Common problem:
1. When the volume is turned up, the sound will be stuck, intermittently, and it can be played normally when 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 540W. When choosing, it is recommended to choose a voltage of 32V and a current of about 17A.
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, the output is 50W. Connect a 5W speaker, the loudspeaker will show the phenomenon of freezing, and it may burn the speaker
2. The problem of Bluetooth connection failure.
Answer: The Bluetooth of the mobile phone is turned on, but the Bluetooth of the power amplifier board cannot be found. It is not possible to change the mobile phone to test.
If there is a problem with the module, you can contact customer service.
3. The mobile phone can be connected but the laptop or desktop computer cannot be connected.
Answer: If you can connect to the machine and play music, it is said that there is no problem with the Bluetooth power amplifier board. It may be that there is a problem with the computer's Bluetooth driver, the version is too old or there are files missing. It is recommended to uninstall and then install the latest version of the driver.
