Common problem:
1. The question about the length of the Bluetooth connection distance.
A: After testing, the distance between different mobile phones is different. The OPPOR Bluetooth connection distance we tested is only 2-3 meters; and the Bluetooth connection distance between glory and Apple mobile phone can reach more than 20 meters.
2, the volume is turned up, the sound appears to be stuck, intermittent, and the volume can be played normally after the volume is turned down.
A: One of the reasons: due to the power supply is too small, the total output power of this Bluetooth power amplifier board is 300W. When the power is selected, the recommended voltage is above 21V and the current is above 15A.
The second reason: 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 100W, but a 50W speaker is connected, the volume will be louder, and the phenomenon will be stuck, and the speaker may be burned out.

3. The noise is too loud when playing music, or there is no noise when playing music.
Answer: The function signal of the power amplifier board is amplified. The main source of the noise is that the radio clutter in the environment is amplified by the power amplifier board, so there will be noise as long as it is the power amplifier board. Therefore, the audio cable should be shielded as much as possible. It is also possible that there is noise in the sound source. Normal mobile phones and MP3s will not be available. Most of them are on some old preamp boards. They are not compatible with our company's power amplifier boards. It can increase the audio isolator or the coupling capacitor.
 
4, the problem of power supply, share a power supply or separate power supply?
A: You can share a power supply normally. If you share a power supply, you need to separate the power supply.
 
5, Bluetooth connection is not a problem.
A: The Bluetooth indicator flashes regularly when it works normally. If it is bright or not, there may be a problem with the Bluetooth module. Please contact us in time.

6, the phone can be connected but the notebook computer or desktop can not be connected.
A: If the phone can connect and play music, there is no problem with the Bluetooth power amplifier board. It may be that there is a problem with the Bluetooth Bluetooth driver. The version is too old or there is a file loss. It is recommended to uninstall and then install the latest driver.
