Home theater wiring question : Separation
 
I understand the importance of separating the 110/220 V wiring from audio cables to reduce the chance of noise and other interference, but I am wondering if it is equally important to separate the signal cables (RCA) from the speaker wire themselves, or can I run these together? Obviously they go to the same location anyway on one end.

The low voltage wiring can all be next to each other. Majority of the time, RG-6 is used for all audio & Component wiring, Cat-6 is used for HDMI these days.

I wouldn't worry about keeping anything separated...

The only thing I would worry about is if you are running low level analog signal cables, i.e. RCA, VGA, component, composite tightly bundled with 120v wires for an extended distance, i.e. >5 feet. I worked installing home theatres, and we would run into issues very rarley, but sometimes with analog video (i.e. not HDMI, DVI etc...) when we would do a TV mounted over a fireplace etc... and the power cables were running with the analog video cables for most of the run.

But today most video is digital, so it either makes it there or it doesn't, so don't worry about it for video if you're doing digital. Speaker cable is basically impervious to noise. What you have to worry about is the very low voltage audio, i.e. running sources from the house out to a pool house (long runs) with high voltage power (not speaker) right next to it. But then again if you're outside, it probably doesn't matter if you get a little less fidelity, it's not going to be a big deal.

Don't worry if you're just running wires across each other in a home theater situation, but don't run low voltage analog signals parallel with power for >5 feet.

That's my $.02 from working as a whole house/theatre tech for a few years in college.

The other answers about not needing to worry are right. Put a couple article website links thought you might find useful. Let me know if I can help out. The last link is just a "just for kicks link"
