Bose Professional AVM-1 Sense Microphone

The AVM-1 Sense Microphone from Bose Professional discreetly mounts flush into common ceiling surfaces and provides an analog output over a balanced audio connection. It's designed for use with the AutoVolume compensation feature offered in select Bose Professional sound processors. Used with AutoVolume, the microphone delivers a continuous ambient room noise reference, allowing the AutoVolume algorithm to adjust output zone levels automatically based on activity in the room.
