Audio amplifier Omnitronic 80709742 Performance/stage Black

The Omnitronic MPZ-350.6P ELA mixer amplifier is a 19" rack-mount unit designed for both mobile and permanent ELA (Emergency Loudspeaker/Distributed) sound reinforcement installations. It provides outputs for 70 V and 100 V transformer lines as well as low-impedance 4–16 Ω speakers, six mixable inputs (up to 3 microphones and 3 line-level devices), a line output for connecting an external device, and an integrated MP3 player with USB and SD card playback and infrared remote control.

Advantages

The MPZ-350.6P combines flexible loudspeaker output options (70 V, 100 V and 4–16 Ω), six mixable inputs and six switchable zone outputs for separate control of speaker groups. The front-panel microphone input features an adjustable priority function with automatic attenuation of other signals and a gong trigger for announcements. A front-panel MP3 player with blue-backlit LCD, USB and SD card slots allows direct playback from storage media.

How to use

Install the unit in a 19" rack or place it on a shelf. Connect speakers to the appropriate output terminals (70 V/100 V for constant-voltage lines or 4–16 Ω for low-impedance speakers) and secure wiring with the clamp terminals. Make signal connections for up to three microphones and three line-level sources to the mixable inputs. Use the front-panel switches to activate individual zones and adjust levels. Load MP3 files onto a USB stick or SD card and use the front-panel controls or included infrared remote to browse and play tracks. Use the microphone priority switch when announcements are required to reduce background audio automatically.

Recommendations

Use 70 V or 100 V outputs for distributed speaker systems to simplify long-cable runs and reduce power loss. Match speaker transformer taps to the amplifier's output power per zone. When using the priority mic for announcements, set the attenuation level so speech intelligibility is maintained while background music is reduced.
