[QUOTE="Dan Mortensen, post: 123249, member: 2826"] Re: CARE TEAM - need help. Audio Dropouts on AES50 Although I don't really want to start a fight, every single thing in this post is wrong IMHO. Phase schmase. Having the PA across several phases of the same supply with the same ground has no effect on modern equipment. Having different ground references can have an effect, but that's not what you're saying. This is exactly wrong, because the shield's purpose is to protect the cable innards from Electro Static Discharge, which can happen on either end of the cable. If you have your stage and FOH devices on the same ground reference, ground loops will not occur but ESD will, eventually.
