Quick Installation Guide

Overview

The Quad Audio Balun allows up to four (4) analog line audio signals to be transmitted

via an unshielded twisted pair (UTP) cable in a point-to-point connection. Used in pairs,

the Quad Audio Balun eliminates up to four (4) coaxial cables, allowing audio-video

equipment to be connected via a space-efficient and cost-effective Category 5E/6

twisted pair cable and supports Hi-Fi audio signal transmission. The Quad Audio Balun

also works in conjunction with other MuxLab analog audio baluns such as the 500019.

Installation

One (1) pair of baluns supports four (4) mono unbalanced analog audio channels or two

(2) stereo audio channels via a Cat 5E/6 twisted pair. To install the baluns, perform the

following steps:

1. Identify the pin configuration of the baluns. Four (4) twisted pairs are required if

all four (4) signals are transmitted. The pin configuration follows the EIA/TIA

568A/B standard. The Quad Audio Balun is reverse polarity sensitive. Please

ensure that wiring is straight-through (Ring to Ring, Tip to Tip).

2. At the audio source end, connect a Quad Audio Balun to the audio output using the

appropriate number of RCA cables.

3. At the audio receiver end, connect a Quad Audio Balun to the audio input using the

appropriate number of RCA cables.

4. 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.

5. Power-on the audio equipment. Check the sound quality and refer to the

troubleshooting table below if the sound quality is unsatisfactory. The following

diagram shows a typical installation.

Troubleshooting

The following table describes some of the symptoms, probable causes and possible

solutions in respect to the installation of the Quad Audio Balun:

Symptom Probable Cause Possible Solutions

EMI interference Check that wiring is not too close to transformers

and ballasts.

Poor Quality Audio

Split pair Check if the UTP pairs are split and correct.

Each signal pair must be twisted.

Power-off Check power supply.

Open contact Check wiring to ensure continuity.No Audio

Defective Audio Balun Change Audio Baluns for another pair.

Distance exceeds specs

Check DC loop resistance and verify if distance

spec is exceeded.

Reduce cable length or eliminate high-loss

components.Weak Audio

Lower grade UTP cable

is introducing high

signal losses.

Use signal repeater for extended distance.

Replace cable by higher grade.

If you still cannot diagnose the problem, please call MuxLab Customer Technical

Support at 877-689-5228 (toll-free in North America) or (+1) 514-905-0588
