8. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| No power | Power cord not connected; Power switch off; Power outlet faulty. | Ensure power cord is securely connected. Turn on the power switch. Test the power outlet with another device. |
| No sound output | Incorrect input source selected; Volume too low; Speakers not connected correctly; Speaker type incompatibility. | Select the correct input source. Increase master volume. Check speaker connections and polarity. Verify speakers are fixed resistance type. |
| Microphone hissing sound | Magnetic interference from condenser microphones. | Use dynamic microphones instead of condenser microphones. Alternatively, place a magnetic block near the microphone ports to reduce interference. |
| Bluetooth not connecting | Amplifier not in Bluetooth mode; Device too far; Device already connected to another amplifier. | Ensure amplifier is in Bluetooth mode ("BLUE" on display). Move device closer to the amplifier. Disconnect from other Bluetooth devices. |
| USB/SD card not playing | Incorrect file format; Card/drive not inserted correctly; Amplifier not in USB/SD mode. | Ensure audio files are supported (FLAC, WAV, APE, MP3). Reinsert the USB drive/SD card. Switch amplifier to USB/SD mode. |
