y transmit the audio signal of the floor channel or an interpretation channel as “original soundtrack” to a broadcasting station,

y connect an infrared language distribution system to the central unit, allowing guests or participants who don’t have their own conference console to follow the conference via infrared headphones. These guests or participants can choose between the floor channel and up to 28 interpretation channels.

Optionally, you can connect an SDC 8000 AO analog output unit to the central unit. The analog output unit features nine XLR-3M audio outputs via which you can output the floor channel and up to eight additional interpretation channels and to which you can connect external equipment such as a recording unit, etc.

Connecting external audio sources

You can connect external audio sources such as wired microphones, wireless microphone systems, the audio output of a video recorder, a CD player, etc. to the central unit. The audio sources to be connected must deliver a balanced mono signal at the XLR-3F sockets.

The external audio signals are fed to the floor channel which is output via the consoles’ built-in loudspeakers.

To connect an audio source:

￿Use an audio cable with XLR-3 connectors to connect the audio source

to one of the XLR-3F sockets (AUX IN 1 or AUX IN 2 ) of the central unit.

￿If necessary, adapt the input sensitivity and the volume of the audio input via the central unit’s operating menu (see “Adjusting the input sensitivity of an audio input” on page 96 and “Adjusting the input level of an audio input” on page 96).

You can turn the audio inputs on and off via the central unit’s operating menu (see “Turning the audio inputs or outputs on and off” on page 95).

Carrying out remote conferences

Instead of connecting an external audio source to the audio input of your conference system, you can connect the audio output of a conference system installed in a separate room to carry out a remote conference. The participants of both conferences can then participate in a common conference.

To connect two conference systems installed in separate rooms, you require two XLR cables with two XLR-3 connectors respectively:

￿ Connect the audio input AUX IN 1	of the first central unit to the audio
output AUX OUT 1 of the secend central unit.
￿ Connect the audio input AUX IN 1	of the secend central unit to the

audio output AUX OUT 1 of the first central unit.

￿From the central unit’s operating menu, choose “Dist. Conf. = ON” to prevent echo (see “Configuring the audio outputs for remote conferencing” on page 95).
