SENNHEISER ADN-CU1-EU Digital discussion central unit

The digital discussion central unit ADN CU1 powers and controls up to 40 (depending on cable length) connected delegate and chairperson units. It offers full configuration in a quick and easy way over the menu display in several languages. Alternatively the integrated software package 'Conference Manager' can be used directly on the CU1 by connecting a screen, mouse and keyboard. The intuitive workflow of the conference manager allows a fluent monitoring and control of the conference. With its low-noise fan the central unit can be used directly in the meeting without disturbing it.

• Choice of microphones for every kind of system and room acoustics. 
•  Display and multifunction soft keys for ease of use.
• Up to 63 language channels independently selectable for two users.
• 1, 3, 5-way voting/polling function.
• Dip-switch selectable president and delegate operating modes.

The CS 5 VU provides two operating modes, reducing the number of different components needed for a conference system.

In a small discussion system with CS 5 DU microphone stations, the chairperson would typically use a CS 5 VU. In President mode, it provides a priority function and allows the user to start votes or polls. The display will then indicate the time left for voting and the results.

In a larger conference system, the CS 5 VU can be used both by delegates and by the president. In delegate mode, it provides all voting and language selection functions independently for two delegates. A bank of dip switches allows the CS 5 VU to be set to President mode with priority and 1, 3, or 5-way voting/polling functions. In computer-controlled conference systems, chip-card identification is available as an option.

Gooseneck, capsule and connecting cable are not included.

The unit shall act as chairman unit or normal delegate unit, selectable by a dipswitch on the bottom of the housing. It shall have a built-in microphone and loudspeaker, which allow the forwarding of the voice of the speaker towards the other units of the system. The chairman shall always be able to start 1,3 and 5 step voting from the unit and monitor the results on the unitʼs  display. Priority calls shall also be possible from his unit.

The CS 5 VU is suitable for taking over maximum 63 interpreted languages and the room voice as well, which may be listened to through the headset that is connected to the device. A chip card reader is also included in the unit, with the aid of which it is possible to identify the user of the device in the case of a computer controlled conference.

The backlit graphic LC display facilitates using the device and displays its current status and the result of the vote. The unit shall operate for 2 persons simultaneously, with independent adjustable languages for each of the 2 x 3,5mm stereo jack headphone sockets.

Power (w/o IEC power cord) for up to 40 microphone units.

Infrared radiators providing wireless transmission of up to seven language channels for persons (e.g., observers) listing to a conference without asking for the floor.

The infrared radiators shall connected to the CS 5 BU through 2 BNC connectors and 50 Ohm coaxial cabling and serial concatenation. It shall transmit a  PPM system modulated time-multiplex outputs of the central unit shall drive an arbitrary number of radiators. The CS 5 IRT1 shall have a radiation angle of +/- 22° and a working distance of 300 meters (with 50% down). The CS 5 IRT2 shall have a radiation angle of +/- 22° and a working distance of 500 meters (with 50% down).

As accessories of the infrared radiators the holding frame needed for mounting it to the side wall or the ceiling shall be included. The transmitter shall have a built in switchable power supply with IEC connector.

Interpreter station for use with selectable microphones. Four input channels selectable: floor, two pre-selected languages, relay. An external microphone input allows the station to be used either with a gooseneck microphone and separate headphones or a headset.

Gooseneck, capsule and connecting cable are not included.

The Interpreter unit CS 5 IU has to ensure the technical conditions that are needed for interpreters working in the interpreter booth. Its task is on one side to forward the floor voice or the voice of an other interpreter to the headphone of all the interpreters or to the loudspeakers that are incorporated into the interpreter unit, and on the other side to transmit the text translated by the interpreters to the relevant system channel with the aid of the incorporated microphone.

According to the international prescriptions two interpreter units have to be installed into an interpreter booth in order to allow the continuous working of two interpreters. The following functions must be enabled: listening to 2 preselected channels with the push of one button. Choosing any other channel using "up” and "down” buttons. Output to 2 preselected channels by the push of one button. Possibility to give a sign to the speech holder to slow down as well as to the technician to call for assistance. Input/Output shall be possible via gooseneck microphone and headphone or a suitable headset. The unit shall be connected in the data ring at any point.
