Engineered for scalable sound reinforcement, this 2-Channel Matrix Mixer Amplifier combines a high-efficiency Class D power engine with a smart digital audio matrix into a single 1U enclosure. Offering 2×120W or 2×240W output with selectable high-impedance (constant voltage) / low-impedance operation, it features comprehensive I/O connectivity. The flexible matrix routing allows independent or combined signal distribution from multiple sources to distinct zones. Complete with remote paging and wall-panel volume extension, it delivers precise audio management for background music, public address, and commercial AV installations.
