Installation ManualInstallation Manual

The Intelix AVO-MIC-F microphone balun set transmits a preamplified microphone
signal and phantom power up to 2,500 feet over standard structured cabling, such as Cat

5. The AVO-MIC-F balun set includes a rack-mountable send balun, rack-mountable
receive balun, and a power supply; the set may powered on either the send or receive end.
The AVO-MIC-F balun set is ideal for corporate A/V, churches, schools, auditoriums, and
almost any other situation involving microphone level audio signal 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

Caution: Do not attempt to open the balun housing. There are no user-serviceable parts

To install an AVO-MIC-F balun, perform the following steps:

1. Identify the pin configuration of the baluns. Two (2) twisted pairs are required:
one for audio and one for power (if powering either balun remotely). The pin
configuration follows the EIA/TIA 568A/B standard. Please ensure that wiring is
straight-through.

2. Connect the AVO-MIC-F send balun to the audio output of the audio source using
an audio cable.

Caution: Do not connect the AVO-MIC-F to a telecommunication outlet wired

3. Connect the AVO-MIC-F receive balun to the audio input of the audio destination
using an audio cable.

4. Complete the connection between the two baluns using standard twisted pair
cable, such as Cat 5. Verify the Cat 5 is terminated with RJ45 connectors on both
ends which conform to the EIA/TIA 568A or 568A crimp standards. Ensure that
there are no split pairs or taps.

Caution: Do not mount the balun over equipment ventilation openings. Covering the

5. Connect the included power supply to either the send or the receive balun.

6. Power-on the audio equipment.

7. On the receive balun, EQ the balun pair by selecting the overal distance of the
system. Set the EQ switch to either less than or equal to 1,500 feet or greater than
1,500 feet.

8. On the send balun, select whether phantom power is engaged or not. Then
adjust the overall system gain between 0 and 60 dB.

openings may cause the equipment to overheat.

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
identical on each end.

Troubleshooting

If your equipment malfunctions with AVO-MIC-F 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.

3. Check the pin configuration on the structured cable.

4. The maximum operational distances over which the AVO-MIC-F 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-MIC-F balun with another AVO-MIC-F that is known to be
working.

7. If you still cannot diagnose the problem, contact Intelix for support.

System Drawing: A podium microphone is routed to a remote receiver via an
Intelix AVO-MIC-F balun set. The baluns transmit the signal over 2,500 feet of
standard Cat 5 cabling. The system is powered on the receive end.
