KD-3

The KD series of analog professional amplifier circuits are manufactured using SMT technology and class AB&H circuit technology, with sophisticated circuit layout and high-efficiency power conversion. It features a super-power imported iron-core toroidal transformer and a super-capacity 10000UF capacitor design, delivering clear mid-to-high frequencies, rich low frequencies, and sufficient power reserve. High-quality cooling fans and optimized heatsink structures are employed, with fans automatically accelerating as the internal temperature changes, ensuring reliable operation during long-term high-power work. When the connected load impedance is too low or the temperature is too high, the device will adjust the power supply and reduce the power supply internal resistance, which can improve sound quality and effectively protect the device, greatly enhancing stability. The power amplifier boasts a High Slew Rate, beautiful timbre, and low distortion. It uses imported fully sealed potentiometer for moisture, water, and dust resistance. The entire series features a 2U chassis structure, which is compact and lightweight, with an LCD screen displaying temperature, volume level, working mode, etc.
