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.
• The ICS-22 is a
two-channel speaker
panel.
• The panel must be
powered locally.
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.
• Users can install the
panel in Clear-Com’s
DT-Box.
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.

OPERATION
Normal operation of the ICS-22 speaker panel only requires the front
panel controls. For intercom operation, set the intercom level control to
the desired level and press the talk button when talking. If a headset or
handset is used, set the sidetone control for each channel for the
desired amount of sidetone in the earphone. If the PT-4 hand-held,
push-to-talk microphone is used, or if the panel microphone is used,
set the sidetone controls for minimum feed-through to the speaker to
prevent acoustic feedback.
ECS System Configuration for ICS-22 Panels
The Eclipse Configuration System (ECS) software does not directly
support the ICS-22 speaker panel. In order to configure an ICS-22
panel the port is configured to drive an ICS-1008 panel with 14 keys (7
pairs of buttons). The two ICS-22 selectors are mapped onto the
ICS-1008 keys starting from the left. Only the leftmost two pairs of
keys on the ICS-1008 can be used to program the ICS-22; any other
keys on the ICS-1008 will have no effect.
There must be a corresponding listen key on the top row to the talk key
on the bottom row of the ICS-1008 configuration for the ICS-22 panel
to work correctly. If a talk key only is configured on the ICS-1008 in
ECS the Talk key on the ICS-22 will not latch.
It should be noted that the panel signalling and control protocol used
by the Eclipse matrix differs from the Matrix Plus 3. As a result the
operation of these panels with an Eclipse matrix may be slightly
different to their operation with a Matrix Plus 3.

Panel-Mic Connector
• To install a GM-9 or
GM-18 microphone
there are four steps.
Clear-Com recommends that the GM-9 (9-in. long) and GM-18 (18-in.
long) plug-in panel microphones be used with the ICS-22. Both are the
electret type. The 1/4-in. phone jack on the microphone mates with the
panel-mic receptacle on the ICS-22’s front panel.
To install a GM-9 or GM-18 microphone:
1. Remove the plastic plug from the jack, if present.
2. If a set screw is present in the microphone-mounting flange, check
and unscrew it to make sure it is clear of the threads in the bushing.
3. Screw the microphone into the bushing and tighten.
4. Optional: Replace the set screw supplied with the gooseneck
microphone on top of the microphone-mounting flange and turn it
clockwise to lock the microphone in place.
VOX Control
• The VOX control is
located to the right of
the panel microphone
connector and is
recessed slightly into
the front panel.
When the panel microphone is selected on the ICS-22, the VOX
control should be adjusted for proper operation. This control is located
to the right of the panel microphone connector and is recessed slightly
into the front panel. Use a narrow, flat-bladed screwdriver such as a
“greenie” or “tweaker” for this adjustment. When the adjustment is
correctly set, the talk lamp will be red when speaking into the panel
microphone and will be green when hearing audio from the speaker.
Turning the control clockwise makes the ICS-22 more sensitive. The
VOX feature can be disabled by turning the VOX control fully
counterclockwise.

Program-Input Connector (4)
A three-terminal, plug-on connector provides the program input to the
panel. Program is fed to the headset and speaker. The level to the
speaker or headset is controlled by the program-level control. The
program-input connector accepts a balanced or unbalanced line-level
audio signal from -20 dBu to +10 dBu. If this input is connected to the
stage announce (SA) output of a main panel it can be used as a paging
input. Since the level of this input is independently adjustable from the
intercom audio volume, it can be used to override the intercom audio.

• The panel can obtain
power from three
different sources.
Power Connection (5)
The panel requires local power, which can come from various sources,
including:
16-VAC Doorbell Transformer
• Note: Both 10-VAC
and 16-VAC doorbell
transformers are
commonly available
at hardware stores,
but only the 16-VAC
transformers are
suitable in this
case.The panel can
obtain power from
three different
sources.
A doorbell transformer can be attached to a separate box containing
the power-line connection and the low-voltage, 16-VAC can be routed
to the connector on the EB7-4W circuit board. This connection is
especially useful if the headset or speaker panel is installed in a wall.
14-VAC Wall-Mounted Power Supply
A Clear-Com wall-mounted power supply (part number 400008) can
be used for powering the panel from 120 VAC. (Use part number
400011 for 220 VAC power.) This connection is a better choice if the
headset or speaker is mounted in a desktop box, such as a Clear-Com
DT-Box, which is not located on a wall.
24- to 28-VDC Source
The headset or speaker panel can be powered from a DC source, such
as batteries.
To connect the selected power supply:
1. Connect the two wires from the power source to the two-position,
plug-on terminal strip.
2. Plug this connector onto the circuit board as shown in Figure 1-2 on
page 1-8.
