7. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| No sound output | Power off; incorrect connections; output level too low; amplifier off. | Check power, all cable connections (input/output), increase OUTPUT LEVEL, ensure amplifier is on. |
| Microphone not working | Mic level too low; faulty microphone/cable; mic not fully inserted. | Increase MIC LEVEL, test with another microphone/cable, ensure mic cable is fully inserted and making proper contact. |
| Distorted sound | Input/output levels too high (clipping). | Reduce MIC LEVEL or OUTPUT LEVEL until CLIP indicators/meter no longer show consistent clipping. |
| Voice Canceller ineffective | Original audio track not suitable for voice cancellation. | The effectiveness varies greatly with the source material. This is a characteristic of the technology. |
