The BG-AU88-MA is a powerful DANTE-equipped audio mixer equipped with 4 microphone input channels, 6 line input channels, 10 line output channels, and a DANTE output. Packed with useful features like full-band Adaptive Echo Cancellation (AEC), Adaptive Noise Suppression (ANS), Automatic Gain Control (AGC), and auto-mixing, this audio processor outputs clear, clean, and detailed audio with a high signal-to-noise ratio.

Connectivity & Features

The BG-AU88-MA is compliant with HDMI 2.0b and can process HDMI audio. It also features an HDMI loop-out and supports HDMI audio embedding and de-embedding. This device also has a 48V phantom power supply for the four microphone input channels. The inclusion of a DANTE port enables connectivity for networked audio distribution systems.

Thanks to dynamic adaptive noise reduction technology, noise can be reduced at signal levels up to 18 dB, ensuring that sound is clear with less background hum and fuzz. Combined with Automatic Gain Control and Adaptive Echo Cancellation, the BG-AU88-MA is able to achieve a high signal-to-noise ratio.


Each of the analog I/O channels has a volume knob allowing operators to control volume independently for each channel. The auto-mixer function enables operators to set the priority order when multiple microphones are in use at the same time. The powerful suite of digital signal processing modules include a compressor,  expander, equalizer,  auto gain control, limiter, high pass filter, low pass filter, and delay for each channel of audio. Volume control, signal meter, and scene control functions round out this premium mixer’s robust set of features.

Operators also have the ability to switch to matrix routings when needed. The BG-AU88-MA is controlled  using the included software supporting Windows systems via the LAN connection. RS-232 serial control is also supported.
