BZBGear BG-A88M 8x8 Digital Audio Processor

The A88M is the DSP for a conference room or a divisible space: eight balanced microphone or line inputs, eight balanced line outputs, and the processing that makes a room-mic system usable - acoustic echo cancellation, noise suppression, automatic gain control and an auto mixer that opens and closes channels on its own.

Conversion is 24-bit at 48 kHz, phantom power is +48 V, and maximum microphone gain is 40 dB. Eight programmable GPIO pins on a ten-pin Phoenix connector tie it into wall controls or a control system, alongside LAN and RS-232. The chassis is a 440 mm rack box drawing 9 watts.
