3 Applications

The CS-50 system is used for technical support of
conferences and discussion meetings with up to 50
microphone stations . Via additional audio connections
on the controller CS-50CU, further units (e . g . record-
ers, amplifiers, wireless microphone systems, equal-
izers, telecommunication) will easily be integrated .
Each microphone station (CS-50DU and CS-
50CH) is equipped with a high-quality microphone
cartridge, a speaker and two headphone jacks with
a volume control . CS-50CH, the microphone stations
for chair persons, are also provided with a priority
button which will allow chairpersons to interrupt
other delegates for their own announcements .
Various discussion modes (e . g . a defined num-
ber of delegates talking at the same time or a talking
time with automatic limit), an indication of date
and time, a separate stopwatch feature, a key lock
feature for the controller and a test feature for all
microphone stations connected will allow versatile
applications of the system .

4 Making Connections

Always switch off the units prior to making or chang-
ing any connections!

4.1 Microphone stations

For connecting the microphone stations, the two
jacks "Trunk in /out" (19) are provided on the con-
troller . Each of the two jacks will allow connection
of a chain of up to 25 microphone stations of the
type CS-50CH and /or CS-50DU .
1) Connect the plug (29) of the first microphone
station to one of the jacks "Trunk in /out" (19) .
2) Connect the plug (29) of the second microphone
station to the jack (28) on the rear side of the first
microphone station (or to the other jack "Trunk
in /out" on the controller) .
3) Connect further microphone stations in the same
way . The CS-50CH and CS-50DU units may be
connected in any order . The number of micro-
phone stations connected to the two jacks on
the controller may also be different .

4.2 Additional microphone

It will be possible to connect an additional micro-
phone or the receiver of a wireless microphone via
the jack "Microphone" (20) . For microphones requir-
ing a phantom power supply, a voltage of 12 V (⎓) is
present at this jack . Therefore, do not connect any
microphones or wireless 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 re-
corder to the RCA jacks "Recorder out" (15) . The
signal level at these jacks will be independent of the
speaker volume 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) channel respectively of a stereo recorder;
however, signal processing in the conference system
will be monophonic .

4.4 Signal source with line level

A mono signal source with line level (e . g . the out-
put 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
connected 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
"Telephone" (13) . This telephone coupler will electri-
cally 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 compres-
sor for dynamic limiting) into the signal path of the
conference system, connect the input of the unit to
the jack "Insertion out" (14) and its output to the
jack "Insertion in" .
Set the switch (12) to position "I" so that the
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 provided 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
corresponding 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) .
