Important safety instructions

Hazard warnings on the rear of the central unit

The label shown on the left is attached to the rear of the central unit. The symbols on this label have the following meaning:

This symbol is intended to alert the user to the presence of uninsulated dangerous voltage within the central unit’s enclosure that may be of sufficient magnitude to constitute risk of fire or electric shock.

This symbol is intended to alert the user to the risk of electric shock if the central unit is opened. There are no user serviceable parts inside. Refer servicing to qualified personnel only.

This symbol is intended to alert the user to the presence of important operating and maintenance instructions in the literature accompanying this product.

Overloading

Do not overload wall outlets and extension cords as this tric shock.

Safety check

Upon completion of any service or repairs to to perform safety checks to determine that the device is in safe operating order.

Danger of hearing damage due to high volumes

When the conference participants listen to the floor channel via headphones, they can adjust the volume themselves. In doing so, sound pressure exceeding 85 dB(A) can be produced. 85 dB(A) is the sound pressure corresponding to the maximum permissible volume which is by law (in some countries) allowed to affect your hearing for the duration of a working day. It is used as a basis according to the specifications of industrial medicine. Higher volumes or longer durations can damage your hearing. At higher volumes, the duration must be shortened in order to prevent hearing damage. The following are sure signs that you have been subjected to excessive noise for too long a time:

• You can hear ringing or whistl

• You have the impression (even for a short time only) that you can no longer hear high notes.

Inform the conference participants about these facts and, if set the volume to a medium level.

Structuring and controlling the conference system

Structuring the conference system

The ADN conference system is suitable for sm approx. 30 conference units (divided up onto the two connection sockets PORT I and PORT II). Delegate units and chairman units can order and are connected to the central unit using SDC CBL RJ-45 system cables. The ends of the cable strings are open (no ring topology). The maximum number of conference units that can be used depends on the voltage supply which in turn is influenced by the cable lengths (see next chapter).

all to medium size conferences with

be combined in an arbitrary

In addition, you can connect audio devices to the central unit in order to e.g. feed audio signals to the floor channel or to output the floor channel via an external audio device.

Calculating the voltage drop on the system cables

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 and the first conference unit is 80 m max. and the stand

ard cable length between the conference units is 2-5 m. If these cable lengths are observed, safe operation of a conference system with 30 conference units is ensured. If cable lengths are shorter, it might be that more conference units can be used.

ate

The “ADN Cable Calculator” program allows you to calcul

the voltage drops on the individual sections of a cable string and to plan the structure of the conference system. The program is available from your Sennheiser partner or from the download area on our website at www.sennheiser.com.

To use the “ADN Cable Calculator” program:

왘 Start the “ADN Cable Calculator.exe” file and follow the instructions of the

ram.

For further information and for how to calculate the voltage drop of a cable str

ing,

refer to the help of the “ADN Cable Calculator” program.

Structuring and controlling the conference system

Configuring and controlling the conference system

For configuring the conference system, you can either the central unit or the “Conference Manager” software. The software also allows you to control conferences via a graphical interface:
