Setting up the SDC 8200 system

Connecting additional equipment

Via the two audio inputs AUX IN 1 and AUX IN 2 of the central unit, you can connect microphones with suitable preamplifiers or you can feed audio signals from additional audio equipment to the conference system.

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

The output signal of the floor channel is available at the audio output AUX OUT 1. Via the five audio outputs AUX OUT 2 to AUX OUT 6, you can output any desired channel (floor channel or interpretation channels).

Via the audio outputs, you can:

yconnect a PA system via which the floor channel or an interpretation channel can be transmitted to e.g. the foyer or another room,

ytransmit the audio signal of the floor channel or an interpretation chan- nel as “original soundtrack” to a broadcasting station,

yconnect 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. With the SDC 8200 CU central unit, guests or participants can choose between the floor channel and up to 28 interpretation channels. With the SDC 8200 CU-M central unit, guests or participants can choose between the floor channel and up to four interpretation channels.

Optionally, you can connect an SDC 8200 AO analog output unit to the cen- tral unit. The analog output unit features nine XLR-3M audio outputs via which you can output the floor channel and up to eight additional interpre- tation 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, wire- less 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 107 and “Adjusting the input level of an audio input” on page 107).

You can turn the audio inputs on and off via the central unit’s operating menu (see “Turning on/off the audio inputs or outputs” on page 106).

Setting up 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 sys-
