Our compressor might not be the best option because it's a feedback compressor. By inserting a completely different signal into the side-chain the unit will respond pretty differently than intended. Usually people are just EQ'ing the side-chain. So the feed-back signal is just a variation on the input signal, not a completely different one. 


Also you'll need to use a Mic Preamp,because the signal coming from the microphone is typically much lower than line-level.
