volume onto the Meeting Room Output Level control.

Four Control Link types and behaviors are supported: Level, Select, Toggle or Command. Activation and Priorities work together for incredible flexibility. Link simple analog remote level controls, contact closures and IR remote wall sensors by adding a DR4 Logic I/O Expander.

Rane HAL Crestron Testimonial

I recently had the pleasure of working on the Hard Rock Casino project as the Crestron programmer, and as you know they had a HAL digital signal processor. Integrating the HAL into my Crestron program was a breeze, it dropped into place seamlessly.
The simple ASCII command protocol makes it easy to understand and implement.
The response from the DSP is also very snappy, so real time feedback is bang on!
Great product, I would highly recommend it to anyone looking to provide an audio solution to both big and small venues.

HAL Applications

Multizone Paging Systems and the PAGER1PAGER1

This RAD is a mic preamp and a paging zone(s) [Scenario] selector with integrated push-to-talk switch. Busy, Caution and Ready indicators inform end users when priorities clash.

The PAGER1 accepts any standard gooseneck mic (not included) and has built-in selectable 24 V Phantom Power and a 13 dB pad. It normally sits on a desk or table, and has lockdown features for security.

The PAGER1 chassis is painted steel, measuring 4.5" x 6" x 2" (11.4 x 15.2 x 5.1 cm). Unit weight is 20 ounces (567 grams).

Distributed Program Bus

Wiring system-wide background music sources into the single Distributed Program Bus automatically wires all music sources to every output zone. The blue Distributed Program Bus label represents bus output and input to blocks.

Halogen Distributed Program Bus

Paging Station and Zones

Paging Station and PAGER1 input DSP blocks automatically connect input page sources (lime green labels) to zones requiring paging.

Halogen Paging DSP Blocks

Thus, wiring from all page sources through the Paging Manager to all page zones – including rooms that combine – is automatic. The Paging Manager easily maps all page sources to any combination of zones when using the Paging Zone, Emergency Page, Zone Processor and Room Combine Processor blocks.

Halogen Paging Manager

Room Combining

Halogen Room Combine Add Inputs and Rooms

The Room Combine Processor supports custom wall layouts and auto-activation of independent room processors for each possible physical room as walls open and close. Control linking between Rane's Digital Remotes to wall open/close toggles and room volumes is exquisitely intuitive. Gain-share auto mix mics in combined rooms and separate the mix automatically as walls close. Use Rane's AM2 Automixer to gain-share with both in-room mics and wireless mics when cascaded into a HAL's room combine processor. This means AM2 mixers can be hot-swapped between locations for quick set up for head table discussions. Control links to Digital Remotes also combine and separate automatically as wall states change. No presets required. Easily change signal processing settings as walls open and close, automatically with Rane IR2 Infrared Wall Sensors.

Halogen Room Combine Processor A

Acoustic Echo Cancellation (AEC) with the EXP7x

EXP7x front

The Rane EXP7x Expander for the HAL1x provides 8 channels of full-featured, drag and drop Acoustic Echo Cancellation (AEC). Each channel of AEC can be added to any HAL1x system input and route to any Halogen DSP block, including the gain-sharing automixer, manual mixer, regular Room Combine block, and Conference Room Combine block. The Rane EXP7x in combination with HAL1x and Halogen software provides a conferencing solution including far more than high-performance AEC.

Processing blocks to enhance the AEC system solution

  • Revolutionary Conference Room Combine block with intrinsic support for conferencing
    • Independent Far End mixers and AEC Reference output per room.
    • Far End gain-sharing mixer inputs and AEC reference feeds automatically change with each room combination.
  • Conference Switchboard DSP Router
    • Multichannel and Tracking processing blocks mirror local room processing in the AEC Reference signal path.
    • Included are the Multichannel Shelving Filter, Multichannel PEQ, Tracking Ambient Noise Compensation and Tracking Side-chain Compressor.

Each AEC channel includes:

  • Mic and Reference Inputs with Level control & metering.
  • AEC on/off, plus adjustable AEC Threshold.
  • Soft / loud talker AGC & 5-band parametric EQ, plus high- and low-cut filters.
  • Full bandwidth AEC with adjustable non-linear processing.
  • Ambient Noise Reduction (dynamic & steady-state) & howling prevention.
  • Complete metering: Input, Reference, Echo Return Loss (ERL), Echo Return Loss Enhancement (ERLE) & Total Echo Return Loss (TER).
  • 20 to 20 kHz Bandwidth, 300 ms tail length.
  • <17 ms propagation delay, 100 dB/sec convergence rate.

Halogen AEC parent / child blocks

Because EXP7x AEC channels are not associated with a particular hardware input, preset recall can re-assign an AEC resource across inputs / rooms as required. Drag and drop AEC supports the typical one-AEC-per-microphone configuration. With optimum acoustics, mic and loudspeaker placement, or with rarely used mics (such as audience mics) it allows mixing more than one mic into a single AEC channel, significantly reducing cost.

What's unique about HAL’s AEC?

