Beyerdynamic Orbis CU
Orbis CU Digital Control Unit for conferencing
The Orbis conference system features a simple and intuitive operation as well as an easy setting up.
The Orbis CU control unit is used to control a maximum of 100 microphone units with loudspeakers which are connected in two lines to the control unit via RJ45 connections. When connecting a maximum of 50 microphone units in a ring, the Orbis system provides maximum reliability due to redundancy, i.e. the microphone units are supplied with signals from two sides. Should a defect occur in the cables on one side, the microphone units are still supplied from the other side.
Depending on the selected setting and operating mode, a maximum of 8 microphone units (e.g. 7 delegate and 1 chairman unit) can be turned on simultaneously. One audio channel is permanently allocated to each chairman unit in the system so that a maximum of 8 chairman microphone units can be used in one system.
There is a continuous status check, monitoring or control via the data link to the microphone units. E.g. individual microphone units can be activated via the serial interface (RS232) or the whole discussion system can be turned on via a control command or the rotary encoder on the front.
The control unit can be connected to a media control system via the RS232 interface allowing a convenient operation and different status displays. Furthermore, the Orbis system can be integrated into tele or video conferencing systems.
The following operating modes can be selected on the control unit:
Each participant can turn on his/her microphone until the maximum number of open microphones is achieved.
The microphone is automatically turned on when the participant speaks into it, until the number of open microphones is achieved.
Each participant can turn on his/her microphone. If the selected number of open microphones (NOM) is exceeded, the microphone of the participant who turned on his/her microphone first is turned off when another participant turns on his/her microphone.
The rotary encoder allows an easy navigation through the different menus and settings in the individuals menus as well as configurations in conjunction with the REC button. Due to the illumination the user can see all functions at a glance.
An illuminated corona around the rotary encoder displays the operating or standby mode. An SD card insertion and the REC button are used for recording a meeting. The recording time depends on the memory capacity of the SD card: per 1 GB approximately 4 hours of the meeting are recorded. The status line displays an external device connected to the RS232 interface, occuring errors, if a lock has been set and when updating the firmware. Each data file can have a maximum size of 2 GB, then another data file will be created.
By using the optional 19″ rack adapter the Orbis CU control unit can also be mounted in a 19″ rack.
