Is a special cable required to connect the digital audio coaxial input? Can I use RG6 cable terminated with rca connectors? My satellite receiver is located in my future theater room but I want to feed the digital audio signal to my htib system in my living room approx 30 ft away.

Specs for digital audio cables are virtually the same for video. So any good video cable would work fine in the situation. :) I personally have had really good luck with Belden and would recommend a look.

Absolutely. In fact, this can possibly make for a better cable than one that's made specifically for this purpose.

Thanks everyone.
