I plug my Roland XP-80 into the PA and i take the head phone out and put in in a guitar amp to mouniter it. But it creates a huge hum in the PA, the amp doesent even have to be on to make this hum, its weird. I run the line that goes to the PA through a direct box. Can anyone help me get ride of that hum.
Plug everything into one outlet. Or get a hum eliminator... Or I'm sure someone around here could tell you how to cut sheathing on certain wires, but... Try the first two first.
