This configuration has two target languages, one interpreter booth, and one interpreter console.

Both interpreters monitor the floor signal via the FLOOR IN connection. Interpreter 1 turns her microphone ON and chooses NORM to send her voice to Transmitter 1 (TX1) via the NORM OUT connection. When the first interpreter is finished, Interpreter 2 moves the microphone switch to turn her microphone ON and chooses the KEY button to send her microphone signal to Transmitter 2 (TX2) via the KEY OUT connection.

This configuration has three target languages, two interpreter booths, and two interpreter consoles. 
This set-up can be used in two ways:

Situation 1 allows 4 interpreters in two booths to work three languages when the floor language doesn’t change and both interpreters understand the floor language, or

Situation 2 allows 4 interpreters in two booths to work three languages when the floor language does change and the interpreters in one booth do not understand the floor language.

Each interpreter operates independently. Both monitor the floor signal via the FLOOR IN connection. A distribution amplifier is needed to provide the floor signal to each IC-1. The NORM OUT jack of each IC-1 is connected to a transmitter (TX2 and TX3) to provide language 2 and language 3.  The KEY OUT connection from each IC-1 is connected to a mixer to allow either interpreter to provide a relay signal. A distribution amplifier sends the relay signal to the RELAY IN connection of each IC-2 and to a third transmitter (TX1).

Each interpreter selects the NORM button to send her microphone signal via the NORM OUT connection to the transmitter for their language. When both interpreters are using the NORM mode, the floor signal feeds through J2 (if it is closed) to the KEY OUT jacks of both IC-1s. The signal then feeds to the TX1 through the distribution amplifier. This would allow listeners to hear the floor signal (language 1) on channel 2 and language 3 on channel 3.

One of the interpreters acts as the “key language” source. The interpreters can take turns providing the key language if they wish. If Interpreter 1 is going to provide the relay signal, he or she selects the KEY mode while interpreter 2 selects the RELAY mode.

Now Interpreter 1 will hear the floor signal (language 1) and their microphone will be connected to the KEY OUT jack, which feeds the RELAY IN jack of the second interpreter’s console and also Transmitter TX3 through the mixer and distribution amplifiers. If J1 is closed on Interpreter 1’s console, the floor signal will feed-thru the NORM OUT connection to the Transmitter TX2.

With Interpreter 2 in the RELAY mode, they will be listening to Interpreter 1 via the RELAY IN connection. their microphone will be connected to the NORM OUT jack to Transmitter TX3. J2 should be open on the Interpreter 2’s console. J1 may be closed.  If Interpreter 2 is going to provide the Relay signal, he or she selects the KEY mode on their console and interpreter 1 selects the RELAY mode on their console.

This configuration has four target languages, four interpreter booths, four interpreter consoles, eight interpreters, and relay.

Each interpreter booth operates independently. All monitor the floor signal via the FLOOR IN connection.

A distribution amplifier is needed to provide the floor signal to each IC-1. Each interpreter booth selects the NORM button to send a microphone signal via the NORM OUT connection to the Transmitter for their language.

The “Pivot” booth provides the relay signal via the NORM OUT connection to a second distribution amplifier.

The distribution amplifier sends the relay signal to the English transmitter and to each of the other interpreter booths via the RELAY IN connection on their IC-1.

When the other three interpreter booths select NORM, they are listening to the original floor signal and their voice is being sent to their transmitter. When they select RELAY, they are listening to the pivot interpreter booth (usually speaking English) and their voice is sent to their transmitter.

With J1 closed on all IC-1’s, the floor signal will feed thru the NORM OUT connection to the Transmitter when the interpreter selects OFF. This allows the listeners to hear the floor language directly when it is their native language.
