If you're putting together a multi-room audio system that involves longer cable runs between rooms, check out the Niles C5-A2. This clever device uses durable, inexpensive CAT-5 cable to send 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, even over cable runs of up to 2,500 feet.
How it works
You'll need to purchase two stereo audio baluns to set up a fully functioning system. You can use two C5-A2s, or pair one with an
in-wall model. Connect the first one to a CD player, satellite radio, or other stereo audio source in your main listening room, and plug it into a nearby CAT-5 outlet. Next, connect your second C5-A2 to a CAT-5 outlet in your remote listening area. Then hook it up to a table radio or powered home audio system via its stereo audio jacks. The compact C5-A2 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-A2 balun converts audio signals between balanced CAT-5 connections and unbalanced RCA audio connections.
