I struggled with that issue a big part of the day. I put the mic auto set-up and ran that... not that I figured my issue would be fixed by that, but it's all I hadn't tried. I thought you guys were going to tell me it's normal. I was worried. After the mic calibration thing, guess what! Who knew it was mandatory to use the mic calibration!? I have a feeling I'll come back here to the forum... it's a heck of a preamp that I still no nearly nothing about. Talk at you later.
