4.2 Additional microphone
GB
It will be possible to connect an additional microphone
or the receiver of a wireless microphone via the jack
"Microphone" (20). For microphones requiring a phantom
power supply, a voltage of 12 V is present at this jack.
Therefore, do not connect any microphones or wire-
less receivers with unbalanced output signal to this
jack; otherwise they may be damaged.
4.3 Recorder
To record a discussion, connect the input of a recorder
to the RCA jacks "Recorder out" (15). The signal level
at these jacks will be independent of the speaker vol-
ume adjusted.
To reproduce a recording, connect the output of the
recorder to the RCA jacks "Recorder in". The jacks are
available for the left (L) channel and the right (R) chan-
nel respectively of a stereo recorder; however, signal
processing in the conference system will be mono-
phonic.
4.4 Signal source with line level
A mono signal source with line level (e. g. the output of
a mixer) can be connected to the RCA jack "Line in"
(16).
If only a stereo signal source is available and the
input "Recorder in" is not used, the source can be con-
nected to this input.
4.5 Amplifier system
To reproduce the discussion via an amplifier system,
connect the input of the amplifier or mixer to the jack
"Line out" (16).
4.6 Telephone coupler
To allow participation in the discussion by phone, a
telephone coupler can be connected to the jacks "Tele-
phone" (13). This telephone coupler will electrically
adapt the telephone network to the conference system
as required.
Caution: Never try to connect a telephone line directly
to the conference system!
4.7 Inserting external signal processing
To insert an additional unit for signal processing (e. g.
an equalizer for matching the sound or a compressor
for dynamic limiting) into the signal path of the confer-
ence system, connect the input of the unit to the jack
"Insertion out" (14) and its output to the jack "Insertion
in".
Set the switch
external sound processing will take effect.
4.8 Headphones
As an alternative to the speakers, headphones can be
used for hearing. For this purpose, the controller is pro-
12
(12) to position "I" so that the
vided with a jack (2), the microphone stations are
equipped with a jack (24) on the left and on the right
each. Once a plug is connected to a jack, the corre-
sponding speaker will be switched off.
4.9 Power supply
Finally connect the mains cable provided to the mains
jack (10) first, then connect it to a mains socket
(230 V~/50 Hz).
5 Operation
Note: If no unit for external sound processing is con-
nected to the jacks "Insertion" (14) or if a unit con-
nected to these jacks is not used, set the switch
to position "O".
Set the volume control
the controller with the POWER switch
play (5) will show the last operating mode selected and
also the date (format: year - month - day) and the time
(format: hour : minute : second).

(6) or
lowing operating modes:
"Over Ride Mode"
A delegate will switch on his/ her microphone by
shortly pressing the talk button (27). The LED (23)
at this microphone station and the ring (22) of this
microphone will light up as long as the microphone
is switched on. To switch it off, press the button
once again.
Once another delegate switches on his/ her
microphone, the microphone of the delegate talking
before will be switched off automatically.
Switching-off will not affect the microphone of a
chairperson at a microphone station CS-50CH. It
will be possible to switch it on/off at the same time
as the other microphone stations.
"Chairman Only"
Only a chairperson at a microphone station CS-
50CH will be able to switch on/off his/ her micro-
phone via the talk button (27); the microphones of
the delegates will remain switched off.
"Open Mode"
A defined number of delegates will be able to talk at
the same time. If the maximum number of micro-
phones is switched on, it will not be possible to add
another microphone. A delegate requesting to
speak will have to wait until one of the delegates
talking before has switched off his/ her microphone.
This limitation will not apply to a chairperson at a
microphone station CS-50CH; he/she will be able to
(4) to "1" first, then switch on
