AVM-1 sense microphone

The AVM-1 sense microphone mounts discreetly into ceilings and provides an analog output over a balanced audio connection. Designed for use with AutoVolume compensation, as featured in select Bose Professional sound processors, the microphone delivers a continuous ambient room noise reference. This allows the AutoVolume algorithm to adjust output zone levels automatically based on activity in the room.
