M20 Mic Array Module for AI Translation Booths

For two-way translation systems, the M20 keeps both speakers apart. Independent directional channels perform A/B role voice separation, so each side of a booth is captured on its own audio stream for reliable machine translation.

Built for Translation Workflows

A/B Role Voice Separation: left and right talkers mapped to separate pickup lobes.
3m Directional Pickup: clear voice at normal speaking distance with ≥12dB off-angle rejection.
Dual Output Interfaces: USB Type-C digital and 3.5mm analog audio for host flexibility.
DSP Voice Enhancement: beamforming, AGC and ≥20dB noise suppression on-device.
