I have been happy with the performance of this wireless mic using the supplied lavalier. I am trying to make my boom mic wireless as well. I purchase an XLR to locking plug connector to be able to go out of my boom mic to the transmitter. Unfortunately the level coming into my camera is way too low and I can't seem to bring it up so I can hear it. Test recordings yield very low level performance. Do I need an amp of some kind? What am I missing?
