The ADN CU1 central unit
The ADN CU1 central unit is part of the Sennheiser ADN conference system.
The central unit controls the operation of the entire conference system. For wired
operation, up to max. 40 ADN D1 delegate units and ADN C1 chairperson units can
be directly connected to the central unit. For larger wired conference systems with
up to max. 400 conference units, the central unit can also manage up to 15 ADN PS
power supplies which in turn supply power the wired conference units.
For wireless conferencing, you can operate up to 150 ADN-W C1 and ADN-W D1
wireless conference units. For this, you require at least one ADN-W AM antenna
module per central unit. With one antenna module, you can operate a maximum of
75 wireless conference units. Depending on room conditions, you may require several antenna modules. Please note that you can connect a maximum of four
antenna modules to one central unit.
For configuring the conference system, you can either use the central unit’s operating menu 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.
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

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 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 conference 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.
