3 Applications
The CS-1 system is used for technical support
of conferences and discussion events with up to
50 microphone stations. Additional audio con-
nections on the controller CS-1CU make it easy
to integrate other devices (such as recorders,
amplifiers, wireless microphone systems, equal-
izers, telecommunications).
Each microphone station (CS-1DU and
CS-1CH) is equipped with a high-quality
microphone capsule, a speaker and two head-
phone jacks with volume control. The micro-
phone stations for chairpersons (CS-1CH) have
a priority button, allowing the chairperson to
interrupt the discussions of other delegates for
their own messages.
Various discussion modes (e. g. a defined
number of delegates talking at the same time
or a talking time with automatic limit), an indi-
cation of date and time, a separate stopwatch
feature, a key lock feature for the controller
and a test feature for all microphone stations
connected make the system extremely versatile.
If more than 50 microphone stations are
required, the CS-1EXM and CS-1EXS devices,
available as accessories, can be used to combine
two or three conference systems to create a
system that may contain up to 150 microphone
stations.
4 Connections
Always switch off the devices before making or
changing any connections!
4.1 Microphone stations
For connecting the microphone stations, the
two jacks "Trunk in /out" (19) are provided on
the controller. Each of these two jacks can be
used to connect a chain of up to 25 microphone
stations of type CS-1CH and /or CS-1DU.
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 micro-
phone station to the jack (28) on the rear of
the first microphone station (or to the other
jack "Trunk in /out" on the controller).
3) Proceed in the same way to connect further
microphone stations. CS-1CH and CS-1DU
