Talkback Configuration
You can use the iD22's microphone input as a talkback microphone. Allowing you to speak to your artists with kind (or not so kind) words of encouragement. It may be best to use an external pre-amp when using this configuration as you will only have one mic-pre remaining to record through.
Software Setup
The Talkback is sent out using Cue A, this means you can also send foldback to the artist by simply lifting the faders of Cue A on the channels you would like your artist to hear.
