While sidetone is not adjustable on the RIG system, there are ways to manage it:
If the voice feedback seems too loud, position the mic farther from your mouth or speak more softly. The highly sensitive noise cancelling mic on RIG will pick up your voice clearly even if it's a bit further from your mouth.
You can also use the audio settings in your control panel to turn down the sensitivity of the microphone.
If you’re not chatting or using the microphone, pressing mute on the RIG mixer will eliminate any feedback from the mic.
