Hi, recently been trying to do some podcasting but while trying to get my equipment running I've been having some problems. I have a xp-202 sound preamp and a behringer c-3 condensor microphone. Everything has been running fine through the preamp, but whenever I try and plug in the mic I get nothing. The light that should indicate the power is on will not even start. I'm really at a loss, I've gone through the instructions in the manual step by step but have just had no luck. Any suggestions?
