Oooooh, THANKS! Hadn’t thought about using a Matrix.
Check me on this, please – the matrix setup is similar to setting up sends on an aux?
As in, hit the MIX button on the fader assigned to the matrix, and modify the LR fader [in my case] to taste.
I haven’t found much online info about the matrices. [although I understand them conceptually – just not specifically here].
The Peavey unit is about a decade old, so I think I’l try to pull it out of the path while I’m messing with the system. Leaving it in is Plan B. Plan 9 from Outer Space involves a trip to Dunkin, down the street….
Thanks so much for letting me borrow your brain. You just saved me from a whole lo of agony!
