Reply to Kontrol S4 issue with Live PA

Hi guys.

Having an issue where if I try to do scratching on the jogwheels, the speakers have some distortion or noise. I tried jogwheeling on a channel that wasn't on air, even with filter at 100%, it seemed to 'lag' or slow down the playing channels audio + continue to distort. I'm running a laptop to the S4, as well as a X1. I'm using the TRS outputs to a pair of RCF 310A's with XLR cables.

Any assistance would be great as my scratching last evening was embarassing! :P

Btw I'm running the current Traktor Pro S4, was hoping to rectify this problem before upgrading to T2.
