so recently, I'd noticed some one channel static. thought it was the old audio magic interconnects, so bought some leegeddys. ok for awhile, problem crops up again. hook the gear up at home, and discover what I think is a bad active cable in one mic, because I got static when jiggling the cable where it exits the cap.
well, a couple of years ago, I got some wire ties at home depot, to avoid tangling. When I unclipped the cables so I could send the bad one into DPA....voila, the static is gone. What I realized is that over the years, due to environmental factors or whatever, the actives were getting severely pinched. you could see deep marks on the actives. seem fine now. so don't do like me....use something other than wire ties.
