Thx slippery for the link. Exactly as I expected. Just needed a little verification I guess. It's not a loooong run though. It's 20 or 25 feet. This ht is in my bedroom Just about any cable is shielded of course. I am not going to make my own from speaker cable.
If you can come up with a better way, please holler! My computer sound, in another room has an FM transmitter so I can work outside in the yard or on my truck and still listen to whatever is on my main system tv or computer. I use a small radio shack amp just as switching unit before the transmitter for that. So if it was audio from my computer system, I'd be covered of course.
