Gold-plated XLR and 1/4" TRS Phonejacks input connectors.

Powerful, high current, low noise toroidal transformer.

Quiet, isolated cooling system.

Symmetrical, modularized design for easy transportation and quick service.

Front mounted, detent volume controls.

LED display for signal level (-10dB, -3dB, clip) and speaker protect for each channel.

Stereo/Parallel and Bridge Mode operation.

ProPower Audio HP Series feature a highly dynamic, ultra-low distortion pre-driver circuit. The discrete complementary-symmetrical push-pull cascade amplifier circuit of this type is only found on high end amplifier models.

Powerful MOSFET current-driver transistors are used to drive the output stages. Only one pair of MOSFET current-driver transistors is used in the design to drive the output power transistors in order to get the best current acceleration and to reduce distortion, which comes from too many orders of current amplifying. The design arrangement also minimizes the possibility of feedback.

Direct coupled NFB and DC servo easily handle subwoofers. A stable direct couple negative feedback with DC servo circuitry is applied for the best ultra-low frequency performance.
