What is the maximum recommended distance that an rca cable can be run before any issues may arise? Reason I ask is because I'm considering purchasing some powered surrounds and a second sub and my avr has only unbalanced outs. So, I'd have to run an rca cable about 30' for one of the surrounds, 50-55' for the surround and 50' for the sub. Well, I'd probably run xlr cables in-wall but it's not like that would make it balanced. I'd really appreciate any advice on this subject.

The maximum distance you can run unbalanced noise-free depends entirely upon your local electromagnetic environment and how the cables are placed.


Just run temporary RCA cables and see if it works. If you're getting hums, pops or other noises, look into options such as the baluns mentioned above.

I wouldn't use unbalanced interconnect for more than 15-20'. They may pick up too much hum. I recommend to take one cable and try. If result is not acceptable, get something like this http://www.mcmelectronics.com/produc...8485-/555-8485 (you probably need two of them).

You might consider getting some baluns and running cat 5.

That's a pretty nice idea. Kinda pricey considering the surrounds were only $350 for the pair but if it works then it works. Thanks Michael.

I'll give an unbalanced run a shot since I have a 60' rca cable from way back when and see how it goes. If it doesn't work I'm leaning toward the balun.


Thanks a bunch for all the help guys. I really appreciate it.
