Product Description

FACTORY

Product Description

The LC series are all produced using SMT production technology, using H-class and AB circuit technology, with high-efficiency power conversion and sophisticated circuit layout, using ultra-high power imported iron core ring transformer design, using 10000UF ultra-large capacity capacitor design, and low frequency.

The power amplifier adopts an optimized radiator structure and a high-quality cooling fan, which reliably guarantees long-term high-power operation; the fan automatically accelerates with internal temperature changes. When the connected load impedance 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, which can improve the sound quality and effectively protect the machine, greatly improving reliability; the power amplifier has a high conversion rate, beautiful tone, and low distortion.

The entire series adopts a 2U chassis structure design. With an LCD screen to display temperature, volume, working mode, etc. The potentiometers of this series of products use imported fully sealed potentiometers (moisture-proof, waterproof, and dust-proof, which is 20 times the service life of traditional potentiometers)
