Quad Audio Wall Balun

500033-WP-UK

Quick Installation Guide

Overview

The Quad Audio Wall Balun (500033-WP-UK) allows up to four (4) analog line audio
signals to be transmitted via a single Cat 5E/6 cable in a point-to-point connection. Used in
pairs, or in conjunction with the 500033, the Quad Audio Wall Balun features full audio
bandwidth response for high fidelity applications and features built-in color-coded RCA
connectors for ease of installation. The Quad Audio Wall Balun also works in conjunction
with other MuxLab analog audio baluns such as the 500019. Applications include; Audio
distribution, high-fidelity sound systems, and custom residential audio systems.

One (1) pair of baluns is needed to complete one quad audio connection via Cat 5E/6 twisted
pair. To install the baluns, perform the following steps:

1. Identify the pin configuration of the baluns. One (1) twisted

pair is required for four (4) analog line audio signals. The pin
configuration follows the EIA/TIA 568A/B standard. The
Quad Audio Video Balun is reverse polarity sensitive. Please
ensure that wiring is straight-through (Ring to Ring, Tip to
Tip).

2. To install the balun in a single back box, choose a back box

with a depth of 40 mm or more. Connect the RJ45 plug into
the rear of the balun. Secure the balun with the 2 front screws.

3. Plug one (1) balun into the stereo audio outputs of the video

source(s) according to the color code of the RCA connectors.

4. Plug the second balun into the stereo audio inputs of the receiver(s) at the remote end.

5. Complete the connection between the two baluns, using standard Cat 5E/6 twisted pair

cable and connecting hardware, terminated by RJ45 plugs at both ends. Ensure that
there are no split pairs or taps.

6. Power-on the audio equipment. The audio should be clear within the maximum

specified distances. The following diagram shows a typical configuration.

7. To mount the wall plate balun in a gang plate, you must first remove the 4 rear screws,

then remove the balun. Next unclip the balun front plastic panel.

8. Clip the front plastic panel to a standard gang plate and secure the

balun using its 4 screws. Multiple wall baluns can be mounted side
by side on a gang plate.

Troubleshooting

The following tables describe some of the symptoms, probable causes and possible
solutions in respect to the installation of the Quad Audio Balun. If you still cannot
diagnose the problem, please call MuxLab Customer Technical Support at 877-689­5228 (toll-free in North America) or ([phone] (International).

Symptom Probable Cause Possible Solutions

Check that wiring is not too close to transformers
and ballasts.
Check if the UTP pairs are split and correct.
Each signal pair must be twisted.

Check DC loop resistance and verify if distance
spec is exceeded.
Reduce cable length or eliminate high-loss
components.

Use signal repeater for extended distance.
Replace cable by higher grade.

Poor Quality Audio

No Audio

Weak Audio

EMI interference

Split pair

Power-off Check power supply.
Open contact Check wiring to ensure continuity.
Defective Audio Balun Change Audio Baluns for another pair.

Distance exceeds specs

Lower grade UTP cable
is introducing high
signal losses.
