efficiency of the whole machine up to 89%, as well as the sound quality of class A power amplifier, and save power;
* Regulated switching power supply, to ensure that the output power of the amplifier is
constant under the environment of AC 190-260V, and it will not decrease due to the voltage drop;
* Using the original imported high-power fan, the high-speed dust removal function of the
boot fan, and the infinitely variable air-cooling control circuit; the intelligent power limit function can set the most
matching output power according to the impedance and power requirements of the speaker;
* Full-function protection: soft start at boot, overheating short circuit, DC output,
peak voltage limit, intelligent peak clipping protection, output zero current switch;
