KV series features: All products are produced using SMT production technology, adopting H-class circuit technology, with high efficiency power conversion and excellent circuit layout. It adopts a high-power imported iron core toroidal transformer design, a 10000UF ultra large capacity capacitor design, and a low-frequency robust. The amplifier adopts an optimized heat sink structure and high-quality heat dissipation fan, which ensures reliable long-term high-power operation; The fan accelerates automatically with random temperature changes. When the impedance of the connected load is too low or the temperature is too high, the machine will adjust the power supply to reduce the internal resistance of the power supply, improve sound quality, and effectively protect the machine, greatly improving reliability; The amplifier has a high conversion rate, beautiful sound quality, and low distortion. The entire series adopts a 2U chassis structure design.
