[. . . ] To interconnect the central units: At the first central unit, connect the black RJ 45 plug of the system cable to the MASTER OUT socket ¸. If the SLAVE IN socket ¹ of a central unit is not connected, this central unit automatically becomes the "master". Connect the grey RJ 45 plug of the system cable connected to the "master" to the SLAVE IN socket ¹ of the second central unit. If the SLAVE IN socket ¹ of a central unit is connected, this central unit automatically becomes a "slave". To connect additional "slaves", connect the SLAVE OUT socket of the first "slave" to the SLAVE IN socket of the following "slave", and so on. · ³ ¹ ¸ 48 Setting up the SDC 8000 system Note!The entire conference and interpretation system is configured, managed and controlled exclusively via the "master" central unit. All operating controls on the "slaves" are locked. This is indicated by a "key" symbol ( ) in the lower right corner of the display. Turning the central units on and off When turning on a conference and interpretation system with several central units, it is important that the central units are turned on in the correct order. First turn on the "master" central unit. Then turn on the "slave" central units in the order in which they are connected to the "master". To turn a central unit on: Set the POWER switch to position "I". The consoles which are powered via this central unit are ready for operation as soon as they are initialized. The start display is shown on the LC display of this central unit. >Volume = P1 P2 P3 P4 P5 P6 To turn a central unit off: Set the POWER switch to position "0". All consoles which were powered via this central unit are also turned off. It is, however, possible to simultaneously turn on interconnected central units via a switchable multiple socket. 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 two audio outputs AUX OUT 1 and AUX OUT 2. Via the three audio outputs AUX OUT 3 to 5, you can output any desired channel (floor channel or interpretation channels). Via the audio outputs, you can: connect a PA system via which the floor channel or an interpretation channel can be transmitted to e. g. the foyer or another room, 49 Setting up the SDC 8000 system transmit the audio signal of the floor channel or an interpretation channel as "original soundtrack" to a broadcasting station, 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.
