SWITCHERS
1. INTRODUCTION
This manual provides information on installation and opera-
tion for the
and
Series
Follow-video Switchers. These units should only be
installed by qualified technicians using approved materials
and wiring practices in accordance with federal, state, and
local electrical codes. Read these instructions thoroughly
before installation.
The
and
Series
Video Switchers are microprocessor-controlled units that
allow audio devices associated with video systems to be
switched at the same time as the video. Both models
provide passive relay-based audio switching.
This series of relay switchers is compatible with Matrix
and Matrix
switchers and with
VPS 1344, and VPS328 digital control systems. In a typical
application, the audio signal from an intercom microphone
associated with a video
can be switched to a speaker
at the guard station at the same time the video is switched to
the guards monitor.
Two basic models of the relay switcher are available:
model
32 balanced monaural inputs,
while model
provides 32 balanced stereo inputs.
Refer to Figure 1 and Figure 2. Each input/ output of the
has two relay contacts. The
sup-
ports stereophonic audio systems or other systems re-
quiring four contacts to be active at each switch.
Input/output proportions are configured by setting inter-
nal jumpers and include the following combinations:
32 inputs, 1 output, mono-balanced;
16 inputs, 2 outputs, mono-balanced;
8 inputs, 4 outputs, mono-balanced;
32 inputs, 1 output, stereo-balanced;
16 inputs, 2 outputs, stereo-balanced;
8 inputs, 4 outputs, stereo-balanced.
Multiple relay switchers may be cascaded, enabling them
to be used with switching systems of more than 256
cameras.
Relay connections are made via convenient
detachable screw terminal blocks.
Both inputs and outputs are balanced to provide maxi-
mum hum and noise rejection. Unit specifications have
been designed for a high-fidelity range and include:
crosstalk: better than -70
at 20
frequency response: flat within 0.3
from
10 Hz to 20
hum and noise: typically better than -60
This precise conformity to the highest standards makes
the V
and the
relay switcher suitable
for virtually any audio application.
Any Vicon Nova digital control can supply the
or the
with the information necessary to relay
the signal from a source to an output. In the standard
configuration, an operator selects a desired source/output
combination and enters the assigned numbers into the
keypad.
WARNING: TO PREVENT RISK OF FIRE OR ELECTRIC SHOCK, DO NOT EXPOSE THIS UNIT TO RAIN OR MOISTURE.
