Intelix AVO-MIC-F Microphone Balun Set
Installation ManualInstallation Manual

Installation 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.
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.
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.
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.
Installation
Caution: Do not attempt to open the balun housing. There are no user-serviceable parts
inside the AVO-MIC-F. Opening the unit will void your warranty.
Caution: Do not mount the balun over equipment ventilation openings. Covering the
openings may cause the equipment to overheat.
AvoCat
Series
Caution: Do not connect the AVO-MIC-F 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.”
