The concept of audio mix-minus is to provide remote contributors with a return feed containing the full mix of the program audio except for this remote contributor’s audio – in order to avoid audio loopbacks. If mix-minus is not configured, the job will be done by the built-in echo cancellation algorithm, which doesn't always work perfectly.
To enable automated mix-minus for Web Guests you have to pick one source in the Publisher application that you are going to send as the return feed to guests, right-click on this studio feed, open the Settings window and enable the switch “Web Guest Mix-Minus enabled”, restart the feed and you are ready to go. All the guests connected to Web Guest URL will have their own personal mix-minus and will hear everyone else connected to the same Guest URL.
All mix-minus creation is handled inside the VT Publisher application automatically for up to 8 guests.
The studio feed should contain only audio originating from the studio, you have to exclude all the guests from that mix. The Video Transport application will add all necessary guests automatically while creating a personal mix for each guest.
