DIS Digital Discussion Systems
CU 5905 Central Unit
Description
The CU 5905 is the controller in the DDS 5900 Digital Discussion System.
It controls and supplies power to the chairman/delegate discussion units
and interpreter units and operates up to 250 discussion units and 32 interpreter units in a single bus cable structure known as the DCS-LAN; a
proprietary high-speed digital audio, data and power bus. All units are connected to the DCS-LAN in daisy chains using standard CAT 5e (or higher)
F/UTP or U/FTP cables.
The CU 5905 features fully digital audio transmission of the floor channel,
two interpretation channels and audio from up to eight discussion microphones at the same time. The audio from units can be combined into four
groups using a built-in group matrix.
The CU 5905 features one analog audio input and four analog audio outputs, the four analog audio outputs are used for distribution of audio from
the four groups, the floor channel or one of the two interpreter channels.
This is used either for connection to external PA systems, for recording
purposes or for connection to a language distribution system, like the DIS
digital wireless infrared system.
The sound for the built-in loudspeakers in the discussion units is taken
from Group A and/or from the Analog Audio In 1 XLR sockets.
Connection for Emergency Input (EEM) is available as well, using Analog
Audio In 2 and the contact closure switch. When activated the signal on
Analog Audio In 2 is available in the loudspeakers and in the headphones.
The OLED display on the front enables the user to setup basic system
configurations in terms of the maximum number of speakers/requests, microphone operation mode etc.
All system settings are available in a web browser interface. The CU 5905
provides TCP/IP communication for external control over Ethernet.
The DCS-LAN chain can be branched using repeater RP 6004 or extension unit EX 6010. Additional units can be powered using power supplies
PS 6000 or extension unit EX 6010
Inserting JB 6104 junction boxes in the DCS-LAN chain enables hot plugging of single units. Each JB 6104 junction box features the connection of
a single unit to each of the four outputs on the junction box.
Features
The CU 5905 has the following features:
• Fully digital audio transmission
• Support for four microphone operation modes; Automatic, FIFO Manual
and VOX (Voice activated On/Off of the microphone)
• Support for delegate interrupt mode

• Scrambled audio to prevent eavesdropping
• Powers up to 60 units without the use of an additional power supply
• Control of up to 250 discussion units
• Connection of up to 32 interpreter units
• Up to eight simultaneous open microphones
• Floor + two interpretation channels
• Four analog audio outputs, configurable as a 'group out' or
'interpretation channels out'
• DCS-LAN daisy chain topology with loop-through connections or hot
plug connection, when using JB 6104 junction boxes
• DCS-LAN connection using shielded CAT 5e (or higher) F/UTP or U/
FTP cabling
• TCP/IP Ethernet connection for external control
• Web browser interface for easy setup of the system
• Web browser interface for microphone control, request list control and
basic operational parameters
• Built-in seat table for attaching seat numbers to units
• Assigning names to the seats using the web browser
