audio amplifier

The machine is accordance with the classic H type circuit  design, high efficiency power output, improved overload, short-circuit, limiting protection. CPU intelligence third-level hot protection, cut down input signal or cut off overload according to radiator and transformer's temperature situation When protection the built-in bee funerary objects can give the alarm sound , simultaneously the front panel response function's instruction lighting to be bright.
