Four-Channel Power Amplifier CSD200

CSD series of amplifiers are Pure post-stage audio power amplifiers with high S/N ratio, low power consumption, high efficiency as well as multi-protection such as protection from burning, load short, overvoltage, direct current, distortion, etc. The product adopts the electronic components of global brand as the main material like capacitance, amplifier tube, silent roll-ball fan, etc. Adopting the high precision SMT tech and high density aluminum alloy for heat dissipation, the amplifier uses the wide voltage and high power power supply and PFC for voltage stabilization so that it can work normally in low voltage because of the enough energy.
