global power supply; switch power supply with PFC; Class D digital amplifier; Low noise; flat frequency response curve;

FEATURES

     PAL QR600 digital amplifier adopts technology of PFC switch power supply and Class D digital power amplifying circuitry. This digital power amplifier features light weight, brilliant sound, high efficiency, reliable performance, and complete protection function (short-cut protection, over-current protection, over temperature protection, over-or-less-voltage protection, temperature limiting), working at the power supply voltage VAC90-264, 50/60Hz, better electromagnetism compatibility.

 

Features

·Universal power supply: 90V -- 264V, switching mode power supply with PFC

·nice sound with flat frequency response curve from 20Hz to 20KHz

·very high switching frequency: 400K Hz

·quite low noise, THD+N: 0.01%

·usage and testing method are same with analogue amplifier

Other Features