  • Flexible drag-and-drop AEC placement.
    • Use it where you need it, on any HAL System input.
    • Re-route AEC resources with presets: re-use AEC across rooms.
  • Intrinsic support for conferencing with advanced supporting processing blocks:
    • Conference Room Combine block.
    • Conference Switchboard.
  • Multi-channel processing blocks mirror room processing in the reference signal path.
  • High-Level, inherent conferencing support through.

Halogen AEC Conference Matrix Mixer

The Conference Switchboard block supports dynamic routing of Far End Audio sources. This block is useful when more than one room must share a single VoIP or Video Conference resource. It’s also useful when a room needs to access one or more remote rooms on a campus in order to include them in a conference. In some cases a combination of these scenarios is required.

The function of the Conference Switchboard could be accomplished using a standard matrix mixer, but that would require a user to avoid disallowed routing (like 1:1 or 2:2 etc.), and ensure that To and From Far End pairs are correctly wired. This Conference Switchboard simplifies the process.

Halogen AEC Room Combine Block

Conference Room Combine Block

Conferencing in a room combine environment is a complex task without a specialized Room Combine Processor designed to handle room mix, far-end mix and AEC reference routing. Halogen's unique ability to do conferencing within a room combine scenario without complex wiring and routing makes it easy.

Multi-Channel Processing Blocks

In order to get the best performance from an AEC application, the same signal processing parameters used to feed a room loudspeaker must be applied to the AEC reference signal as well. To simplify this process, special blocks that mirror the processing for room and reference channels include:

  • Tracking Compressor
  • Tracking ANC
  • Multi-Channel PEQ
  • Multi-Channel Shelf.

Halogen AEC Processing Workspace

Halogen provides a highly integrated Conference Room Combine block that greatly simplifies conferencing in a room combine configuration. The block combines room sources, selects a proper reference, and sends audio to appropriate locations as rooms combine. It also provides support for maintaining a proper AEC Reference with local Voice Lift.

This block supports unique mixes from Record and Room outputs. An independent AEC Reference Output is provided for each room to accommodate various microphone locations and unique room processing outside the Conference Room Combine block. Also inherently provided in this block are support for background music selection and paging per room.

AEC Meeting Table

A boardroom application has a number of microphones with overhead sound reinforcement. In this type of system, sound reinforcement is typically strengthened and delay compensation added as a loudspeaker gets further from the original source.

In this scenario, if room acoustics are good, it is possible to use a single AEC processing block for more than one microphone by combining microphones in a common reinforcement zone. The drag-and-drop flexibility of EXP7x AEC blocks lets you add AEC to any Halogen system input.

In the drawing below, the red lines are the daisy-chained CAT5 expansion bus, the blue lines are CAT 5 to RADs from the HAL1x and EXP1x RAD Expander, and the yellow lines are shielded mic cable to analog inputs on the RADs, EXP5x Input Expander, and HAL1x.

HAL1 Multiprocessor

HAL1 front

HAL1 rear

The original HAL1 and EXP1 have been replaced with the HAL1x and EXP1x. Only the HAL1x can be expanded with EXP“x” units. The HAL1 expansion bus uses firewire, the HAL1x expansion bus uses shielded CAT 5e.

  • Same specs as HAL1x except for the Expansion Bus and total I/O.
  • Expansion Bus connects up to four optional EXP1 units (red area)
    • Firewire IEEE 1394a 6-pin connectors
    • 64 x 32 audio channels

EXP1 Expander for HAL1

EXP1 front

EXP1 rear

  • Same specs as EXP1x except for the Expansion Bus.
  • Expansion Bus connects up to four more EXP1 units to a HAL1
    • FireWire IEEE 1394a 6-pin connectors
    • One non-locking 1-meter FireWire cable included

HAL3 Multiprocessor

HAL3 front

HAL3 rear

The original HAL3 has been replaced with the HAL3s. The HAL3s does everything the HAL3 does, with a new analog Mic/Line-Plus input stage, one DR port becomes a RAD port to make the HAL3s a 6-input, 10-output DSP (the HAL3 was 4 x 8), and the dynamic range is improved 10 dB, all at the same price as the HAL3 (contact your dealer, representative or distributor).

A HAL3 Multiprocessor supports 4 in x 8 out audio, with 2 in x 6 out on balanced analog connections, and another 2 in x 2 out digitally through a RAD. The two analog Inputs are Line / Line-Plus capable. In addition to supporting balanced line inputs, this configuration allows a stereo pair connection to an input, converting to a single L+R mono signal.

  • Same specs as the HAL3s except for inputs and outputs
  • 2 analog Line-Plus Inputs on Euroblock connectors (green area)
    • *“Line-Plus” Inputs accept a balanced line, or mono left & right unbalanced lines, configured in Halogen software.
  • 6 analog balanced line outputs on Euroblock connectors (orange area)
  • 1 RAD Port, 2 in x 2 out plus control channel (blue areas)
  • 4 Digital Remote Ports (brown and blue areas) [DR can connect to RAD port]
