Low output and distortion on mic pre, microbook II, resolved

Post by nick danger »

My Microbook II now has extremely low output on computer generated sources. Aux 1-2 and Mix 1 in cue mix show very little signal even when maxed out, but no noticeable distortion. The mic pre has plenty of volume, but intermittently generates white noise and/or severe distortion, which resetting to factory default seems to cure, but then it returns.

I don't think it's a problem with the USB bus from computer, but I don't have any way to test it.

Any suggestions?

thanks in advance
