common problem
1. When the volume is turned up, the sound will be stuck, intermittently, and it can be played normally after the volume is turned down.
Answer: Reason 1: Due to the low power of the power supply, the total output power of this power amplifier board is 200W. When selecting the power supply, it is recommended to select the voltage at 24V and the current at about 8A.
Reason 2: If there is no problem with the power supply, it may be that the power of the speaker is too small. For example, if the output is 50W, but a 5W speaker is connected, the sound will be stuck when the volume is turned on, and the speaker may be burned out.
⒉. 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 to choose the audio cable with shielding function as much as possible. It may be 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, which are not compatible with our company's power amplifier boards. You can add audio isolators or coupling capacitors to test. Remove.
