CMX PA-6120MX – 6 Zone Matrix Amplifier
Professional Enterprise 6-Zone Audio Matrix Mixer Amplifier with 6 × 120W (720W RMS Total) Class-D Power Amplification, 6-Channel Matrix Routing, Built-In Bluetooth/USB/SD/FM Player, Dual 100V & 8Ω Simultaneous Outputs & CAT6 Remote Control Architecture
The CMX PA-6120MX is an enterprise-grade 6-zone commercial audio matrix mixer amplifier engineered for comprehensive multi-room public address (PA) and background music (BGM) distribution in hospitality, education, sports, corporate, and commercial facilities. Featuring six discrete Class-D power amplifier modules delivering 120W RMS per channel (6 × 120W, 720W RMS total), the PA-6120MX combines a flexible 6-channel audio matrix with high-efficiency multi-zone power amplification in a single standardized 19-inch 2U rack-mount chassis. Any input source—including the integrated Bluetooth/USB/SD/FM multimedia player, three balanced combo XLR mic/line inputs with switchable 48V phantom power, and auxiliary RCA inputs—can be matrix-routed to any of the six output zones independently. With simultaneous support for 100V constant voltage speaker lines and 8–16Ω low-impedance taps, front-panel headphone zone monitoring, connectivity for up to 6 remote CAT6 paging microphones (PA-6000RM) and 6 in-room remote wall panels (PA-6000WP), priority VOX override, and third-party 24V emergency mute integration, the PA-6120MX represents the premier amplification hub for multi-zone commercial audio.

Frequently Asked Questions
What makes the CMX PA-6120MX different from a standard multi-zone amplifier?
Unlike standard amplifiers that only broadcast a single audio source to multiple zones with volume attenuators, the PA-6120MX is a true 6-channel audio matrix amplifier. Powered by six independent 120W Class-D amplifier channels, it allows six completely different audio sources to play in six separate zones simultaneously.
Can the PA-6120MX power both 100V distributed speakers and low-impedance speakers?
Yes. Each of the six discrete output zones provides dedicated terminals for both 100V commercial distributed lines (ideal for numerous ceiling or wall speakers over long cable runs) and 8–16Ω low-impedance loads for high-fidelity foreground speakers.
How do remote wall panels and paging microphones connect to the amplifier?
The amplifier features dual RJ45 ports on the rear panel. Using standard straight CAT6 network cabling, you can connect up to 6 remote zone-paging microphones (PA-6000RM) and up to 6 in-room remote wall panels (PA-6000WP), allowing localized room source selection, volume control, and in-room Bluetooth streaming up to 200 meters away.
Can sound engineers monitor individual zone audio from the amplifier front panel?
Yes. The PA-6120MX includes a dedicated front-panel headphone monitoring jack with an independent volume potentiometer and zone selector switch, allowing technicians to verify audio quality and source routing in any zone locally.
Does the PA-6120MX support fire alarm emergency voice evacuation integration?
Yes. It includes a 24V emergency mute phoenix connector that interfaces directly with building fire alarm panels, instantly muting background music and activating built-in pre-recorded emergency evacuation or alert broadcasts.
