Q: Why the amplifier distortion when raising volume ?

A: Under normal circumstances, distortion is caused by the mismatch between the power of the amplifier and the speaker. Therefore, it can be reasonably matched according to the ratio of 1.2-1.5 to 1 between the power amplifier and the speaker

Q: How to match the amplifier and speakers reasonably?

A: The best match is 1.2-1.5:1 (that is, the speaker power is 50W, then the power amplifier power is 60W-75W)

Q: The power amplifier is connected correctly, why is there noise such as electric current?

A: please check whether there is current sound when no load, and whether there is no current sound when no load, please replace the audio input wire and input device. If there is current noise at no load, you can replace the power supply to test again

At the same time, confirm that the surrounding current signals will not cause interference to the equipment
