FAQ

The sound can be played normally, but there will be a "crackling speaker" noise from time to time?

Because the quality of the power socket is poor, the phosphorus copper sheet used inside is of poor quality and poor elasticity.

The sound of the speaker is played normally, but one speaker is loud and the other speaker is quiet. If you push the volume potentiometer hard to the side with your hand, the volume of both channels will be the same?

This is an issue with the volume potentiometer. Because the left and right channels of the volume potentiometer are independent.

Overheating

If the amplifier is overheated, it may cause the amplifier performance to deteriorate or even be damaged. This may be due to poor thermal design of the amplifier, or the amplifier is overloaded.
