Hi. I would like to have a satellite headphone station that sits about 20+ft away from my rack where my Premier DAC, Digital Director and home theater components are located. I would run xlr cables from the rack thru the wall and come up in a floor connection with xlr and power outlet. I am worried about various kinds of RF interferences as it is in a theater with subs in the wall and LED lighting throughout. It will be on a different circuit than the rack and I am concerned about a ground loop issue any insight you have anyone has will be helpful. Thanks.
