Troubleshooting

No sound from speakers

Ensure the amplifier is powered on. Check all speaker connections to the amplifier and verify speaker polarity. Confirm the Bluetooth device is successfully paired and playing audio. Increase the volume on both the Bluetooth device and the amplifier.

Bluetooth device won't connect

Make sure the amplifier's Bluetooth is active (indicator light on). Turn off Bluetooth on your device and then turn it back on. If issues persist, try restarting both the amplifier and your audio source device.

Distorted or crackling sound

Check speaker cable connections for looseness or damage. Ensure the speakers are within the 4-8 Ohm impedance range supported by the amplifier. Reduce the volume to avoid clipping. Verify the audio source is not sending a distorted signal.

Amplifier not powering on

Verify the 12V PSU is securely connected to the amplifier and the power outlet. Check if the power outlet is functional. If the issue continues, the PSU or amplifier may require service.
