So I'm doing a sound job now. I was using an EV RE 27/nd on the kick drum and it was doing great. Suddenly it cut out in the middle of the set. It wasn't dropped, kicked, or impacted in any way. It was secure on it's stand. I switched thru 3 cables and got nothing. Tried another channel, nothing. Switched out with a Beta 52a and everything's working again. I brought the Re27 back to the board with me. I muted a mic I was using on an open channel for talkback...using the meters I saw the tb mic was working. I switched the tb mic with the re27...nothing. I need to take a look at the mic more carefully at home, but can anyone give me some potential problems to look for? The mic has never given me trouble. Like I said it was secure on it's stand. I have no idea why it suddenly cut out. Any help would be appreciated.
