Description
MU-1212 – 12-Channel Digital Audio Processor with USB Sound Card and Central Control
MU-1212 is a high-performance 12-channel digital audio processor designed for professional AV installations in conference rooms, educational spaces, exhibition halls, and commercial environments. It supports 12 analog inputs and 12 outputs, delivering high-quality audio processing with low distortion and wide frequency response. Powered by the ADI SHARC 21489 processor, MU-1212 features advanced DSP algorithms including echo cancellation (AEC), feedback suppression (AFC), noise suppression (ANS), noise gain compensation (ANC), automatic mixing (AMC), and ducker.
The built-in 1x1 USB sound card enables music playback, recording, and integration with video conferencing platforms. MU-1212 supports camera tracking, includes a 12-band parametric EQ, and offers centralized AV system control via RS232, RS485, and UDP. Users can manage up to 30 devices from a single customizable interface.
