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
Possible Solutions
No audio
No continuity
Check continuity on each pair.
Check if pairs are not swapped or reversed.
Check if the four pairs are present.
Volume off
Check display to see the input level and turn
the front volume.
Equipment off
Check the audio source equipment.
Loss of Hi Frequency
Exceeded distance
Verify total cable length.
Hum or Buzz
Defective cable or
equipment incorrectly
connected or grounded.
Change cable or verify wiring interface.
Try grounding equipment on each side to
safety ground.
Sound chopped or cut
Volume too loud
Overheat unit
Check display.
Place the unit in a ventilated area.
Speaker impedance too low.
