★FAQ★
1. When the volume is turned up, the sound is stuck, intermittently, and it can be played normally after the volume is turned down.
Answer: One reason: due to the low power of the power supply, the total output power of this power amplifier board is 60W. The recommended voltage for power supply selection is DC12V and the current is about 5A.
Reason two: If the power supply is ok, it may be that the power of the speaker is too small. For example, if the output is 20W, but a 3W speaker is connected, and the volume is turned on, there will be a freeze phenomenon, and the speaker may be burned out.
2. There is too much noise when playing music, or there is a bottom noise when no music is played.
Answer: The function of the power amplifier board is to amplify the signal. The main source of noise is that the radio clutter in the environment is amplified by the power amplifier board, so as long as it is the power amplifier board, there will be noise. It is recommended that the audio cable should be shielded as much as possible. It is also possible that the sound source is noisy. Normal mobile phones and MP3 will not have it. Most of them are on some old front-end boards and are not compatible with our company's power amplifier boards. You can add audio isolators or coupling capacitors to test. Cannot be rem
