7. Fehlerbehebung

If you encounter issues with your LiNKFOR Audio Switcher, please refer to the following common problems and solutions:

• Keine Tonausgabe:
  • Ensure all 3.5mm audio cables are securely connected to their respective ports on both the switcher and your audio devices.
  • Überprüfen Sie die Lautstärkeregler on the switcher and ensure it is not set to minimum.
  • Überprüfen Sie, ob die Stummschalttaste is not active (press it to unmute).
  • Confirm that the correct input/output is selected using the 1/2-Schalter Taste.
  • Ensure that the audio source device is playing sound and its volume is turned up.

  • Prüfen Sie alle Kabelverbindungen auf festen Sitz.
  • Try using different 3.5mm audio cables to rule out faulty cables.
  • Ensure the volume levels on both the switcher and your connected devices are not set too high, which can cause distortion.
