Intelix AVO-MIC-WP-F Microphone Balun Set
The Intelix AVO-MIC-WP-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-WP-F balun set includes a decora-style wallplate send balun,
rack-mountable receive balun, and a power supply; the set is powered on the receive end.
The AVO-MIC-WP-F balun set is ideal for corporate A/V, churches, schools, auditoriums,
and almost any other situation involving microphone level audio signal distribution.
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-WP-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. The pin configuration follows the EIA/TIA
568A/B standard. Please ensure that wiring is straight-through.
2. Connect the AVO-MIC-WP-F send balun to the audio output of the audio source
using an audio cable.
3. Connect the AVO-MIC-WP-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 the wallplate send 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
8. On the send balun, select whether phantom power is engaged or not (phantom
power is on when the switch is down). Then adjust the overall system gain
between 0 and 60 dB.
Caution: Do not attempt to open the balun housing. There are no user-serviceable parts
inside the AVO-MIC-WP-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.
Caution: Do not connect the balun 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.”
