How do you know when you might have a problem with your r-09's input? I've been getting alot of audio break up on my recordings lately. I've replaced the cable and that didn't fix the problem. I've tried another set of mics & pre-amp and it seems to be on the same channel (left). I remember awhile back there was a discussion about the input jack being alittle delicate.
Any thoughts or suggests? I have logged alot of miles on this unit.
