The MZA-7010 is the most advanced Multi-Zone Amplifier available on the market today. Designed for harsh environments with unfriendly electrical situations such as rail, marine, bus, and other transit applications, this industrial unit is ready for any public-address application and prepared to withstand the toughest challenges.

Built upon twenty years of successful deployments within the metropolitan transit space, this next generation digital device brings your installation or application up to the 21st century with a fully forward-looking, yet backward-compatible solution.

A robust and efficient CLASS-D amplifier platform, powered by Texas Instruments PurePath™ technology, the MZA-7010 provides state-of-the-art audio quality for any program material and will drive both 70V and direct connection loudspeaker loads. With flexible audio and control inputs, it provides four independent zone outputs that will interface to most any application.

Built to last, it incorporates a well-defended wide-range DC input power system, over-engineered ESD protection on all connections, transformer input and output isolation for ground loop prevention, and is protected by an aluminum-alloy extruded enclosure that is IP67 rated and meets IEC 60068-2 environmental standards.

Advanced features include 24-bit analog-to-digital conversion, 32-bit digital signal processing, digital filtering, automatic adjustment of announcement level referenced to ambient noise, dynamic fault protection, and advanced diagnostics such as real-time signal level, supply voltage, supply current, and load impedance monitoring.

Equipped with advanced communications capabilities, the MZA-7010 includes a high speed Ethernet interface and Bluetooth 4.0 interface; both protected by industry standard encryption and advanced security measures. The Ethernet link can be used for control, diagnostics and streaming audio to the device. The Bluetooth interface securely connects to our configuration and diagnostics mobile application (iOS and Android platforms) for real time signal metering, control status reporting, dynamic level adjustment, loudspeaker configuration, and system diagnostics.
