The Intelix AVO-A4-WP wallplate balun transmits four mono or two stereo analog
audio signals via standard structured cabling, such as Cat 5. Used in pairs or with
the Intelix AVO-A4 rack-mountable balun, the AVO-A4-WP transmit analog audio
in either direction up to 2,500 feet and is ideal for corporate A/V, churches, schools,
auditoriums, and almost any other situation involving audio distribution.
The Intelix AvoCat Series of baluns is the ideal solution for sending audio and
video over structured cabling. When signal quality matters, choose Intelix.
Installation
AvoCat
Series
To install an AVO-A2-WP balun, perform the following steps:
1. Turn off power and disconnect the audio equipment by following the
manufacturer’s instructions.
2. Make certain that outlets and cross connects to which you will connect the AVO-
A4-WP are configured properly and labeled appropriately to identify the circuit.
3. Verify the desired twisted pairs are not being used for other LAN or telephony
equipment.
4. Connect the RCA outputs from the source equipment to the AVO-A4-WP.
Connect the RCA inputs from the receive device to a second AVO-A4-WP or
another compatible Intelix balun, such as the AVO-A4.
5. Connect the two baluns with a structured cable with RJ45 connectors, such as
Cat 5. Verify the cable’s pinout conforms to EIA/TIA 568A or 568B pattern
standards.
6. Power on the source and destination equipment and test for correct operation.
Caution: Do not mount the balun over equipment ventilation openings.
Covering the openings may cause the equipment to overheat.
Caution: Do not attempt to disassemble or alter the balun housing. There are
no user-serviceable parts inside the AVO-A4-WP. Modifying the unit
will void your warranty.
Caution: Do not connect the AVO-A4-WP to a telecommunication outlet
wired to unrelated equipment. Making such a connection may damage
the equipment and/or balun. Please ensure all wiring is “straight-
through.”

Troubleshooting
If your equipment malfunctions with AVO-A4-WP baluns in place, follow the trouble-
shooting procedures below:
1. Perform diagnostics on your audio equipment by following the manufacturer’s
instructions.
2. Check all the connections and the structured cabling system. Verify the RJ45 crimp
pattern conforms to either EIA/TIA 568A or 568B standards.
3. Check the pin configuration of the structured cable.
4. The maximum operational distances over which the AVO-A4-WP can be
transmitted is dependant on the equipment used and cable. Ensure that the
maximum recommended operational distances have not been exceeded.
5. Check that only twisted pair patch cords are being used.
6. Replace the AVO-A4-WP balun with another AVO-A4-WP that is known to be
working.
7. If you still cannot diagnose the problem, contact Intelix for support.
Frequently Asked Questions
How do I expose the individual pairs in Cat 5 cabling?
There is no single method when exposing the four
individual pairs in twisted pair cabling, such as Cat 5
and Cat 6; however, it does help to have a cable
stripping tool designed to strip the cable jacket/
insulation.
Begin by stripping back the cable’s outer jacket/
insulation about an inch (or more depending on
whether multiple baluns will be connected to the pairs
of a single cable) so that the internal wires are exposed.
Be careful not to cut the internal wires when stripping
the insulation/jacket. Eight twisted wires and a string
should now be visible; the string is unnecessary and
may be removed. These eight wires, which when
combined form four pairs, connect directly to the
baluns. Typical protocol pairs similar colors; the
important thing is to verify the same color-coded pairs
are used on each end.
How do I crimp an unshielded RJ45 connector onto Cat 5?
Crimping an RJ45 connector onto Cat 5 is a fairly straight forward task, assuming you have
the proper tools. Keep in mind that baluns require either the EIA/TIA 568A or 568B crimp
pattern, which are the industry standards for networking.
1. First, strip a portion of the insulation about 3/4" to expose the four twisted pairs.
2. Next, untwist the wires and fan them out so that they match either EIA/TIA 568A or
568B pattern.
3. Evenly trim the wires to about 1/2". Most RJ45 crimp tools feature a built-in wire
trimmer.
4. Insert the trimmed wires into the RJ45 connector so that each wire is in its individual
slot. Verify each wire is completely inserted.
5. Finally, insert the RJ45 connector into the crimp tool and squeeze firmly.
6. Repeat the above steps on the other end of the Cat 5 cable and verify pinout is iden-
tical on each end.
