The ADN PS power supply
The ADN PS power supply is part of the Sennheiser ADN conference system.
For large conference systems with up to 400 conference units, you require ADN PS
power supplies. A max. of 15 ADN PS power supplies can be used in a conference
system. When the conference units are connected in simple strings, one ADN PS
power supply can power up to 70 conference units. When the conference units are
connected in ring topology, one ADN PS power supply can power a max. of
40 conference units.

Structuring and controlling the conference system
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
arbitrary 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.

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
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”.

Setting up the power supply
CAUTION
Danger of material damage and personal injury due to stacked
power supplies!
When stacking several ADN PS power supplies on top of each other,
•
•
the stack may topple over,
the temperature of the individual ADN PS power supplies may
drastically increase,
•
high mechanical loading may be exerted on e.g. the housings,
cables or installation surfaces.
This can cause material damage and personal injury.
̈ Never stack several ADN PS power supplies on top of each other.
̈ Make sure that the air vents are not covered or blocked.
̈ Place the ADN PS power supply on a flat surface as shown.
IFor information on how to mount the power supply into a 19” rack, refer to
the detailed instruction manual “ADN Conference System”.
Connecting the ADN PS power supply to the mains power supply
CAUTION
Product damage due to unsuitable mains cables or power outlets!
An unsuitable power supply can damage the product.
̈ Use the mains cable (supplied) for connecting the product to the mains power
supply.
̈ Only use multi-outlet power strips or extension cables with protective ground
contacts.
̈ Only use mains cables with a 3-pin connector.
C
̈ First connect the mains cable (supplied) to the mains socket

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 and PORT II, the network devices can be
damaged due to an unsuitable power supply.
̈ Only connect ADN C1 and ADN D1 conference units to the connection sockets
PORT I and PORT II.
Basic information on the set-up of 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:
̈ Plan the number of conference units required for your conference system.
A total of 400 conference units can be used in a conference system (the
number of ADN C1 chairperson units is limited to 10 max.). Always take the
largest possible number of participants as a starting point.
̈ Plan if simple cabling is sufficient or if you require a redundant ring topology
(see page 5).
̈ If necessary, calculate the number of ADN PS power supplies required (a max.
of 15 ADN PS power supplies can be used in a conference system).
̈ 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).
̈ Place the ADN CU1 central unit and, if necessary, the ADN PS power supplies in
the electrical equipment room.
̈ Place the conference units at the corresponding seats.
̈ Put out a sufficient number of SDC CBL RJ45 system cables in the required
lengths.
Setting up a small conference system with only the central unit
For a small conference system, you do not require ADN PS power supplies. The
conference units can be directly connected to the ADN CU1 central unit (refer to the
quick guide of the ADN CU1 central unit or to the detailed instruction manual “ADN
Conference System”).

conference units connected in redundant ring topology
In large conference systems with up to 400 conference units, 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. When the conference units are connected in ring topology, one ADN PS
power supply can power approx. 30-40 conference units.
To ensure full operational reliability in a redundant ring topology, the
hardware of the ADN C1 and ADN D1 has been revised. If you combine
conference units with hardware revision 1 (no marking on the type plate)
and conference units with hardware revision 2 (“HW: v2” is printed on the
type plate), fail-safe operation is only possible to a limited extent.
̈ In a redundant ring topology, only use conference units with hardware
revision 2.
