Clear-Com Encore IF4W4 Quick Start Manual

Quick
Start
Guide
IF4W4 is a 4-channel 4-wire 1RU interface that enables an Encore intercom system to connect to 4-wire communication systems,
such as TV cameras, 2-way radios and fiber circuits. This Quick Start Guide provides basic installation and operating instructions,
and a quick reference to system topologies and cables.
Note: For more detailed information about the IF4W4 Interface, see the IF4W4 4-Wire Interface User Guide, and the
Encore System Installation Guide.

Before installing

Review the cable specifications for the venue or application before installing.
•
Unpack the unit and inspect for any damage that may have occurred in shipping.
•
• Locate the device away from other equipment that generates excessive amounts of heat.

Powering the Interface

Interfaces require adequate power from the partyline system's power source, normally a Main Station or Power Supply, to
guarantee optimal system performance. Power reserves are shared between the system's user stations and channels and are
drawn dynamically. Power consumption depends on system levels.
Note: System power requirements can easily be estimated using the Clear-Com Power Calculator,

beyond a single power source.

Installing the Interface

1. Connect a shielded cable from one channel
of the Main Station (C) to an XLR-3 port on
the IF4W4 Interface. (A).
2. Verify that the 2-wire partyline intercom system
is properly terminated.
(G)
3. Set the Link switches
how many 4-wire systems are on the partyline.
4. Connect the IF4W4 Interface terminal block connector
to the 4-wire device. (B).

Operating the Interface

1. Set all input and output level controls
to the center position (12 o'clock).
2. Listen to the intercom and adjust the
input / receive levels (F)
interfaced device with the level of talkers on the
intercom stations.
3. Listen to the interfaced device and adjust the output / transmit
levels (F) from each interface for optimal listen levels
on the interfaced device.
For each channel, adjust the null control as follows:
4.
a. Connect an earphone or a 4-pin XLR headset to the Null Monitor connector
Push the appropriate test null button. (E).
b.
c. Adjust the R, L and C null controls
d. Repeat steps 2-4 to make fine adjustments.
