Thank you for your reply.
I don’t believe that answers my question. I can see the “Invert Polarity” button on all my channels.
But my overheads are a pair, linked together using the “Stereo Link” button in the Inputs Config screen.
The polarity option would seem to apply to both of these, which is helpful, but I want to know if I can flip just one of them, so they sound best on the snare drum, etc.
Neither page 80 nor the Processing detail screen for a linked pair of inputs seems to have that option. I’m hoping it’s not “Unlink, flip one, relink” because that would be both a glitch in the workflow, and not possible to see once linked, I think.
