If you're putting together a multi-room audio system that involves longer cable runs between rooms, check out the Niles C5-DA. This clever device uses durable, inexpensive CAT-5 cable to send digital audio signals to another room in your house.
The 'DA is 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 crisp, detailed sound, even over cable runs of up to 600 feet.
What is a balun?
A balun gets its name by converting signals between balanced and unbalanced lines. Balanced cables can carry signals over much longer distances than unbalanced lines, because of their superior noise rejection. The C5-DA balun converts audio signals between balanced CAT-5 connections and unbalanced coaxial digital audio connections.
