CLEAR-COM INSTRUCTION MANUAL
INTRODUCTION
1 . 1 GENERAL
The Clear-Com system is a closed circuit intercommunication system
designed for
clear- two-way communication in high noise environments.
Low impedance lines (200 ohms) and specially designed circuitry make the
system
virtually immune to RF and dimmer noise. The basic system consists
of a
main station and from one to 40 remote stations, joined by inter-
connecting cable. Main stations are available in portable cases (single
channel
CS-100 and dual-channel CS-200), as well as rack-mountable enclosures
(CS-100K and CS-200K). There are several interchangeable remote stations:
the RS-100A "belt pack", the KB-100 liKing Biscuit" mic/speaker unit, the
MR-102 wall-mount unit, the KB-lll wall mount unit with speaker, and the
KB-lllP portable
remote unit with speaker. The master gain control, located
on the main station rear panel, allows the operator to set the overall gain
in accordance with the
number of remote stations being used.
All remote stations, except the MR-102, have adjustable side tone
which enables the user to vary the amount of his or her own voice in the
headset, handset or speaker
for maximum intelligibility with minimum chance
of feedback.
All remote stations have their own volume control for ad-
justing the level in the earpiece (s), call switches and call lights for
signaling
from other stations.
Clear-Com is a distributed amplifier system, with each remote station
housing its own mic preamplifier and headset power amplifier (+20dBm max
output). The main station supplies 28V dc necessary for operating all
circuits, and power is carried to remote stations via the same interconnecting
cable
which carries the audio signals. The main stations also have an
auxiliary, line-level input with its own volume control which allows mixing
of an external program with the intercom line. This is useful for program
monitoring.
A power-supply only
main station is available, the model PS-3000.
Standard microphone cables (XLR-3 type connectors) are used for inter-
connection in most cases; the WP-l and WP-2 wall-mount connector plates
may be used in some permanent installations. Interconnect cables, and a
4-way splitter (the Quadropuss) are available from Clear-Com.
