Ground Loop Isolator Question
I am having the same whine associated with my Zune + cigarette lighter + aux line as many others have had.
I see everyone saying to buy a ground loop isolator for the fix, but I had a simple question.
The isolator I see at Radio Shack has 2 male and 2 female RCA jacks, with the males being the input side and the females being the output side (doesn't make sense to me). Does it matter if I turn it around and use the female side as the input (so I can plug my 3.5mm -> RCA cable from my dock) and the male as the output (to my stereo)? Will the ground loop isolator work the same if I switch it?
