Use CAT5 UTP
or STP cable to
connect audio/video
equipment.
Transmit color video
up to 2200 feet (670.6 m)
or black-and-white
video up to 2500 feet
(762 m).
Use the Video CCTVA/V Hub to run two
baseband Composite
video and two audio
signals to eight
different locations.
S-Video models
available, including
one with dual audio.
C
oaxial video cable is expensive.
The farther you have to run it,
the bigger the bite it takes out of
your budget. Isn’t there some
cheaper alternative?
Twisted-pair cable, on the
other hand, is more economical.
But its impedance and signal
characteristics differ from those
of coax. You can’t just attach it
directly to video inputs and outputs.
This is when you could use
our Video Baluns and Video
CCTV-A/V Hub. With them, you
can translate your video-only
or video-and-audio signals for
transmission across twisted pair,
so you don’t spend a lot to give
your customers an eyeful!
Video Balun, 1-Way, Video Only
(IC440A)
Use this balun to convert a
single Composite baseband video
signal (such as NTSC, PAL, and
SECAM) from 75-ohm coax cable
Key Features
VIDEO ,AUDIO ,CATV,ANDCCTVBALUNS • VIDEOHUB
to UTP cable. The one-way,
video-only connection is ideal for
connecting security cameras.
Video Balun, 1-Way, Stereo Audio
(IC441A-R2)
This balun converts a single
Composite baseband video signal
(such as NTSC, PAL, and SECAM)
from 75-ohm coax cable to UTP
cable. Additionally, it converts
600-ohm RCA audio signals for
transmission across UTP.
It includes a 10" (25.4-cm)
BNC-male-to-BNC-male coax
cable.
RGB Video Balun (IC442A-R2)
This balun converts a
Composite baseband RGB signal
from coax to three Category 3 or
CAT5 UTP pairs. It includes three
color-coded coax jumper cables.
2-Way Video Mono Audio Balun
(IC443A-R2)
This dual video balun is
designed for standard baseband
audio/video equipment using RCA
connectors for both audio and
video. It has two RCA connectors
for video 1 and 2 and two RCA
connectors for audio.
CCTV Video Balun (IC444A)
Use a pair of CCTV Video
Baluns to transmit Closed-Circuit
TV (CCTV) video signals over a
single Category 3 or CAT5 cable.
This balun has 2-position terminal
screw locks for connection to the
twisted-pair cable.
Video CCTV-A/V Hub (IC445A)
Use the Video CCTV-A/V Hub
to broadcast programs to multiple
monitors throughout your building.
It takes a single video and multiplies it for transmission to each
of the hub’s eight ports. Each port
supports two baseband Composite video and two audio signals.
Or, you can run one S-Video
signal instead of two baseband
Composite signals.

A looping output enables you
to easily connect to other baseband audio/video equipment
such as VCRs, DVDs, audio/video
matrix switches, CCTV cameras,
and monitors.
The Video CCTV-A/V Hub
is compatible with our Video-Only
Balun (IC440A), the Video Stereo
Audio Balun (IC441A-R2), the
Dual-Audio/Video Balun (IC446A),
the S-Video Balun (IC447A), and
the S-Video with Dual-Audio
Balun (IC449A). You need one
balun for the input port and one
balun for each output port.
Dual-Audio/Video Balun (IC446A)
Use this balun in pairs or use it
with the Video CCTV-A/V Hub. The
Dual-Audio/Video Balun extends
two Composite video signals and
two audio signals over CAT5
cable to one other site up to
2200 feet (670.6 m) away.
S-Video Balun (IC447A)
A pair of S-Video Baluns
enables you to to transmit S-Video
baseband signals up to 1000 feet
(304.8 m) across CAT5 cable.
CATV Balun (IC448A)
The CATV Baluns transmit
CATV, VHF, and FM signals over
Category 5 unshielded twistedpair (UTP) cable. The baluns
support CATV channels 2–61, VHF
channels 2–13, and FM broadcast
band channels.
S-Video with Dual-Audio Balun
(IC449A)
A pair of these baluns enables
you to transmit S-Video baseband
and left and right audio channel
signals via UTP cable up to 1000
feet (304.8 m). Use the IC449A with
S-Video equipment such as DVD
players, VCRs, satellite receivers,
MPEG players, laptop computers,
LCD projectors, CCD cameras,
splitters, converters, muxes,
and more!
CCTV Balun, Mini-Coax (IC451A)
Use a pair of these baluns to
link twisted-pair cable between
coax devices. Typical applications
include closed-circuit cameras,
DVRs, monitors, and CCTV
equipment.
CCTV Balun, Passthrough (IC452A)
A pair of these baluns sends
CCTV, low-voltage power, and
2-wire pan/tilt/zoom (PTZ) signals
over twisted pair between two
RS-232 or RS-422 coax devices.
Audio Balun, Analog (IC460A)
Use a pair of Analog Audio
Baluns to link DVDs, VCRs,
camcorders, audio mixers, audio
matrix switches, audio splitters,
distribution amplifiers, boosters,
Hi-Fi, microphones, and home
theaters together using
unshielded twisted-pair (UTP)
cable instead of costly and bulky
coaxial cable.
Audio Balun, Digital (IC461A)
Use a pair of Digital Audio
Baluns to connect a DVD, VCR, or
satellite receiver to a digital audio
home theater using unshielded
twisted-pair (UTP) cable instead
of expensive and bulky coaxial
cable.
Component/Composite Video Balun
(IC462A)
The Component/Composite
Video Baluns enable you to
transmit Component and
Composite video signals over
twisted-pair cable. Without the
balun, you’d have to use three
coaxial cables for a simple pointto-point Component connection.
In a typical application, use a
pair of these baluns to connect
video devices together in home
theaters, conference rooms, or
training centers.
NOTE: All video baluns
must be used in pairs.
Recognize any of these
situations?
• You wait more than 30
minutes to get through to a
vendor’s tech support.
• The so-called “tech” can’t
help you or gives you the
wrong answer.
• You don’t have a purchase
order number and the tech
refuses to help you.
• It’s 9 p. m. and you need help,
but your vendor’s tech
support line is closed.
According to a survey by Data
Communications magazine, 90%
of network managers surveyed
say that getting the technical
support they need is extremely
important when choosing a
vendor. But even though network
managers pay anywhere from 10
to 20% of their overall purchase
price for a basic service and
support contract, the technical
support and service they receive
falls far short of their
expectations—and certainly isn’t
worth what they paid.
At Black Box, we guarantee
the best value and the best
support. You can even consult our
Technical Support Experts before
you buy if you need help selecting
just the right component for your
application.
