How to setup a mix minus workflow for a remote guest?
- First, add your live source(s) and remote guest input.
 
Set the audio output workflow from the Audio mixer.
- Enable the audio fader from your live source & the remote guest into P1.
 - Add a second audio output bus P2.
- Enable P2 output bus on the live source input fader only.
 
 
P2 will be used as mix-minus and sent to the remote guest.
Set the guest video & audio return
- Go to the guest management panel.
 - Assign the Program to the video return.
 - Select the audio track 2 (P2).
 - Save the changes.
 
That's it! When your remote guest will join the live event he'll be able to hear the full program mix minus his own voice audio.
