CCS-CURD/Control power supply unit
POWER SUPPLY BOSCH CCS900S ( CCS-CURD)
¶ Built-in MP3 recording and playback with graphical display
¶ Patent-pending recording buffer
¶ Digital Acoustic Feedback Suppression
¶ Discussion control without operator
¶ Controls up to 150 contribution devices
¶ Built-in monitor loudspeaker
The Control Unit ( CU) is the heart of the CCS Ultro
Discussion System and supplies the power for all delegate and chairman units in the system. The unit also controls the chairman and delegate unit microphones, as well as
providing connections for audio inputs and outputs.
Functions: Built-in MP3 recording and playback with graphical display ( CCS CURD)
The CU has a built-in recorder to digitally record a discussion to an SD Card. The graphical display shows the status of the recorder and the accompanying buttons can be used to configure the recorder. As an option, the recording is only active when a microphone is active. The SD card can be removed from the CU and processed on a PC for transcription purposes; the recordings can also be retrieved by connecting a PC to the CU’ s USB. The
recordings can be played back to the monitor loudspeaker or to delegate’ s loudspeakers. An audible beep and a flashing LED indicate when the SD Card is almost full and the user needs to replace it with a new card.
Supplies power for up to 50 contribution units
The CU has two trunk outputs for the loop-through connection of contribution units. It is possible to connect 25 contribution units to each trunk output, with a maximum system cable length of 100 m ( 109.3 yards) .
Provides control for up to 150 contribution units
Up to 3 CUs can be used together in a discussion system to power and control a maximum of 150 contribution units. In this configuration a single CU acts as a master controller for the entire system.
