Ok this problem is driving me crazy to figure out , can anyone help
I have a 12 chan stero none powered desk , this is connected to a stage snake , I have 1 amp for front house speakers and one for monitors , I usually connect a cd player or laptop strength into one of the channels by 1/4 inch jack the other end connects into the cd/ computer . Inbetween this cable I have a ground loop.
Ok so that's the background now the problem is when playing a music cd through the desk the slider won't turn the volume down I have to adjust the volume by the main speaker / monitor slider, they keyboard and mics adjust fine with their individual channel sliders.
Anyone got any ideas? Thanks jay
