Right output louder than left??

Why is my right output louder than my left on my 4000? When I track into my DAW the right side of all my tracks are louder for some reason...

This may sound dumb, but check the gains on the R/L track....I have done this A LOT. Sometimes when I'm hooking up cables I will knock the gain knob on the back of my monitors down or up, same goes with my mixer gain for each channel. If not, plug in some headphones and see if it sounds like that....if so, it could be the samples and drums that you use are panned to one side from the original mix. If the headphone jack is fine, you could have a high Ohm (electrical resistance) in a channel and that might require an electronics specialist like Armen to take a look at it. Good luck.

Also, roll the cables and see if the problem follows.
