Yeah, I'm using a pre to go through the front and rear, but honestly, it sounds "right" in the front. For instance, if I run the kick drum through one of the rear inputs, there is absolutely no low end at all. I'm trying to compare it to something but all I can think of is "thin", not at all how it should sound in a mix. As far as double amping the front, I mainly do that so I can control the eq on the board going in, I don't have to mess with the stupid firewire control thing. And, again, it sounds good. Can you explain more about the unbalanced vs. balanced, line input vs mic input ? Thanks
