6. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| No sound output | Incorrect routing, muted channels/main, low gain, faulty cables. | Check routing in X AIR app, unmute channels/main, increase gain, test/replace cables. |
| Wi-Fi connection issues | Incorrect network mode, weak signal, interference, incorrect password. | Verify network mode (Client/Access Point), move closer to mixer/router, check for interference, re-enter password. Consider using an external router for stability. |
| USB recording not working | Missing/incorrect drivers, incorrect DAW settings, USB cable issue. | Install/reinstall latest drivers, ensure XR18 is selected as audio device in DAW, try a different USB cable/port. |
| Distorted audio | Input gain too high (clipping), faulty cable, damaged speaker/microphone. | Reduce input gain, check cables, test with different speakers/microphones. |
