AM1 Automixer

AM1 Automixer

AM1 rear

The Rane AM1 is an Automixer with four gain-sharing XLR Mic/Phantom/Wireless Inputs, combined with a manual mixer with one RCA Line Input, one 3.5 mm Line Input with a USB charge port, USB Audio Input and Output, XLR Mix Output, RCA Record Output, and a Headphone Amp with source selector. It is cascadable to add more inputs with AM2 Automixers, and has a RAD Port connecting to CobraNet via Mongoose.

AM1 Automixer Inputs

The Rane AM1 is part gain-sharing automatic mic mixer, part manual line mixer, part USB audio I/O device, and simultaneously a Rane RAD.Use it as a standalone mic/line mixer, or add more gain-shared mics using up to seven Rane AM 2 Automixers (sold separately). Use the RAD Port to transport the main mix digitally via CAT 5 to either a Rane HAL's RAD Port, or to a Rane Mongoose to a CobraNet network.

Each of the four XLR Mic Inputs offers front panel input Level controls feeding a gain-sharing automatic mixer. Rear panel, 3-position switches for each Mic Input support dynamic mics (no phantom power), condenser mics (48 V), wireless receiver outputs (+10 dBu max). A front panel Mic Mix Level control adjusts the volume of all automixed mics.

The AM1 is optimized for automixing speech. The mic inputs have a fixed 100 Hz to 7 kHz bandpass filter to provide the best voice-only automatic mixing using a gain-sharing algorithm.

Three manually-mixed audio inputs provide a simple user interface and installation. The Aux 1 Input dual RCA and Aux 2 3.5 mm jacks are independently monoed, each with a front panel Level control. A dedicated USB Charge port adjacent to Aux 2 provides power to USB devices such as iPods or other USB-powered devices. The separate orange USB Audio Input also offers a front panel Level control for the 16-bit, 48 kHz digital audio that is monoed immediately upon entry.

Signal and Overload indicators monitor the Mic and Aux Inputs, the Mic Mix and the Main Mix. Indicators flank the corresponding Level controls.

The AM1 appears in Windows and Apple OS X computers as a standard USB Audio Device, immediately compatible with dozens of audio recording and playback audio applications. The AM1 registers with the OS as a 16-bit 48 kHz device for both incoming and outgoing audio. The USB Audio port doubles as a firmware update port if future updates become available.

The XLR Main Output can be set to Mic- or Line-level to feed a mic snake or a +20 dBu max balanced input. The front panel Output Level control affects the XLR Output and the RAD Port output. The analog RECORD RCA Outputs and the digital USB Audio output are both mono, pre-Output Level, containing the same mix as the Main Output.

AM1 Outputs

The RAD Port sends the AM1 output mix to either a Rane HAL's RAD Port for further signal processing and control, or to a Mongoose for routing to a CobraNet network. The Cascade IN accepts audio and data from a Rane AM2’s Cascade OUT. This adds the AM2’s eight mic channels to the AM 1, creating a 12 channel gain-sharing automix. Up to seven AM2s can be cascaded to a single AM1, offering up to 60 gain-shared mics. Both the RAD and the Cascade IN port have status indicators to aid setup and troubleshooting.

Rear panel Fault, Locate, USB and Power indicators inform head-scratchers of device errors, the AM1’s physical location, positive USB audio device OS registration and AC power status.

A front panel pre-Output Selector permits headphone cueing so users can verify input and output operation before bringing new sources into the live Output mix. Both ¼" & 3.5 mm headphone jacks with a Level control are provided. Duplicate Locate and Power indicators are on the front and rear.

Universal IEC power on the rear supports 100 to 240 VAC and 50/60 Hz. The AM1 is UL Listed and CE Certified.

Applications: AV Rental Systems • Hotels • Auditoriums • School AV Nerds • Conference Centers • Panel Discussions • Houses of Worship • Podcasting

Facilities and rental agencies are called upon to provide either equipment, or equipment and operators, for meetings or conferences needing A/V support. The equipment providers must ensure audio quality throughout the event to get repeat business. However, the provided equipment may be operated by presenters who have no audio experience. If an operator is sent with the equipment to set up and manage the system during the presentation, that operator may have little audio experience. Pitfalls abound when interconnecting the system, and managing multi-microphone gain before feedback, mixing and volume. Handling iPod and laptop playback and/or recording adds even more complexity. Enter the Rane AM1.

The AM1 makes it easy for an inexperienced operator to quickly set up and manage audio for a multimedia presentation involving up to four participants with microphones (wired or wireless) and several program audio sources (e.g., DVD, Laptop, MP3 player). The AM1 offers a professional integrated solution that provides superior automatic gain before feedback while eliminating operator error with simple controls. The microphone gain-sharing algorithm automatically and appropriately attenuates mics not in use while maintaining the 3 dB per doubling of mics for different (noncoherent) talkers, and 6 dB per doubling for the same (coherent) talker who is directly between two mics. Appropriately, line audio sources are manually mixed since there is no acoustic feedback potential. The AM1’s flexible line input combination of RCA, 3.5 mm and separate USB Charge and Audio I/O ports makes integration and cabling easy. And since the USB Audio port can simultaneously playback audio and record the AM1’s output, the same laptop can be a source and a recording device to document AV meetings, presentations, trainings, and family karaoke nights for AV contractor employees
