Currently Being ModeratedDec 11, 2012 4:25 PM (in response to M-Jay)Re: Grouping and parallel compression
This would require the use of a monitor send patched back into an input of the M20d. In this case you would create your group consisting of the 3-5 background vocals and send that group to Monitor Send D. ONLY that group should be assigned to Monitor Send D. Then connect a cable from Monitor Send D to an open mic/XLR input or a Line input. Make sure you have your Monitor Send level up - by the way this is another gain stage that allows control of your parallel input coming back. Now that group of background vocals is coming back in input 12 or 14 etc. And that signal can be compressed separately and in parallel to the individual background vocals that you have grouped together.
I hope this is helpful. I have not attempted this in live settings and it *may* be more suceptable to feedback.
