I am utterly baffled. I have been trying to get some lavalier microphones to work with a standard mixer than accepts an XLR jack. I have tried 2 different sets of mikes, and 2 different mixers, and I can't seem to get any sound out at all. The set up: 2 x lavalier microphones (a 'set') with mini XLR plug -> mini XLR plug to XLR -> plugged into mixer Edirol M-100FX no sound I have tried switching phantom on and off. It doesnt seem to make any difference. I have played with all the faders, trims, mute etc. I have checked one set of mikes for loose soldering. In my good few years of AV work, I must be either completely mad, or coincidently have bought 2 dud sets of mikes in a row!
