I bought a radio shack wireless mic and plugged it into audio 1, left the switch to mic and did not have any luck recording from it. I have read the manual several times, but can't figure out what I am doing wrong....besides buying a cheap mic, that is.
Have you checked that you are getting signal to the base unit / reciever of the lav / handheld? Usually there will be some indicator (led strip) showing signal strength. If you'r getting signal there, try using a different XLR cable.
