DDJ SZ 12 decibel diference between left and right channel

Hey guys,

I have a pioneer DDJ SZ and I recently found out that there is a 12DB difference between my right and left channel. The right channel is 12DB's higher than the left. I never noticed until I had a gig at a club who had a front of house guy running sound. He mentioned it to me. Prior to this gig I was just running my own sound through my jbl's. I can deal with 2 or 3 DB difference but 12!?! I called Pioneer and they said that they only cover issues during the first year. I called them THREE days after one year and they wouldn't help me. I even asked what they suggest I do and they had nothing to say. Awesome. So, I was wondering if anyone else has experienced this and if they have a solution I haven't tried.

I have checked the xlr connections, uninstalled and reinstalled software, checked for panning (there isn't a pan feature anyway but I checked). The controller is brand new and has been in the super nice pioneer case that I purchased with it since I have owned it. Sucks because I have only used pioneer (djm 800, cdj 1000's , 900 nexus, headphones etc.) my entire professional dj career and I've never had problems. Thanks for any help.
