Audio amplifier Omnitronic 80709621 Performance/stage Black

The Omnitronic 80709621 Performance/stage Black audio amplifier is a compact Class A/B amplifier designed for live performance and stage use. It delivers up to 120 W peak power per channel with low total harmonic distortion (0.5%), providing clear reproduction of musical and spoken material. The unit accepts 230 V AC at 50 Hz mains supply and offers clamp-type speaker terminals for secure wiring. Its slim 483 mm x 400 mm x 89 mm chassis is rack-friendly and intended for installation in compact stage and PA setups.

Advantages

This amplifier combines Class A/B circuitry with a stated low THD of 0.5% to balance sound quality and efficiency. Peak output of 120 W per channel gives sufficient headroom for small to medium performance venues while the clamp speaker terminals ensure reliable connections under frequent setup and teardown. The moderate typical power consumption of 240 W makes it suitable for venues where mains capacity must be considered. The physical dimensions are optimized for rack mounting or placement in limited-depth equipment racks.

How to use

Install the amplifier in a standard 19-inch equipment rack or place it on a stable shelf with adequate ventilation. Connect the mains cable to a 230 V AC, 50 Hz outlet and ensure proper grounding. Wire loudspeakers to the clamp terminals according to the speaker impedance and channel assignment, and connect the audio source or mixer outputs to the amplifier inputs using suitable cables. Power the unit on and set input gain and system-level controls to match the connected loudspeakers and room acoustics. Monitor levels to avoid clipping and to maintain the amplifier within recommended operating parameters.

Recommendations

Allow sufficient airflow around the amplifier and avoid enclosing it in tight spaces during operation. Verify speaker impedance compatibility and avoid driving the amplifier into prolonged clipping. For stage and performance environments, use secure cable management and check connections before each use to maintain reliable operation.
