The OMNITRONIC XPA-1000 MK2 is a professional 2-channel power amplifier delivering 2 x 500 W RMS at 4 ohms, engineered for demanding live sound and fixed installation applications. Its robust Class AB design and comprehensive protection circuitry ensure reliable performance even under continuous high-load operation.

Advantages

With a high damping factor of >350 and a signal-to-noise ratio exceeding 90 dB, this amplifier provides tight bass control and a clean, transparent sound. The bridge mode offers 1000 W RMS at 8 ohms for driving high-power subwoofers or full-range cabinets. Dual variable-speed fans keep the unit cool while maintaining low noise, and the ground lift switch helps eliminate hum in complex setups.
