I'm using 2 ADK small condenser mics for overheads but I have a problem. I'm running all of my other mics (snare, kick, toms) into a Mackie mixer, but when I run the overheads through there there isn't enough gain (I guess) in the pre's to push them enough. I tested one through the Mackie with the input nearly cranked and ran the other one through my UA610 pre set at about 2 and a half, and there was no comparison, the UA blew it away. My question is, since the UA pre only has one input, I obviously need to find a 2 channel pre that can push those enough. Suggestions (on the cheap)? Thanks-
