MU-44 – 4-Channel DSP Processor with USB and Central Control
MU-44 is a professional 4-channel DSP audio processor designed for AV systems in conference rooms, exhibition halls, multi-purpose venues, and sports facilities. It offers advanced audio processing features such as independent echo cancellation (AEC), feedback suppression (AFC), noise suppression (ANS), and an 8-band parametric equalizer with five filter types. With a built-in 2x2 USB audio interface, MU-44 supports music playback, recording, and integration with popular video conferencing platforms.
The processor includes central control functionality via RS232, RS485, and UDP protocols, enabling comprehensive management of power, signal switching, environmental and audio control from a single interface. MU-44 also supports user interface customization and management of up to 30 devices from one application.
