6. Troubleshooting

If you encounter issues with your XY-AP100L amplifier board, refer to the following common problems and solutions:

• No Power:
  • Check if the DC power supply is correctly connected and providing the specified voltage (12V-24V).
  • Ensure the power adapter is functional.
• No Sound Output:
  • Verify speaker connections are secure and correct polarity is observed.
  • Check the volume level on both the amplifier board and the audio source.
  • Ensure the correct input mode (Bluetooth, AUX, USB) is selected and the audio source is playing.
  • Test with a different audio source or speakers to isolate the problem.
• Bluetooth Disconnection/Pairing Issues:
  • Ensure no other devices are actively connected to the amplifier board via Bluetooth.
  • Move your Bluetooth device closer to the amplifier board.
  • Try forgetting the device on your phone/computer and re-pairing.
• Distorted Sound:
  • Reduce the volume on both the amplifier and the audio source.
  • Ensure the power supply is adequate for the desired output level. A weak power supply can cause distortion at higher volumes.
  • Check speaker impedance compatibility.
