Trying to boost the volume of my tracks as when they come through the mixer they still have to be turned up to max on the mixer to match volumes of the decks.which are only at half volume on the slider.

Also to get my tracks to equal bass I have to give it nearly a quarter extra bass on the mixer to give me the sound I'm after. When I try doing this in the track everything overloads and I have to reduce the overall volume.

What am I missing. Compression still sounds really muddy to me and interferes with the clarity of my sounds and doesn't seem to effect the volume by much at all so I'm convinced it's something else. What could it be?
