Question:
Zhongshan, Guangdong produced a “Japan” before and after the class amplifiers, can be a normal public address, work properly. but the side-channel heat sink than the on the other side is much higher, and in the absence of audio input, a separate open-amplifiers when the side of the heat sink will be burning less than one minute. I ask why? Are there short-circuit phenomenon?

Answer:
amplifiers and the load necessary to connect (that is, and speakers connected to) and Amplifier output power and load power necessary to match the impedance matching. Otherwise, it will heat amplifiers. Please check the match situation, discharge matching problem, the amplifiers can be considered faulty.

Answer:
not now access the audio input amplifier also has a separate open-side heating phenomenon can be sure the side channel of the amplifier is faulty. May be the output IC, the output capacitance of circuit failure.
