Working a show the other night, and lost signal on this input channel. Obvious troubleshooting with changeout on mic cable and microphone did not work. Proceeded to spinning the input gain knob and surprisingly the signal came back strong at the 12:00 position.
I recall reading something in the past on the possibility of a board replacement in the mix rack. Curious if anyone else has gone through this type of issue, and how it was resolved.
Had the same problem with my C1 input, got it to the repair shop and the removed the hole C1-C8 card and I got a new one… it seams to be a “normal” problem.
