Structuring and controlling the
conference system
Structuring the conference system
The ADN conference system is suitable for conferences with up to 400 conference
units. For safe operation of the conference system, make sure that all conference
units are supplied with a voltage of at least 35 V! The voltage supplied depends on
the number of connected conference units and on the cable lengths. The standard
cable length between the central unit or power supply and the first conference unit
is 80 m max. and the standard cable length between the individual conference
units is 2 to 5 m.
If these cable lengths are observed, safe operation of conference systems with the
following number of conference units is ensured:
• small conference systems comprising only an ADN CU1 central unit
– 30-40 conference units connected in simple strings
• large conference systems comprising an ADN CU1 central unit and a max. of
15 ADN PS power supplies
– max. 400 conference units connected in simple strings or in ring topology
per ADN PS power supply
– 60-70 conference units connected in simple strings
– 30-40 conference units connected in ring topology
If cable lengths are shorter, it might be that more conference units can be used.
ADN D1 delegate units and ADN C1 chairperson units can be combined in an arbi-
trary order. The number of chairperson units, however, is limited to 10 max. per
conference system. All components of the conference system are interconnected
using SDC CBL RJ-45 system cables.
Small conference system with simple cabling
For small conference systems with approx. 30-40 conference units, you require one
ADN CU1 central unit for controlling the conference. The conference units are interconnected in two cable strings which are directly connected to the central unit.

Large conference system with redundant ring topology
The redundant ring topology ensures that, should one conference unit or system
cable fail or be manipulated, all other conference units of the cable ring will
continue to function reliably.
For setting up a large conference system with redundant ring topology, you require
one ADN CU1 central unit for controlling the conference and additional ADN PS
power supplies for powering the conference units. The conference units are interconnected in rings and two rings can be connected to each ADN PS power supply.
8 | ADN CU1
Calculating the voltage supply of the conference units
The “ADN Cable Calculator” software allows you to calculate the voltage supply on
the individual sections of a cable string or cable ring and to plan the structure of
the conference system. The software is available from your Sennheiser partner or
from the “Product Downloads” area on the product page at www.sennheiser.com.
For further information on the installation and use of the “ADN Cable Calculator”
software, refer to the help section of the “ADN Cable Calculator” software and to
the detailed instruction manual “ADN Conference System”.
Configuring and controlling the conference system
For configuring the conference system, you can either use the operating menu of
the central unit or the “Conference Manager” software. The software also allows
you to control conferences via a graphical interface.

Setting the volume of the conference units’ built-in
loudspeakers
You can set the volume of the conference units’ built-in loudspeakers via the jog
dial on the central unit. The standard display displays the current volume
setting H.
CAUTION
Danger of hearing damage due to loud hissing!
When the floor channel volume is set to a high level or when several
participants speak simultaneously, feedback (loud hissing noise) can
occur. This can cause hearing damage.
왘 Reduce the floor channel volume (see below).
왘 Activate the “Feedback Suppression” function to be able to
increase the volume before feedback can occur (see page 17).
왘 Make sure that the “Audio Gain Reduction” function is activated
(see page 17). This function reduces the gain per active microphone by the selected level and thus prevents feedback noise.
왘 Increase the distance between the individual conference units to
at least 50 cm.
왘 Turn the jog dial
– to the right to increase the volume or
– to the left to reduce the volume.
Use the “Feedback Suppression” function to be able to increase the floor
channel volume by up to 5 dB without feedback occurring (see page 17).
