FAQ:
1. About Bluetooth connection distance.
Answer: After testing, the distance between different mobile phones is different. The Bluetooth connection distance for OPPOR9m we tested is only 2-3 meters; while the Bluetooth connection distance for Honor and Apple mobile phones can reach more than 20 meters.
2. When it turns up, the sound will freeze, intermittently. After it turns down, it can play normally.
Answer: Reason 1: The power of power supply is too small. The total output power of this power amplifier board is 300W. When choosing a power supply, it is recommended to select over 21V and over 15A. Reason 2: If there is no problem with power supply, it may be that the power of the speaker is too small. For example, when the output is 100W, but a 50W speaker is connected, it will freeze when it turns up, and the speaker may be burned out.
3. There is too much noise when playing music, or there is noise level when not playing music.
Answer: The function of the power amplifier board is to amplify signals. The main source of noise is that the radio clutter in the environment is amplified by the power amplifier board, so as long as the power amplifier board is running, there will be noise. When choosing an audio cable, try to use the one with shielding function. It is also possible that the sound source is noisy. Normal mobile phones and MP3 have no noise. Most of them are on some old front-end boards, which are not compatible with our company's power amplifier boards. Audio isolators or coupling capacitors can be added to remove them.
4. Is it better to share a power supply or separate power supply?
Answer: Normally share a power supply. If sharing a power supply is noisy, it needs to be powered separately.
5. Bluetooth cannot be connected.
Answer: Bluetooth indicator light flashes regularly when it is working. If the Bluetooth indicator is always on or off, there may be a problem with the Bluetooth module. Please contact customer service in time.
6. Mobile phone can connect to it, but a laptop or desktop computer cannot connect to it.
Answer: If your mobile phone can connect and play music, it means 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 some files are missing. It is recommended to uninstall first and then install the latest version of the driver.
