Structuring and controlling the conference system
Structuring and controlling the
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 arbi-
trary order. The number of chairperson units, however, is limited to 10 max. per
conference system. All wired components of the conference system are intercon-
nected 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 part-
ner 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.

Structuring and controlling the conference system
8 | ADN CU1
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 inter-
connected in two cable strings which are directly connected to the central unit.
Large conference system with simple cabling
For setting up a large conference system with the maximum number of conference
units (i.e. up to 400), you require one ADN CU1 central unit for controlling the con-
ference and additional ADN PS power supplies for powering the conference units.
The conference units are interconnected in cable strings and up to four cable
strings can be connected to each ADN PS power supply.

Structuring and controlling the conference system
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 inter-
connected in rings and two rings can be connected to each ADN PS power supply.
When connecting the conference units to an ADN PS power supply, you can
mix different cable topologies (simple cabling with cable strings or redun-
dant ring topology) as long as you ensure correct cabling and comply with
the specifications.

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 150 wireless con-
ference 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 (up to wireless 150 conference units
can be used), you require one ADN CU1 central unit for controlling the conference
and one ADN-W AM antenna module for operating the wireless conference units
(range approx. 30 m).
ADN C1 and ADN D1 wired conference units and ADN-W C1 and ADN-W D1
wireless conference units can be combined arbitrarily as long as you ensure
correct set-up and cabling and comply with the specifications (a conference
system can comprise a total of 400 conference units of which up to 150 can
be wireless).

Structuring and controlling the 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. However, the full function-
ality of a wireless conference system can only be configured using the “Conference
Manager” software. The software also allows you to control and monitor confer-
ences 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).
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 sys-
tem. 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
Setting up the conference system
Regardless of the number of conference units and the room size, we recommend
the following procedure for setting up the conference system:
왘Decide if you require wired or mobile wireless conference units. You can also
combine wired and wireless conference units.
왘Plan 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 chair-
person units is limited to 10). Always take the largest possible number of par-
ticipants as a starting point.
If you are using wired conference units:
왘Plan if simple cabling is sufficient or if you require a redundant ring topology
(see page 7).
왘If 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).
왘If 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).
왘Place 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.
왘Place the conference units at the corresponding seats.
왘Put out a sufficient number of SDC CBL RJ45 system cables in the required
lengths.
If you are using wireless conference units:
왘Place 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.
왘Place the operational wireless conference units at the corresponding seats.
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.
왘Only 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 /.
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.
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 the conference system
14 | ADN CU1
Setting up a small wired conference system with only
the central unit
For a small wired conference system, you do not require ADN PS power supplies.
Connecting conference units connected in a cable string to the ADN CU1
central unit
The following describes how to connect one cable string to the ADN CU1 central
unit. If necessary, repeat these steps for a second cable string.
왘Use a system cable to connect the PORT II socket or PORT I socket of the
ADN CU1 central unit to the IN socket of the first conference unit.
왘Use a system cable to connect the OUT socket of the first conference unit to
the IN socket of the second conference unit.
왘Repeat these steps for additional conference units.
왘If necessary, repeat all steps for a second cable string.
Please note that there is a limited number of approx. 15-20 conference
units per cable string due to the voltage drop on the cable string (see
page 7).
You can use optional cable holders for guiding the system cables. For
detailed information, refer to the ADN system manual.
