Description
Bose Professional AVM-1 Sense Microphone
Bose Professional AVM-1 is a sense microphone designed to provide ambient noise reference for commercial sound systems. It enables automatic level compensation by supplying continuous room noise data to compatible Bose Professional sound processors. This makes it ideal for environments where consistent audio levels are required despite changing ambient conditions.
The microphone outputs an analog balanced signal and operates using phantom power from the connected processor. Its omnidirectional condenser capsule captures ambient sound evenly across the room. The design supports long cable runs for flexible placement within distributed audio systems.
The AVM-1 supports automated system performance by enabling AutoVolume processing in compatible processors. Its low-profile form factor allows discreet installation in ceiling spaces. The microphone is intended for permanent commercial installations requiring adaptive sound level control.
