So I have couple of mixers, and one of my portable mixers, (behringer q1202 usb), i never came across this issue
 
anyways when I connect it to a power source the compressor lights are all lit up, and the audio is unusable with a distortion. I feel like i don't knowhow i am able to trouble shoot this...
 
does anybody know this issue, if so, how do i fix it.
 
thanks!
