AM2 Automixer

AM2 Automixer


  • Gain-Sharing Automatic Mic Mixing:
    • Eight XLR Inputs with Level controls & Sig/OL indicators.
    • Each can be Mic, Mic with 48V phantom, or Line-level.
  • Add up to 64 more gain-sharing inputs by cascading AM2 Automixers.
  • Add other audio sources, line inputs and remote controls by connecting to HAL system.

Outputs (all mono):

  • XLR Main with Mic/Line switch, Level control & Sig/OL.
  • Rane RAD and Cascade IN RJ-45 Ports:
    • Cascade In Port connects up to seven additional Rane AM2 mixers, (eight units total)
    • RAD Port may send Output to HAL (DSP/control). It is possible to cascade the AM2 mix into Halogen's Gain-Sharing Auto Mixer or Room Combine Processor DSP, so that all mics connected to HAL may gain-share.

AM2 Automixer

The Rane AM2 is both an 8 channel, gain-sharing automatic mic mixer and simultaneously a Rane RAD. Use it as a standalone mic-only mixer, add more gain-shared mics using up to seven additional AM2 Automixers, and/or use the RAD Port to transport the mic mix to Rane's HAL system.

Each of the eight XLR Mic Inputs offers front panel input Level controls feeding a gain-sharing automatic mixer. Rear panel, 3-position selectors support dynamic mics (no phantom power), condenser mics (48 V), or line input optimized for wireless receiver outputs (+10 dBu max). All Level controls come with front panel signal and overload indicators.

The AM2 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 the gain-sharing algorithm.

The XLR Main Output can be set to mic- or line-level to feed a mic snake or a +20 dBu max balanced input. When an AM2 is used standalone, both the XLR Output and the RAD Port output audio are affected by the front panel Output Level control. When the AM2’s Cascade Output feeds a downstream Rane AM2, the front panel Output Level control only affects the XLR Output.

The USB port is solely used as a firmware update port if future updates are needed. If you need USB or analog audio in or out, cascade an AM2 with a HAL system.

The RAD Port sends the AM2 Output mix to a Rane HAL System. Cascade IN accepts audio and data from an upstream AM2’s Cascade OUT. This adds eight more mic channels to the initial AM 2 creating a 16-channel gain-sharing automix. A maximum of eight AM2s can be cascaded, offering up to 64 gain-shared mics. Simply connect Cascade OUT ports to Cascade IN ports and the RAD Port to the HAL. Both the Cascade IN port and the Cascade OUT/RAD Port have status indicators to aid setup and troubleshooting. Rear panel Fault, Locate, and Power indicators inform head-scratchers of device errors, the AM2’s physical location and AC power status. Duplicate Locate and Power indicators on the front help installers physically locate and verify AC power to the AM2.

Universal IEC power on the rear supports 100 to 240 VAC and 50/60 Hz. The AM2 is UL Listed and CE Certified.

AM2 and AM2 System

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 minimal audio experience. Pitfalls abound when interconnecting the system, and managing multi-microphone gain before feedback, mixing and volume. Enter the Rane AM2.

Podium and lavalier conflictThe AM2 makes it easy for an inexperienced operator to quickly set up and manage multiple microphones for presentations involving up to eight participants with wired or wireless microphones. The AM2 offers a professional integrated solution providing superior automatic gain before feedback while eliminating operator error with its 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 talkers (noncoherent signals), and 6 dB per doubling for the same talker who is directly between two mics (coherent signals). Thus, gain-sharing solves the common problem of a wandering speaker on a wireless lavalier, speaking into a live mic intended for others. The AM2 handles the gain of both inputs without risking feedback, amazingly well.

When using AM2 with the Rane HAL (sold separately), connection is made using RAD port. The AM2 is detected as a RAD device and may be used as a single mixer or cascaded into Gain-sharing Auto Mixer block.
