OPERATION
DESCRIPTION
The Clear-Com ICS-22 is a two-channel speaker panel designed for
use in theatres, live performances, industrial environments, and small
television facilities. It features excellent speech intelligibility, even in
high noise levels, and can be customized through its programmable
options.
In addition, the ICS-22 contains a jack for an optional Clear-Com
gooseneck panel microphone and a close-in, voice-operated circuit
(VOX). This circuit allows automatic, alternate dipping of the panel
microphone and the speaker in response to conversation.
Selectable talking and/or listening allows the operator to communicate
on two talk/listen paths. The dual-action talk button operates in
electronic momentary or latching mode. Monitoring can be done
through the headset, the integral speaker, or both simultaneously. The
ICS-22 offers both visible and audible call signaling to attract the
attention of operators.
A balanced program input allows the monitoring of external audio
using the headset or speaker. This program input can also be used as
a paging function.
The ICS-22 speaker panel accepts dynamic headsets, such as the
Clear-Com PL-Pro
™
Series HS-6 Telephone Handset, or PT-4
Push-to-Talk Hand Microphone. A sidetone control allows the operator
to vary the level of his voice heard through the headset and speaker.
The integral speaker can be turned on or off by a convenient
front-panel switch. An automatic speaker dipping circuit will lower the
level of the speaker whenever the talk button is activated. The
ICS-22’s close-in VOX dips the speaker or gooseneck microphone
automatically as the panel is used. These features help minimize
acoustical feedback.
The ICS-22 will need to be powered locally. In permanent wall
installations, a 16-VAC doorbell transformer will provide a convenient
source of power. In DT-Box installations, a 14- to 18-VAC
wall-mounted transformer will suffice. The connections to this
transformer are made to the circuit board’s two-terminal, plug-on
connector.
The unit mounts either in a standard USA four-gang electrical outlet
box or in an optional Clear-Com DT-Box. The extra thick front panel
and compact, surface-mounted circuitry results in a reduced size and
lighter weight package that maintains Clear-Com ruggedness.
