Quad Audio Balun (IC565A)
Installation Guide
Introduction
The Quad Audio Balun allows up to four (4) analog line audio signals to be transmitted
via unshielded twisted pair (UTP) cable in a point-to-point connection. Used in pairs,
the Quad Audio Balun eliminates up to four (4) coaxial cables, allowing audio-video
equipment to be connected via space-efficient and cost-effective Category 5 twisted pair
cable. The Quad Audio Balun also works in conjunction with other Black Box analog
audio baluns such as the IC460A.
Installation
One (1) pair of baluns support four (4) mono unbalanced analog audio channels or two (2)
stereo audio channels via Cat5 twisted pair. To install the baluns, perform the following
steps:
1.
Identify the pin configuration of the baluns. Four (4) twisted pairs are required
if all four (4) signals are transmitted. The pin configuration follows the
EIA/TIA 568A/B standard. The Quad Audio Balun is reverse polarity
sensitive. Please ensure that wiring is straight-through (Ring to Ring, Tip to
Tip).
2.
At the audio source end, connect a Quad Audio Balun to the audio output using
the appropriate number of RCA cables.
3.
At the audio receiver end, connect a Quad Audio Balun to the audio input using
the appropriate number of RCA cables.
