The Shure CU 5905 Central Unit is just part of our Shure Digital Discussion system and one of many products available in our rental inventory.

The CU 5905 is the system controller in the DDS 5900 Digital Discussion System. It controls and supplies power to the chairman/delegate/interpreter units while being able to operate up to 250 units. 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 features a fully digital audio transmission of the floor channel as well as two channels of interpretation. Up to 8 conference microphones can be open at the same time which can also be assigned to four groups using a built-in Group matrix.

It also provides one analog audio input and four analog audio outputs. The four analog audio outputs are used for distribution of audio from the four groups of units, 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 wireless language distribution.

Connection for Emergency Input (EEM) is available using Analog Audio In 2 in combination with the contact closure switch. When activated the signal on Analog Audio In 2 will be available in the loudspeakers and in the headphones. The menu on the front enables the user to setup basic system configurations like maximum number of speakers/requests, microphone operation mode, IP address, etc. All system settings as well as microphone control are available in a web browser interface provided through TCP/IP communication which also allows for external control over Ethernet.
