conference system
Structuring a wired conference system
Basic requirements for a conference system comprising wired conference units
For safe operation of the conference system, make sure that all wired 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 50 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 arbitrary order. The number of chairperson units, however, is limited to 10 max. per
conference system. All wired components of the conference system are interconnected using SDC CBL RJ-45 system cables.
Calculating the voltage supply of the conference units
The “ADN Cable Calculator” software allows you to calculate the voltage supply of
the wired conference units on the individual sections of a cable string or cable ring
and to plan the structure of the conference system. The software is included on the
DVD-ROM (supplied with the ADN CU1) or is available from your Sennheiser partner or from the “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 ADN system manual.

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.

Setting up a wireless conference system
Basic requirements for a conference system comprising wireless conference units
The ADN-W C1 and ADN-W D1 wireless conference units connect wirelessly to the
ADN-W AM antenna module, which is connected to the ADN CU1 central unit via
system cable. The ADN-W AM antenna module can manage up to 75 wireless conference units. The battery-powered wireless conference units are easy to use and
offer a high degree of flexibility. If the power supplied to the antenna module via
the system cable is not sufficient, you have to power the antenna module using the
NT 12-50C power supply.
Wireless conference system
For setting up a wireless conference system, you require one ADN CU1 central unit
for controlling the conference and at least one ADN-W AM antenna module for
operating the wireless conference units (range approx. 30 m).

the central unit or the “Conference Manager” software. However, the full functionality of a wireless conference system can only be configured using the “Conference
Manager” software. The software also allows you to control and monitor conferences via a graphical interface.
The “Conference Manager” software can be run in two different ways:
1. As a program on the central unit’s built-in PC
You have to connect a screen, keyboard, and mouse to the central unit (see
page 17).
2. As a program on a Windows PC
You have to install the “Conference Manager” software on the PC and integrate
the PC together with the central unit in a network (see page 17).
For information on the installation and use of the “ADN Cable Calculator”
software, refer to the ADN system manual.
Input and output of audio signals
Via XLR sockets, you can feed audio signals to the floor channel or output the floor
channel.
For recording a conference on a USB mass storage device, you can use the recording
function of the ADN CU1 central unit, which saves the floor channel and all channels
of the conference units as audio files in wav format.
Integration into a media control system
The ADN conference system can be completely integrated into a media control system. You can monitor and control all functions of the conference system via the
programmable commands of your media control system. For information on the
integration into a media control system, refer to the ADN system manual.

Setting up the conference system
CAUTION
Product damage due to an unsuitable power supply!
If you connect standard network devices with RJ45 plugs (e.g. switches or network
cards) to the connection sockets PORT I , PORT II, DATA PS and / , the net-
work devices can be damaged due to an unsuitable power supply.
왘 Only connect ADN C1 and ADN D1 conference units, ADN PS power supplies and
the ADN-W AM antenna module to the connection sockets PORT I , PORT II, DATA
PS and /.
Regardless of the number of conference units and the room size, we recommend
the following procedure for setting up the conference system:
왘 Decide if you require wired or mobile wireless conference units. You can also
combine wired and wireless conference units.
왘 Plan the number of conference units required for your conference system. A
total of 400 conference units (of which up to 150 can be wireless) can be used
in a conference system (the maximum number of ADN C1 or ADN-W C1 chairperson units is limited to 10). Always take the largest possible number of participants as a starting point.
If you are using wired conference units:
왘 Plan if simple cabling is sufficient or if you require a redundant ring topology
(see page 7).
왘 If necessary, calculate the number of ADN PS power supplies required (a maxi-
mum of 15 ADN PS power supplies can be used in a conference system).
왘 If necessary, calculate the maximum length of the cabling in order to ensure
that all conference units connected are supplied with sufficient voltage (see
page 7).
왘 Place the ADN CU1 central unit and, if necessary, the ADN PS power supplies
e.g. in the electrical equipment room or in the conference room.
왘 Place the conference units at the corresponding seats.
왘 Put out a sufficient number of SDC CBL RJ45 system cables in the required
lengths.
When connecting the conference units to an ADN PS power supply, you can
mix different cable topologies (simple cabling or redundant ring topology)
as long as you ensure correct cabling and comply with the specifications.
If you are using wireless conference units:
왘 Place the ADN CU1 central unit e.g. in the electrical equipment room or in the
conference room. If possible, place the ADN-W AM antenna module directly in
the conference room. The transmission range of the antenna module is approx.
30 m.
왘 Place the operational wireless conference units at the corresponding seats.
In some countries/regions (e.g. Canada), the use of wireless components
operating in the 5.15 to 5.25 GHz frequency band (channel 5 to 8) is
restricted to indoor use.

Setting up a large wired conference system
For conference systems comprising more than 40 conference units or when the
conference units are connected in a redundant ring topology, you require ADN PS
power supplies. A maximum of 15 ADN PS power supplies can be used in a conference system.
Connecting ADN PS power supplies to the ADN CU1 central unit
왘 Use a system cable to connect the PORT II socket or PORT I socket of the
ADN CU1 central unit to the DATA CU/PS input socket of the first ADN PS
power supply (the maximum cable length allowed is 50 m).
왘 Use a system cable to connect the DATA PS output socket of the first ADN PS
power supply to the DATA CU/PS input socket of the second ADN PS power
supply.
왘 Repeat these steps for the remaining ADN PS power supplies.
왘 Connect the conference units to the ADN PS power supply (refer to the instruc-
tion manual of the ADN PS power supply or to the ADN system manual).

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 .
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 24).
왘 Make sure that the “Audio Gain Reduction” function is activated
(see page 24). 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
