A common question we get is "how do I get the configuration so that I can switch easily from headset to speakers by using the switch?"
There is no configuration to switch between the headset and speaker settings. The headset uses its own input port on the control box, when you connect a headset to the control box, it will automatically pass sound to your headset.
The source 1 and 2 on the control box control the audio input sources connected at the back and front of the control box respectively.
The audio source 1 at the back uses the 3.5mm to RCA and the front uses the 3.5mm to 3.5mm.
