S-Video / Hi-Fi Wall Balun
500038-WP-US
Quick Installation Guide
Overview
The S-Video/Hi-Fi Wall Balun allows one S-Video signal and one hi-fidelity stereo
audio channel to be transmitted via an unshielded twisted pair (UTP) cable in a point-to-
point connection for more versatile cabling. Used in pairs, or in conjunction with the
500038, the S-Video/Hi-Fi Wall Balun eliminates costly and bulky S-Video and audio
cable, allowing S-Video equipment to be connected or moved to any convenient
modular outlet. The S-Video/Hi-Fi Balun also works in conjunction with MuxLab’s
Audio/Video Distribution Hub (500200) to allow S-Video programming to be
distributed via UTP. Applications include: Classroom video distribution, commercial
and home audio/video systems, hospital video training, video conferencing, and video
kiosks.
Installation
One (1) pair of baluns is needed to complete one composite stereo audio-video
connection via Cat 5E/6 twisted pair. To install the baluns, perform the following steps:
1. Identify the pin configuration of the baluns. Two (2) twisted
pairs are required for S-Video and two (2) twisted pairs are
required for stereo analog audio. The pin configuration
follows the EIA/TIA 568A/B standard. The Stereo Hi-Fi
Video Wall 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. Place a Decora® faceplate (not included) and secure with
the 2 front screws.
4. Plug one (1) balun into the S-Video/stereo audio output of
the video source according to the color code of the RCA
connectors.
5. Plug the second balun into the S-Video/Hi-Fi Wall Balun input of the video screen
or receiver at the remote end.
6. Complete the connection between the two baluns, using standard Cat 5E/6 twisted
pair cable and connecting hardware, terminated on RJ45 plugs at both ends. Ensure
that there are no split pairs or taps.
7. Power-on the audio-video equipment. Check the image quality and refer to the
troubleshooting table below if the image quality is unsatisfactory. The following
diagram shows a typical installation.

Troubleshooting
The following tables describe some of the symptoms, probable causes and possible
solutions in respect to the installation of the Stereo Hi-Fi Video Wall Balun:
Video Symptom Probable Cause Possible Solutions
No continuity in video
link
Verify cable continuity between pairs of
baluns.
Power off Check power supplies of video equipment.No video
Improper connection
and/or swapped pair
Check that baluns are connected to correct
video inputs and outputs.
Unusual colors Reversed polarity Check wiring and ensure straight-through
polarity
Background
pattern EMI interference
Identify possible radiating frequency sources
(i.e., wireless LANs, switching power
supplies). Try to isolate them from the video
connection. Use shielded twisted pair grounded
at both ends.
Smearing Exceeded distance Verify cable grade. Use higher-grade cable if
necessary.
Exceeded distance Verify cable grade. Use higher-grade cable if
necessary. Increase contrast on monitor.
Weak contrast
Unusual link attenuation Verify cable distance using ohmmeter or cable
tester.
Image not stable Defective link or
equipment Verify video equipment interface integrity.
Horizontal bars
moving slowly
Substantial crosstalk
between multiple video
sources
Consecutively turn off other video sources to
determine which video source is the cause of
interference.
Snowy picture Distance is near limit Verify cable grade. Use higher-grade cable if
necessary. Reduce color intensity at monitor.
Audio Symptoms Probable Causes Possible Solutions
EMI interference Check that wiring is not too close to
transformers and ballasts.
Poor audio quality
Split pair Ensure that the UTP pairs are not split and that
each pair of wires is twisted.
No power Check your audio system for power.
Open circuit Check wiring to ensure continuityNo audio
Defective balun Change S-Video/Hi-Fi Baluns for another pair.
Audio phase
cancellation Reversed wires Check for straight-through wiring.
Audio weak Distance specifications
exceeded
Check DC loop resistance and verify if distance
spec is exceeded. Reduce cable length or
eliminate high-loss components.
