Our take on the Niles C5-A2WM

by Amanda P.
Niles

If you're putting together a multi-room audio system that involves longer cable runs between rooms, check out the Niles C5-A2WM. This clever device uses durable, inexpensive CAT-5 cable to send stereo audio signals to another room in your house. Plus, it installs neatly in your wall for a décor-friendly look.

The 'A2WM 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 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-A2WMs, or pair one with a small component-style model. Installation is straightforward — just connect them both to in-wall CAT-5 cable, then mount them into your wall. Place one in your main listening room, and connect a CD player, satellite radio, or other stereo audio source. Install the other in your remote listening area, and hook it up to a table radio or powered home audio system via its stereo audio jacks. Now you can send audio signals from your main room to your secondary room.

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-A2WM balun converts audio signals between balanced CAT-5 connections and unbalanced RCA audio connections.

Features

Product Overview: The C5-A2WM is a transformer (Balun) to convert a CAT-5 signal to analog stereo audio, and vice versa. Typically two are used at opposite ends of the signal path; one unit converts the audio source to CAT-5 for transmission over a long distance, a second unit converts the CAT-5 signal back to analog audio to feed a remote audio system.

Mounting: The Balun is designed to fit into a single gang J-box using the included wall plate. Multiple insert plates can be mounted in larger J-boxes using Decora-style wall plates designed to cover multiple gang J-boxes.

Input/Output

Analog Audio: The female RCA stereo jacks on the front of the C5-A2WM can be used as an input and converted to CAT-5, or as an output to feed an audio component.

CAT-5: The RJ-45 jack on the back of the unit can be used as an input and converted to stereo audio, or as an output to feed the network.
