INSTALLATION AND OPERATION
MODEL: PHASE EIGHT+
DISTRIBUTION AMPLIFIER
INTRODUCTION
The information in this manual covers the in-
stallation, operation, and maintenance of the
PHASE EIGHT Model
Distribution
Amplifier.
This unit should be installed using approved
materials and wiring practices in accordance
with national, state, and local electrical codes
and ordinances.
The
Distribution Amplifier provides six
identical video outputs from a single video in-
put. Circuitry utilizes individual complemen-
tary transistor pairs, providing six isolated video
output signals intended for
loads.
The amplifier circuitry is housed in a PHASE
EIGHT module, encased in
a
protective cover,
and is designed for installation in the PHASE
EIGHT rack system.
INSTALLATION
In the basic
configuration, the output
from one video source (camera or switcher) is
fed to the input connector of the distribution
amplifier, and six outputs from the
are
cabled directly to the input connectors of six
separate pieces of video equipment (monitors or
recorders). See Figure 1.
The V2
may also be used in more complex
systems. Figure 2 illustrates a branching video
system, in which video from a single camera can
be viewed at multiple locations. Monitors and
video devices cabled for non-terminating (loop-
ing) use may be used in the branch, however the
last unit in line must be terminated with 75
ohms.
