sound problem with new setup

sound problem with new setup

The problem is iv getting some feedback sounds like crackling sounds i thought it was the speakers so i turned them off but was still getting them through headphones 2. Volume was not that high.

Here is list of what i have 2*cdj 2000 ,djm 400 mixer , traktor control x1 running through traktor pro 2

Any ideas ???

Are you able to isolate the noise to one channel or do you hear it no matter what?

i think its on both not 100% sure though will check tomorrow and find out
