I have my mic hooked up through my mixer, and my mixer is connected to my computer. I have tried diff volumes, and right now I have gotten the best sound from turning the main vol almost all the way down and turning the mic volume all the way up. I have gotten a pretty good quality from that and if you have any better suggestions it would be greatly appreciated. 2nd, I have a problem with adjusting the bass to a point where its not all the way down, but it does not cover the vocals. Like in many rap songs, the bass can almost knock off your trunk but the vocals are still at a level where they can be heard.
