This 2-channel matrix mixer amplifier is an all-in-one audio solution engineered for flexible and scalable systems. It perfectly integrates a high-efficiency Class D amplifier with a intelligent matrix mixer. Delivering robust 2×120W / 2×240W power with selectable constant voltage/constant resistance operation, it features extensive I/O connectivity. The core matrix mixing capability allows for free signal routing, enabling independent or combined playback from multiple audio sources to different zones. With added remote paging and volume control, all packed into a compact 1U chassis, it stands as the ideal choice for background music, public address, and multimedia applications, ensuring precise audio management and reliable performance in complex scenarios.
