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.
