DANGER!
Electric shock caused by short-circuit
Always use proper ready-made insulated mains cabling (power cord) with a pro‐
tective contact plug. Do not modify the mains cable or the plug. Failure to do so
could result in electric shock/death or re. If in doubt, seek advice from a regis‐
tered electrician.
CAUTION!
Possible hearing damage
The use of headphones or earphones at high volume and for an extended period
of time may result in permanent hearing impairment.
Set the volume of your audio device to a medium value and do not use the head‐
phones or earphones for more than about an hour a day.

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.

8 Plug and connection assignment
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 ts into the socket, an incorrect connection may result in a destroyed power amp, a short
circuit or ‘just’ in poor transmission quality!
Unbalanced transmission is mainly used in semi-professional environment and in hi 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°.
Introduction
Balanced and unbalanced trans‐
mission

Page 37
Since the interference aects 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.
