The CX-MP912 is a professional 4×4 matrix mixer amplifier designed for background music, paging, and multi-zone public address applications. It is suitable for schools, factories, hospitals, shops, offices, hotels, supermarkets, commercial buildings, and small to medium PA installations. With 4 separate amplifier outputs, each channel provides 120W RMS power, making it suitable for projects that require stronger zone-based audio output.

This amplifier supports 5 AUX inputs, 3 balanced microphone inputs with phantom power, 4 remote paging stations, USB/Bluetooth audio input, TEL input, built-in chime, and one-touch emergency alarm. Each AUX and microphone input has independent volume, bass, and treble control for easy sound adjustment. It also supports 70V/100V and 4–16Ω speaker output, allowing flexible connection for both long-distance PA systems and low-impedance speaker installations.
