I wonderee about the same thing, but I have a friend who has run a rig like that for years and his audio sounds fine. Besides, just happened to think, he may be using shielded cable which is sometimes used in networks. I suppose it would depend on the environment, but remember, these are also low impedence mikes any more. Didn't work for you, did for my friend, what can I say. 73s Butch Bussen wa0vjr
