$269.00

Stereo amp with integrated Adaptive Voltage Switching Power Supply for explosive power and ultra-low distortion.
Peak Power: 300W@4ohm, 180W@8ohm.
RMS power: 260W@4ohm, 150W@8ohm.
Heatsink, mounting bracket, RCA inputs, and cables included.

Description

The NPX-280ASP has advanced protection circuitry that safeguards it from fault conditions such as short circuits, overload, over temperature, and under-voltage.

The amplifier’s output signal feeds back into the Adaptive Voltage Switching Power Supply’s servo power stage, causing a change in the output voltages supplying the power stage of the amplifier. This design resulted in more details at a low music level and explosive power at a high volume.
