If you encounter issues with your TOPPING E2X2, refer to the following common troubleshooting steps:

Pas d'alimentation : Ensure the USB-C cable is securely connected to both the E2X2 and your computer/power source. Try a different USB port or cable.
No Sound (Input):
- Check if the microphone/instrument is properly connected to the correct input.
- Verify that the GAIN knob for the respective channel is turned up.
- Si vous utilisez un microphone à condensateur, assurez-vous que l'alimentation fantôme 48V est activée.
- Check your computer's sound settings to ensure the E2X2 is selected as the input device.
No Sound (Output):
- Ensure headphones or speakers are correctly connected to the output jacks.
- Adjust the MONITOR knob to increase output volume.
- Check your computer's sound settings to ensure the E2X2 is selected as the output device.
- If using the INPUT/PLAYBACK button, ensure it is set to PLAYBACK for DAW audio.
Bruit/bourdonnement excessif :
- Assurez-vous que tous les câbles sont correctement blindés et solidement connectés.
- Check for ground loops. Try connecting the computer and E2X2 to the same power outlet.
- Reduce input gain if the signal is too hot (clipping).
Software Not Recognizing E2X2:
- Restart your computer and the E2X2.
- Reinstall the latest drivers and control software from the TOPPING website.
