Audio amplifier Omnitronic 80709722 Performance/stage Black

The Omnitronic MPZ-180.6P ELA mixer amplifier is a 19" rack-mountable unit designed for public address and distributed (70/100 V) sound reinforcement systems. It provides six mixable inputs that accept up to three microphones and three line-level sources, six independently switchable zone outputs for controlling ELA speaker lines, and dedicated outputs for 70 V, 100 V or 4–16 Ω loudspeakers. The unit also includes an integrated MP3 player with USB port and SD card slot, a blue backlit LCD and infrared remote control for playback.

Advantages

The MPZ-180.6P combines flexible input routing and six zone outputs in a compact 19" format suitable for both mobile and permanent installations. Front-panel microphone priority with adjustable attenuation and a built-in gong allow immediate announcement capability, while the line output enables connection of an external mixing console or recorder. Multiple speaker output options (70 V/100 V/4–16 Ω) cover common ELA installation requirements.

How to use

Mount the amplifier in a standard 19" rack and connect mains power according to the local voltage and safety regulations. Connect microphones and line-level sources to the respective inputs and route speaker lines to the appropriate 70 V/100 V or low-impedance outputs depending on the speaker system. Use the front-panel controls to mix inputs and switch zone outputs on or off as required. Load audio files to a USB stick or SD card to play music via the built-in MP3 player, or control playback with the supplied infrared remote.

Recommendations

For stable ELA performance, calculate speaker line loads before connection and use the specified 70 V or 100 V taps to avoid overloading the amplifier. When using the mic priority function, set attenuation to a level that ensures announcements are audible without clipping other signals.
