6. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| No power | Power adapter not connected or faulty. | Check power connections. Ensure the power adapter is functional. Consider using a certified replacement if suspected faulty. |
| No sound output | Incorrect input selected; volume too low; speakers not connected; muted. | Verify input source. Increase volume. Check speaker connections. Ensure unit is not muted. |
| Sound skipping or intermittent audio (especially Bluetooth) | Weak Bluetooth signal; interference; source device issue. | Ensure Bluetooth antenna is securely attached. Move source device closer to the amplifier. Reduce interference from other wireless devices. Try a different audio source. |
| Clicking or popping noise when switching inputs/sampling rates | Normal operation for some digital audio processing. | This may be inherent to the device's design during input or sampling rate changes. If excessive, contact support. |
| Faint abnormal noise during silence | Ground loop; electrical interference; internal component noise. | Ensure all connections are secure. Try plugging the amplifier into a different power outlet. Disconnect all inputs to see if the noise persists. |
| Remote control unresponsive or erratic | Low or dead batteries; obstructed IR sensor; remote malfunction. | Replace AAA batteries in the remote. Ensure no obstacles between remote and amplifier's IR sensor. Point remote directly at the amplifier. |
| Sound disappears after a while with USB connection, cycling SELECT restores it | USB driver issue; compatibility issue; temporary software glitch. | Ensure your computer's USB drivers are up to date. Try a different USB port or cable. Cycling the SELECT input can temporarily resolve this. |
