5. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| No sound output | Incorrect volume settings, incorrect output selection in software, loose cables. | Check the Output Volume knob. Ensure the interface is selected as the output device in your computer's sound settings and recording software. Verify all cables are securely connected. |
| Input signal clipping (red light) | Input gain/level is too high. | Reduce the Gain or Level knob for the respective input until the red Clip indicator no longer illuminates. |
| Microphone not working (condenser mic) | 48V phantom power not enabled. | Press the +48V button to enable phantom power for condenser microphones. |
| No sound from instrument input | Instrument level too low, incorrect cable. | Increase the Level knob for the instrument input. Ensure you are using a proper 1/4" TS or TRS instrument cable. |
| Interface not recognized by computer | USB cable issue, driver issue (rare for class-compliant devices), faulty USB port. | Try a different USB port or cable. Restart your computer. While typically plug-and-play, ensure your operating system is up to date. |
