General Description
The IC-100 allows the assignment of any two of six
input lines to any one of twelve two channel outputs.
In addition, the six input lines are available as a loop
through output. All input are protected against
transients and power crosses.
IC-100 Product Features
• Input and output connections are compatible with
BTR-1 Wireless Intercom.
• Non-shorting rotary switches allow reconfiguration
without channel cross-connection.
• An active power monitor indicates the presence of
power on all input lines with minimal loading.
• D sub to XLR breakout on rear panel.
Inputs
There are two ways to connect input lines to the
IC-100:
1. Feed the lines into the 15 pin D sub connector on
the rear panel marked I/C IN. The pin assignments
are shown in Table 1.
2. Connect a patch cable between I/C IN and
EXTERNAL LINES OUTPUT on the rear panel
and feed the lines into the six XLR connectors
marked EXTERNAL LINES INPUT.

Loop Through Outputs
Loop through connections may be made in one of three
ways.
1. Connect to the three pin XLR connectors on the
front panel. Each line has two connectors available.
2. Connect to the 15 pin D sub connector on the rear
panel marked I/C OUT. The pin assignments are
the same as for the I/C IN connector.
3. Connect a patch cable between I/C OUT and
POWER SUPPLY OUTPUT and connect to the six
three pin XLR connectors marked POWER
SUPPLY INPUTS.
