The conference system is a plug-and-play system designed for use in small and
medium-sized conferences and events. The call stations are connected to each
other as well as to the control centre via system cables. The system cables
handle the transmission of the digital voice and status information as well as
the power supply of the call stations. The control centre has a built-in power
supply that can power up to 32 call stations.
Connection options
Up to 16 call stations can be connected in 2 lines to the control centre
Call station setup
This is how to connect the call stations to the control centre and to each other:
- Connect the [IN] interface of the first call station (33) to the [CONFERENCE INPUT] inter‐ face of the control centre. To do so, use a LAN cable.
- Connect the [LINK] interface of the first call station (32) to the [IN] interface of a further call station. To do so, use a LAN cable.
- Repeat step 2 until you have connected the desired number of call stations to a line.
You can connect a maximum of 2 lines, each with 16 call stations, to the control centre.
Microphone installation
This is how to attach the microphone to the call station:
-
Plug the microphone on the microphone jack [23].

Plug and pin assignments
Introduction
This chapter will help you select the right cables and plugs to connect your
valuable equip‐ ment in such a way that a perfect sound experience is ensured.
Please note these advices, because especially in ‘Sound & Light’ caution is
indicated: Even if a plug fits into the socket, an incorrect connection may
result in a destroyed power amp, a short circuit or ‘just’ in poor
transmission quality!
Balanced and unbalanced trans‐ mission
Unbalanced transmission is mainly used in semi-professional environment and in
hifi use.
Instrument cables with two conductors (one core plus shielding) are typical
representatives of the unbalanced transmission. One conductor is ground and
shielding while the signal is trans‐ mitted through the core.
Unbalanced transmission is susceptible to electromagnetic interference,
especially at low levels, such as microphone signals and when using long
cables.
In a professional environment, therefore, the balanced transmission is
preferred, because this enables an undisturbed transmission of signals over
long distances. In addition to the conduc‐ tors ‘Ground’ and ‘Signal’, in a
balanced transmission a second core is added. This also transfers the signal,
but phase-shifted by 180°.
Since the interference affects both cores equally, by subtracting the phase-
shifted signals, the interfering signal is completely neutralized. The result
is a pure signal without any noise inter‐ ference.
