A2 Stereo Audio Balun
Installation Guide
Overview
The Intelix A2 balun passively transmits two mono or one
stereo analog audio signal via Cat 5 unshielded twisted pair
(UTP) cable, such as Cat 5. Used in pairs, the A2 transmits
analog audio in either direction up to 2500 feet, providing a
low-cost, versatile cabling solution which uses a building's
existing structured cabling system
Applications
The A2 is ideal for corporate AV, houses of worship, schools,
auditoriums, and virtually any other situation involving
structured audio distribution
Installation
Caution: Do not attempt to open the balun housing. There are no user-
serviceable parts inside the A2. Opening the unit will void your
warranty.
To install an A2 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 A2
are configured properly and labeled appropriately to identify the circuit.
Caution: Do not connect the A2 to a telecommunication outlet wired to
unrelated equipment. Making such a connection may damage the
equipment and/or balun. Please ensure all wiring is “straightthrough.”
3. Verify the desired twisted pairs are not being used for other LAN or telephony
equipment.
4. Connect the RCA inputs from the source equipment to one of the two baluns.
Two A2's are needed--one at each end of the run--and are interchangeable.
Caution: Do not mount the balun over equipment ventilation openings.
Covering the openings may cause the equipment to overheat.
5. Connect a 4-pair Cat 5 cable from the RJ45 8-position modular jack of the A2
to the twisted pair cabling of the building.
6. Connect the second balun's RCA inputs to the destination equipment.
7. Connect a 4-pair Cat 5 cable from the RJ45 8-position modular jack of the A2
to the appropriate modular wall outlet.
8. Power on the source and destination equipment and test for correct operation.
Troubleshooting
If your equipment malfunctions with A2 baluns in place, follow the troubleshooting
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, as shown
below.
3. Check pin configuration.
4. The maximum operational distances over which the A2 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 A2 balun
7. If you still cannot diagnose the problem, call Intelix for support.
with another A2 that is known to be working.
