## Long description

The Omnitronic 80709781 Performance/stage Black audio amplifier is a two-channel class A/B power amplifier designed for stage and installed-sound applications. It delivers up to 180 W peak per channel with low Total Harmonic Distortion (THD) of 0.5%, offering a clear and controlled output suitable for passive loudspeakers. The amplifier accepts standard AC mains input and is built in a compact, rack-compatible chassis that fits typical 19-inch installations.
Advantages
The class A/B topology balances efficiency and audio fidelity, reducing audible distortion while providing reliable power for live or fixed installations. Low THD ensures accurate reproduction of source material, and the clamp-style speaker terminals enable quick and secure speaker connections. Compact physical dimensions allow integration into crowded rack systems or small staging setups, and the straightforward AC power requirements simplify deployment in common venue electrical environments.
Suitable for
Small to medium live sound systems and stage monitors
Fixed installations in bars, halls or small venues
Public address systems with passive loudspeakers
Portable setups requiring rack-mountable amplification

How to use
Place the amplifier in a suitable rack or on a stable surface with adequate ventilation around the chassis. Connect audio sources to the amplifier inputs following the input labeling, then connect passive loudspeakers to the clamp terminals making sure to observe correct polarity. Before applying mains power, set gain controls to a low position and power up the unit. Gradually increase input levels while monitoring speaker response to avoid clipping or overload. Allow the unit to cool between extended high-power sessions.
Usage recommendations
Use speaker cables of appropriate gauge for the installed load and keep connection lengths as short as practical to reduce power loss. Operate the amplifier within rated mains and ventilation conditions, and avoid exposing the unit to moisture or excessive heat. Periodically check terminal connections and mounting hardware to maintain secure operation in mobile or stage environments.
