Figure 28 below illustrates a typical four-channel setup using the IC-1 Control Center. Each
interpreter monitors the floor signal independently via the “Floor In” connection. To transmit the
interpreted message to the listener, the interpreter selects the “Norm” push button on the IC-1 to
send their mic signal to the MOD 232 Modulator. To transmit the floor signal directly to the listener,
the interpreter selects the “Off” push button on the IC-1. Listeners use four-channel wireless IR
receivers (RX12-4) to select the language they understand. Additional instructions are included with
the IC-1.
