Audio amplifier Omnitronic 80709650 Performance/stage Black

The Omnitronic 80709650 Performance/stage audio amplifier is a compact Class A/B amplifier designed for live performance and stage applications. It delivers a peak power of 500 W per channel with a rated Total Harmonic Distortion (THD) of 0.5%, providing clear amplification for driven speaker systems. The unit uses clamp-style speaker terminals for secure cable connections and is built to fit into standard 19" racks with a shallow 89 mm front height and compact depth, making it suitable for mobile and fixed installations.

Advantages

The amplifier combines Class A/B circuitry with a high peak output, offering a balance between sound quality and output capability while keeping THD low at 0.5%. Its clamp terminals simplify speaker hookup and reduce installation time compared with spring clips, and the 230 V AC operation at 50 Hz matches standard mains supplies in many regions. The compact footprint and rack-compatible width facilitate integration into stage racks and flight cases without occupying excessive space.

How to use

Place the amplifier into a suitable rack or stable surface that provides adequate ventilation. Connect the amplifier to the mains supply rated at 230 V AC, 50 Hz using a properly rated power cable. Use the clamp terminals to attach speaker cables, ensuring correct polarity and secure connections. Adjust input gain and any front-panel settings according to the signal chain and maintain levels to avoid clipping. Allow the amplifier to cool during extended operation and follow standard soundcheck procedures before live use.

Recommendations

Use the amplifier with compatible passive speaker systems rated to handle the amplifier's output. Ensure proper ventilation around the unit and avoid operating at maximum load for prolonged periods to extend component life. Regularly check speaker cable connections and maintain grounding and mains safety according to local electrical regulations.
