Right side louder than left side..

Hey everyone I am new to the forum. :)

I have a problem where the left speak is a lot quieter than the right speaker. On the actual mixer itself (Xone32) the difference is visible on the left and right dials. I have tried both decks (1210's) with the same result so it seems to me like a mixer problem. I am just wondering if there are any other reasons that this could be happening? Also if it is the mixer what could be the actual problem with it and could I fix it myself?

Any help on this would be great!

Thanks

Sorry for the insulting question but have you looked @ the balance knobs?

Is it uneven when you listen through the headphones? How does it sound when you change headphones between Cue and Master?

When you say you have tried both decks, do you mean it's happening on both channels? or you have tried two decks on the same channel with the same result?

Are you using a DVS? What happens when you play normal vinyl?
