MZA-16 Digital 16-Channel/8-Zone Power Amplifier with S/PDIF Input and Subwoofer Output

INTRODUCTION The Soundavo MZA-16 is the 16 channel power amplifiers are ideal for use in adding additional power in distributed audio systems or combining with the commercial sound installation and whole-home audio applications. It designed in great features such as stereo/bridge mode operation, global and independent one triggering, subwoofer line output for each zone with crossover built-in and two Bus Inputs/Outputs. FEATURES - 16 channels, 8 independent zones - 8 Subwoofer Outputs with Adjustable Crossovers per Zone - Speaker Level Subwoofer Capability, allows you to power a passive subwoofer over a speaker wire, eliminating the need for a separate subwoofer amplifier - 50W per channel, bridged 160W per Zone - On/Off buttons for each zone on the front panel, for easy set the mute status on the specific zone and energy efficiency - Zones are bridgeable to create flexible power configurations  - Two common or BUS inputs that receives audio signals from standard line-level audio sources and sends them to any or all channels - S/PDIF Optical Bus Input  - High efficiency, cool running digital amplification - Global Trigger -Input/output triggers on/off for all zones on the bus input - Zone Trigger -Independent trigger input/output on each zone for on/off - Can be converted easily between rack-mount and tabletop configurations - Heavy-duty steel chassis with black glass and brushed aluminum faceplate - Anti-Clipping Protection Circuitry & Fault Safety Circuitry - The Ground Lift helps reduce or eliminates the ground-related noises - Versatile Installation: Designed for both residential and commercial applications, the MZA-16 can be installed in various setups, including home theaters, distributed audio systems, and more.

THERMAL PROTECTION The MZA-16 amplifiers are designed with special circuitry to safeguard the amplifier under a thermal overload condition. Thermal protection mode will only engage when the unit has been run at high volume for extended periods of time without adequate ventilation and/or when speaker impedances are below the minimum levels for the amplifier. In thermal protection mode the amplifier will automatically stop output. If this fault occurs, turn o the amplifier, and check that the speaker impedance rating is above the minimum rating. Also check for adequate ventilation around the amplifier and make adjustments if necessary. Once the unit has cooled to sage operating temperatures, the amplifier may be powered back on. PROTECTION CIRCUITRY Special circuitry has been designed into the amplifier to safeguard under a short-circuit condition. A faulty speaker can be also cause a short circuit condition, if by accident the speaker wires cross (touch each other), No sound or distortion will come from any speakers attached to the faulted wires until you correct the fault. If this fault condition occurs, turn off the amplifier and check speakers for short circuit conditions when appropriate.
