6. Nota importante sulla compatibilità

This device is designed to work exclusively with 3-pole 3.5mm audio cables (TRS). It is not compatible with 4-pole 3.5mm cables (TRRS) which typically include a microphone channel. Using 4-pole cables may result in improper functionality or no audio output.

7. Risoluzione Dei Problemi

• Nessun suono:
  • Ensure all 3.5mm cables are securely connected.
  • Verify that the correct input/output is selected using the 1/2 switch.
  • Check if the mute button is engaged.
  • Confirm that the volume knob is turned up.
  • Ensure you are using 3-pole 3.5mm audio cables.
• Suono distorto:
  • Controllare che i collegamenti dei cavi non siano allentati o danneggiati.
  • Reduce the volume from the source device or the selector.
  • Test with different audio cables to rule out cable issues.
• Only one output device works in 1-IN-2-OUT mode: This is normal operation. The selector is designed to switch between outputs, not to split the signal simultaneously to both.

8. Cura e manutenzione

To ensure the longevity and optimal performance of your audio selector:

• Conservare il dispositivo in un ambiente asciutto, lontano da umidità e temperature estreme.
• Pulire l'esterno con un panno morbido e asciutto. Evitare l'uso di prodotti chimici aggressivi o detergenti abrasivi.
