PK-650

The PK series power amplifiers are the best choice for high fidelity professional sound reinforcement systems. Currently, they represent high-end power amplifiers in the market, with superior linear power supply systems, abundant power reserves, multiple optimized circuit designs, and various high-quality raw materials carefully selected globally, ensuring the high fidelity and low distortion sound quality reproduction of power amplifiers. It has perfect power amplifier and speaker protection circuit, including suppression of switch shock, Infrasound, ultrasonic, and radio frequency; Load short circuit, open circuit, overload, overheating, and clipping distortion limit protection; And load protection for DC faults, providing strong guarantees for the long-term and dynamic safe operation of the entire sound reinforcement system; The unique improved design of the heat dissipation system effectively improves the heat dissipation performance by 30%. The cooling airflow filtered by the dust cover only passes through the heat dissipation fins that need to be dissipated. While strengthening heat dissipation, it avoids machine failures caused by dust and smoke pollution of the circuit board, keeping the power amplifier in a long-term working state at room temperature. The chassis is made of integrated steel plates stamped by precision CNC lathes, with a stable structure that can withstand great instantaneous pressure without deformation. The aluminum alloy panel is designed with a highly modern ACS brand culture.
