Quick Installation Guide
Overview
The Analog Audio Balun Amplifier allows one (1) analog source using the Muxlab
Audio Balun (500028) or Muxlab Audio Matrix Switch (500210) to feed a 30W/channel stereo amplifier using UTP Cat5e/6 cable.

Installation
One source using a Muxlab Audio Balun (500028) or a Muxlab Audio Matrix (500210) is needed to complete the connection via UTP cable.
Caution: Do NOT connect any output wire together or to the ground.
Do not block the ventilation holes.
Do not connect the unit to a telecommunication outlet wired to unrelated equipment. Making such a connection may damage the equipment and/or the balun. Verify that the desired twisted pairs are not being used for other LAN or telephone equipment.
Do not attempt to open the housing. There are no user-serviceable parts inside the amplifier. Opening the unit will void your warranty.
1. Use a 4-pair Cat5/5e/6 cable between the source and the amplifier. Patch panels are allowed.
2.
Verify the wiring is “straight-through”, has 4 twisted pairs and has the standard Ethernet
RJ45 connector.
3. It is recommend to use the unit with speakers with impedance of 8 ohms and a rating of
50W minimum. Higher impedance will work but less power will be available but lower can overheat the unit.
4. Use wires with at least 18 AWG to connect the binding posts to the speaker. Any standard electrical wire with minimum gage is acceptable but bigger is better. Limit the distance to less than 15ft (5m).
5. Turn the front button to adjust the volume. You should see the lowest bar moving.
6. Push the front button to save the default volume at power-up. A small ‘M’ should appear near the volume symbol ‘((o))’ until you turn the button again.
Troubleshooting
The following tables describe some of the symptoms, probable causes and possible solutions regarding the unit:
Symptom Probable Cause
No audio
Loss of Hi Frequency
Hum or Buzz
Sound chopped or cut
No continuity
Volume off
Equipment off
Exceeded distance
Defective cable or equipment incorrectly connected or grounded.
Volume too loud
Overheat unit
Possible Solutions
Check continuity on each pair.
Check if pairs are not swapped or reversed.
Check if the four pairs are present.
Check display to see the input level and turn the front volume.
Check the audio source equipment.
Verify total cable length.
Change cable or verify wiring interface.
Try grounding equipment on each side to safety ground.
Check display.
Place the unit in a ventilated area.
Speaker impedance too low.
If you still can’t diagnose the problem, please call MuxLab Customer Technical Support at
