Muxlab Analog Audio Balun - Manual (Page 2)

3. Identify the pin configuration of the baluns. One twisted pair is required for
each audio balun connection. The Audio Balun is polarity sensitive. Therefore
stereo audio applications, for full stereo audio quality, please ensure straight-
thru polarity as shown in the next diagram.

4. The Audio Baluns work in pairs. Plug one Audio Balun into the RCA
connector of the audio source equipment. If stereo audio is being transmitted
connect one Audio Balun to Audio-Left and one Audio Balun to Audio-Right as
shown in the photo below.
5. Plug a second Audio Balun into the RCA connector of the audio receiver
equipment at the remote end. If stereo audio is being transmitted connect one
Audio Balun to Audio-Left and one Audio Balun to Audio-Right as shown in
the photo below.
6. Complete the connection between the two baluns, using standard UTP cable,
connector blocks and modular wall outlets.
7. Power-on the audio equipment and check the audio quality. The audio should
be clear within the maximum specified distances.

Troubleshooting
The following table describes some of the symptoms, probable causes and possible
solutions in respect to the installation of the Analog Audio Balun. If you still cannot
diagnose the problem, please call MuxLab Customer Technical Support at 877-689-
5228 (toll-free in N.Am) or 514-905-0588 (Intl).
Symptom Probable Causes Possible Solutions
Poor audio quality 1. EMI interference. Check that wiring is not too close to
transformers and ballasts.
2. Split pair Check if the UTP pairs are split and
correct. Each signal pair must be twisted.
No audio 1. Power-off. Check power supply.
2. Open contact Check wiring to ensure continuity
3. Defective Audio Balun Change Audio Baluns for another pair.
Audio weak 1. Exceeded distance
specifications
Check DC loop resistance and verify if
distance spec is exceeded. Reduce cable
length or eliminate high -loss components.
2. Lower grade UTP cable is
introducing high signal
losses.
Use signal repeater for extended distance.
Replace cable by higher grade.
