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.
