I have a customer who wants to send the output of their recevier in their living room, to the input of their receiver at the pool house. around 500 feet away. The customer has a music server, Xm, etc, they would like to be able to listen to at the pool house. I was just wondering what my options would be for the type of wire.

Off the top I woud use Cat5 with an Audio control 4 channel driver and receiver BLD 10 and BLR 10 respectively. Add an additional Cat5 for control and another Cat5 just in case and you are done.

Muxlab also makes some good baluns. audio, composite video, s-vid and component over cat-5. Priced good too.

I do wiring in highend recording and broadcast facilities and 500 is not always uncommon. If you use a 24 or 22 guage line level cable you should have no problem. They run line level in stadiums and like facilities sometimes up to 2000'

LiveWire, is that for unbalanced or balanced connections?

I have used the Audio Control stuff before, but didn't know if it would reach. Thanks.

I am assuming on using RS232 for control because of the long distance. The only pieces I need to control is the polk XM, Escient E2, and Denon AVR. Again, RS232 over 500 feet will not be a problem? THanks guys.

Shoe: that would be balanced if you need unbalanced you can use balancing/unbalancing transformers,

you can also run the audio down a coaxial cable like RG-6 instead of linelevel

The Audio Control is speced for up to 1000'. RS232 is also usually speced as 50' max but I've gone longer but no where near 500', maybe 100-125 but it was heavier awg than Cat5. There are extenders for long distance RS232 communication but I haven't needed them myself. I recently did a tad over 400' with a URC MRF300 and RFX150 and the MX850 works about 100' from the RFX150 so that combo may work for you.

I am assuming that the RS-232 is handled by a local device that will be fed from the master processor by an IP, Netlinx (AMX), or CresNet (Crestron) signal.

LiveWire was right on the money.
Balanced line level can be noise-free for LOOONG distances.

Think about the runs between the mics and/or DIs and the console at a concert... and then back to the stage for the racks full of amps to drive those big arrays...

So, now the choice is whether to run CAT5 or shielded line level cable... Line level will allow a longer run, but CAT5 is more flexible if you need to mix up the application down the road (as in an IP solution).

I would go CAT5...

RS-232 is indeed limited in its transmission length, but there is another similar standard meant for going distances like 500 feet. RS485, RS422, RS423 result from a google search. I think 485 is the standard you are looking for, and there are devices that translate from 232 to 485.

this may sound stupid but Sonance has the LS-1 & LR-1 that convert a stereo line level unbalanced signal into a stereo balanced signal. It is capable of cgoing I think up to 1000 or so feet.

I will be using the SPLCD6.4v and will be using the RS422 out into a RS232 connecting block, then taking the RS232 into the RS232 1x8 router. Thanks for all your help.
