8. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| No sound output | Volume levels too low; incorrect connections; muted output. | Check all volume knobs and faders. Ensure cables are securely connected. Verify the Mute On/Off button is not active. Check device audio settings on your computer/phone. |
| Microphone not working | Incorrect microphone input; 48V phantom power off (for XLR); microphone volume too low. | Ensure the microphone is connected to the correct input. If using an XLR condenser mic, activate 48V On/Off. Adjust microphone volume faders. Test with another microphone if possible. |
| Bluetooth connection issues | Mixer not in pairing mode; device too far; interference. | Ensure Bluetooth is enabled on both devices. Move devices closer. Restart both the mixer and the Bluetooth device. |
| Device not charging or powering on | Faulty cable; insufficient power source; battery depleted. | Ensure the charging cable is properly connected to the Type-C Power port. Use a reliable 5V/1A power source. Allow the device to charge for a period before attempting to power on. Try a different USB-C cable. |
| Sound quality is poor or distorted | Input levels too high; incorrect EQ settings; cable issues. | Reduce input volume levels to prevent clipping. Adjust microphone EQ faders. Ensure all cables are in good condition and properly connected. |
