Installation
To install the Stereo Hi-Fi Baluns, perform the following steps:
1. One pair of Stereo Hi-Fi Baluns is required for each stereo channel.
2. Identify the pin configuration of the baluns. Two (2) twisted pairs are required as
shown in the following diagram.
Note: The Stereo Hi-Fi Balun is phase polarity sensitive. Therefore, in order to
achieve full stereo audio quality, please ensure that the wiring is straight-
through and according to EIA568 (A or B) standard.
3. Verify the colors of the RCA plugs and connect one (1) Stereo Hi-Fi Balun to the
left-audio and right-audio RCA connectors of the audio source.
4. Verify the colors of the RCA plugs and connect a second Stereo Hi-Fi Balun to the
left-audio and right-audio RCA connectors of the audio receiver at the remote end.
5. Complete the connection between the two (2) baluns, using standard UTP cable,
connector blocks and appropriate modular RJ45 outlets.
6. Power-on the audio equipment and check the audio quality. The audio should be
clear within the maximum specified distances. The following diagram shows a
typical configuration.
Troubleshooting
The following table describes some of the symptoms, probable causes and possible
solutions in respect to the installation of the Stereo Hi-Fi Balun:
Symptom Probable Cause 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 continuity
No audio
Defective balun
Change Stereo 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.
