    I have RCA cables for audio from my cable box to my TV. Could I get a y adapter and run one set to my TV, and the other to my whole house audio system?

    If so, how far can I run RCA audio cables? I would probably need 100ft. Where is a good source for that length?

    Thanks

    Bob

    Are you talking about an RCA cable or a video cable?

    They're analogue audio cables. I would like to be able to listen to TV sound in other rooms.

    OK, How far can you run analogue audio? Is 100 ft a problem?

    Sorry...

    This is a question that has no guaranteed easy answer. Consider the following link http://www.epanorama.net/documents/a...le_length.html which discusses the issues that are at hand.

    Short of contacting your cable company for their opinion, my safest, cost effective recommendation is to go down to Radio Shack and get 100 ft of coax that's preterminated in F-Connectors. While you're there, pick up some F to RCA connectors and try it. If it doesn't work, RS will allow you to return the items and get your money back. If it does and you find it acceptable, then you're home free. In this particular case, I'd not recommend purchasing some high quality, low capacitance coax. Likely you'd have to order it, and if that also doesn't work, then you're out s/h which will be substantial on that amount. Also possibly a restocking fee.

    Let us know if this works out for you.

    I’ve never had any problem running line-level signals this length, Bob. The “concerns” are minimal at best – slight signal loss (which can be recovered with the volume control on the other end) and slight high-frequency loss (ditto, with the treble control). Typically long runs like this are to secondary areas where sound quality is likewise a secondary concern to the afforded convenience.

    The most critical aspect is the wire used. You will want cable with excellent shielding to minimize the potential for EMI or RFI. As much budget so-called audio cable has poor shielding, the coaxial cable Chu recommended is ideal for the job.
