Hi everybody. As you can see in my signature, my school is opening up with Music Man tomorrow and we had something weird happen last night. I have an ecclectic mixture of wireless microphones ranging from AT 1400's to our newest which came with our new building... telex FMR-500's. One of our telex mircophones came down with an issue last night that still has me baffled today. We were going through check. The girl assigned the mic (who is also the lead) was talking but we were getting no signal. She then started tapping on the little mic head (I think the FMR-500's use the EV ELM-22 mini microphone). I usually freak out when kids do that, but I noticed that when she tapped it, it would come over the pa and show signal on our board. When she talked... nothing. I took an alcohol wipe and cleaned the mic head to see if maybe there was some gunk keeping the weaker energy of her voice from creating enough signal versus the higher energy of her tapping. Nothing I did worked and by the end of the little microphone session I was screaming into the mic to no avail and yet the slightest tap would make a "thunk" sound in our system. Anybody else have this happen? If so what was the problem? Personally I am ordering a new element to be next day aired to me in hopes that I'll have the microphone for our show (even though I won't have it for our AM high school production). Thanks! Tenor.
