Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| No Sound Output | Power not connected, input gain too low, audio source issue, faulty cable. | Check power connection and switch. Increase input gain. Verify audio source is active. Test with different cables. |
| Distorted Sound | Input gain too high (clipping), faulty cable, speaker overload. | Reduce input gain until clipping indicator is off. Replace faulty cables. Reduce overall volume. |
| No Wi-Fi Connection | Wi-Fi disabled on speaker/device, out of range, interference. | Ensure Wi-Fi is enabled on both speaker and mobile device. Move closer to the speaker. Check for other wireless devices causing interference. |
| Overheating | Obstructed ventilation, prolonged high-volume use in hot environment. | Ensure all ventilation openings are clear. Reduce volume or operate in a cooler environment. |
