8. Dépannage
| Problème | Cause possible | Solution |
|---|---|---|
| Pas de courant | Incorrect or insufficient USB power supply. | Ensure the USB power adapter is properly connected to a wall outlet. If using a computer USB, try a different port or a dedicated USB power adapter (recommended). Verify the power source provides at least 5V and 1.5A. |
| Pas de son ou volume faible | Incorrect connections, low gain/volume settings, phantom power off for condenser mics. | Check all input and output cable connections. Increase GAIN for input channels, MAIN volume, and PHONES volume. Ensure +48V phantom power is engaged for condenser microphones. |
| Bourdonnement ou bruit statique | Ground loop, insufficient power, poor quality cables, interference. | Use the provided USB power adapter plugged into a wall outlet instead of a computer USB port. Ensure all cables are good quality and properly shielded. Try isolating the mixer from other electronic devices. |
| USB recording/playback issues (disconnects, not recognized) | Faulty USB cable, computer port issues, driver conflicts. | Try a different USB cable and a different USB port on your computer. Restart your computer. Ensure your operating system has the latest audio drivers. |
| Cannot record multiple microphones to separate tracks | The mixer outputs a stereo mix, not individual tracks. | This mixer is designed to output a combined stereo mix to your computer. It does not support multi-track recording of individual inputs. For multi-track recording, a dedicated multi-channel audio interface is required. |
