If you're putting together a multi-room audio/video system that involves longer cable runs between rooms, check out the Niles C5-VA2. This clever device uses durable, inexpensive CAT-5 cable to send standard-definition composite video and stereo audio signals to another room in your house. It's a great option for homes with an existing CAT-5 network, since you won't have to install any new in-wall wire. And it delivers full, clear sound and crisp video, even over cable runs of up to 2,200 feet.
How it works
You'll need to purchase two baluns to set up a fully functioning system. You can use two C5-VA2s, or pair one with an
in-wall model. Connect the first one to a cable box, DVD player or other A/V source in your main room, and plug it into a nearby CAT-5 outlet. Next, connect your second C5-VA2 to a CAT-5 outlet in your remote room. Then hook it up to a TV and A/V setup via its composite video and stereo audio jacks. The compact C5-VA2 doesn't require AC power, and it's wall-mountable for flexible placement.
What is a balun?
A balun gets its name by converting signals between balanced and unbalanced lines. Balanced cables can carry signals over much larger distances than unbalanced lines, because of their superior noise rejection. The C5-VA2 balun converts composite video and stereo audio signals between balanced CAT-5 connections and unbalanced RCA connections.
