The Matrix Mixer block mixes multiple input signals into a variety of output channels.
note: You may be wondering if you'll need to use the Matrix Mixer block to set up paging, complex zoning, and room combine. The answer is an emphatic NO! Most systems (including Rane’s DragNet products) use matrix mixers for these applications. Perhaps you are familiar with the complex features of the RPM’s Mixer/Router/Ducker block. Matrix mixers (along with presets) have historically been the Swiss Army Knife of audio DSP (if your Swiss Army Knife contained 256 identical blades). Zoning, paging, and room combine required a giant matrix with inputs for every background music source, paging station, microphone, and line input in the system. Developing the audio system involved taking snapshots of the matrix mixer as configured for every possible permutation of background music selection, room combination, and page source to destination. As the number of inputs, zones, and configurable walls increased, the number of crosspoints in the matrix and presets in the system grew exponentially. The HAL System removes this burden by providing more powerful blocks and subsystems that are already programmed with the logic required to perform complex paging, zoning, and room combine processing. If you’re designing a powerful, modern audio system, leave that Swiss Army Knife in your pocket and take a look at the Zone Processor, Room Combine Processor, Distributed Program Bus, Paging Station and Paging Zone blocks. These blocks will get you much farther in a fraction of the time.
Use the Matrix Mixer block to mix multiple input signals into a variety of output channels.
From this dialog box, you can do the following:
note: These signal indicators are actually meters, therefore they are subject to the same 16 active meter limit as all other meters.
|Input nodes||Connection points for wiring input to the Matrix Mixer block|
|Output nodes||Connection points for wiring the Matrix Mixer input to specific outputs|
|<Add> nodes||Click to add another Input or Output node, or wire to the <Add> node to automatically create a new channel.|
(Hover over the thumbnail below to view the properties dialog box.)
|Crosspoint||Each square in the matrix where an input column and output row intersect|
Crosspoint Level (Manual and Linkable Control)
|Control the relative volume of an input signal. Each input is attenuated by the level of the control in the input column and then they are all summed together before reaching the output level. Provide end users with control over input volume by linking this Level Control to the Level Control of a DR1 or DR3.|
|Crosspoint Enable Checkbox||Select to include the input in the mix.|
|Input Mute (Manual and Linkable Control)||Mute this input. Provide end users with mute control by linking this Toggle Control to the Toggle Control of a DR2, DR3, or Logic In.|
|Input Signal||Lights when a signal is detected on this input, turns red if signal overload occurs.|
|Output Level (Manual and Linkable Control)||Control the volume of the entire mix for that output. Provide end users with control over the output volume by linking this Level Control to the Level Control of a DR1 or DR3. Change the range by clicking the Minimum or Maximum value (below the slider) and then typing new values in the edit box that appears.|
|Output Mute (Manual and Linkable Control)||Mute the mix output without changing the output level control. Provide end users with output mute control by linking this Toggle Control to the Toggle Control of a DR2, DR3, or Logic In.|
|Output Off @ Min Checkbox||When checked, causes the audio to mute completely when dialed to the low end of its range.|
|Overall Mute Checkbox||Mute all outputs from the Matrix Mixer block. Manual control only.|
