Our four-channel independent matrix audio solution delivers targeted audio routing for diverse meeting scenarios. It supports partitioned multi-functional halls to isolate audio signals between separated rooms and eliminate cross-room sound leakage. Built-in route avoidance technology automatically mutes nearby speakers to cut acoustic feedback for fixed meeting layouts. Dual-channel partitioning handles hybrid online-offline conferences by separating local reinforcement and remote transmission signals. For large keynote events, it creates two independent audio paths to control latency under 30ms, removing echoing discomfort for speakers. Powered by professional DSP processing, this all-in-one matrix system resolves core audio pain points across split meeting rooms, roundtable hybrid sessions and large-scale presentations.
