product introduction

PDSeries power amplifier Professional power amplifier series adopts stableTClass I circuit design, the product focuses on stability under long-term continuous full power use conditions. The circuit board is designed through a computer simulation system, and the main components are processed usingSMTTechnical manufacturing;PDThe series power amplifiers adopt an optimized radiator structure and high-quality cooling fans, which ensure long-term high-power operation; interactive control function allows the fan to automatically accelerate due to random temperature changes. When the impedance of the connected load is too low or When the temperature is too high, the machine will adjust the power supply to reduce the internal resistance of the power supply, which can improve sound quality and effectively protect the machine, greatly improving the reliability;PDThe series of power amplifiers have high conversion rate, beautiful tone, and low distortion. The entire series adopts2UCabinet structure design.
