DESC: Precision Power again combines its rock-solid PWM regulation with the efficient power delivery of class D. From the 500 watt (Max Power) D500/1 to the potent D3000/1, these four mono block designs are based on extraordinarily robust power supplies with ultra-flexible front ends, all housed in a sleek new industrial design. Extruded top panels extend heat sink heat dissipation across the entire top surface of the amp, improving thermal run times & allowing smaller overall dimensions. Back-lit engraved-metal badging and an interactive illuminated PPI lightning logo that indicates amplifier status complete the advanced look.
