Hi, I have a hanging mic and floor mic on seperate channels on a mackie 1402-vlz pro mixer. the mixer then goes to an amp, and then to my speakers. The problem is I can't get anything out of either mic. I have a few wireless mics on the board as well and they work fine. I have phantom power turned on, checked and replaced all the lines and connections, still nothing. Any thoughts on this would be appreciated, thanks.
