Important Notes

1. We don\'t recommend to use the 3.5mm port and RCA port on the adapter simultaneously, because one of the output device’s volume may decrease.

2. To ensure proper hardware detection, plug the external headset into the adapter first, then connect the adapter to PC.

3. Mono Microphone requires TRS connector (not TS or TRRS).
