Audio amplifier Omnitronic 80709645 Performance/stage Black

The Omnitronic 80709645 Performance/stage Black is a two-channel audio amplifier with a Class A/B output stage designed for live sound and fixed installations. It delivers a peak power of 350 W per channel while maintaining a low Total Harmonic Distortion (THD) of 0.5%, offering clear reproduction of music and speech. The unit accepts a standard AC input of 230 V at 50 Hz and has compact rack-compatible dimensions of 483 mm (width) x 400 mm (depth) x 89 mm (height), allowing integration into equipment racks and stage setups.

Advantages

The amplifier combines a high peak power capability with a modest typical power consumption of 700 W, balancing performance and energy use. Clamp-style speaker terminals provide secure, tool-free speaker connections suitable for rapid setup and teardown. The Class A/B topology aims to deliver stable, low-distortion audio across a variety of source material, making the unit reliable for both program material and spoken word applications.

How to use

Install the amplifier in a standard 19-inch equipment rack or place it on a stable surface with adequate ventilation around the chassis. Connect audio sources using appropriate line-level outputs and set input gain controls to achieve the required signal level without clipping. Attach loudspeaker cables to the clamp terminals, ensuring correct polarity for each channel. Power the unit from a 230 V, 50 Hz mains supply and verify that the amplifier's thermal and protection indicators are normal before applying full signal levels.

Recommendations

For reliable operation, allow clearance for airflow and avoid enclosing the amplifier in unventilated cabinets. Use speaker wiring of sufficient gauge for the load and run test signals at moderate levels when confirming system gain structure. When used in live or installed systems, perform a soundcheck at performance levels to confirm headroom and to prevent clipping or overheating.
