Amplificador de áudio Omnitronic 80709782 180 W classe A/B preto

The Omnitronic MPVZ-180.6P ELA mixing amplifier is a 19" format unit designed for mobile and fixed public address and sound reinforcement systems. It provides flexible outputs for 70 V and 100 V constant-voltage ELA loudspeakers as well as conventional 4–16 Ω speakers, and offers six mixable inputs for up to three microphones and three line-level sources. The front panel includes an MP3 player with USB port and SD card slot plus a blue backlit LCD display, and the unit integrates protection features including a fan, switch-on delay, overvoltage and short-circuit protection.

Advantages

The MPVZ-180.6P combines multiple speaker output options (70 V / 100 V and 4–16 Ω) with six selectable input channels, allowing connection of microphones and line-level devices. Six zone outputs with front-panel 5-step volume controls provide independent level adjustment per zone. Built-in MP3 playback via USB/SD with remote control and an adjustable microphone priority with gong function add operational flexibility. Protective features and thermal management improve operational reliability in continuous use.

How to use

Install the unit in a standard 19" rack or place it on a flat surface suitable for rack equipment. Connect loudspeakers to the appropriate output terminals depending on whether you use constant-voltage (70/100 V) or low-impedance (4–16 Ω) speakers. Hook up microphones and line-level sources to the six input channels and set blend and levels from the front panel. Use the zone outputs to route audio to different zones and adjust each zone's level using the 5-step controls. Play audio files from a USB stick or SD card via the built-in MP3 player or use the line output to feed another device.

Recommendations

For reliable long-term operation, ensure adequate rack ventilation and avoid operating the amplifier at maximum output continuously. Use the microphone priority for important announcements and engage the gong sparingly to maintain clarity. When connecting multiple speakers, verify wiring and impedance matching to prevent overloading the amplifier.
