The CCSD-CURD Control Unit with DAFS & Recorder from Bosch serves as the main component of the CCS 1000 Digital Discussion System. It supplies DC power to all connected discussion devices while monitoring and controlling the discussion system. A touch-button control allows for easy configuration and operation of the unit, while intuitive LED indicators clearly display current system settings.

Conveniently positioned ports at the rear of the unit enable peripheral equipment, such as audio devices and HD conference domes, to be connected to the discussion system. Basic and advanced system settings can be easily viewed and changed via the unit's intuitive web browser interface.

Additionally, this model comes with an integrated MP3 recorder with internal memory and USB recording and uses a built?in Digital Acoustic Feedback Suppression (DAFS) feature to optimize speech intelligibility. The four RCA outputs at the rear of the CCSD-CURD make the unit suitable for recording individual speakers in courtrooms.

Plug-and-Play Functionality

The plug-and-play functionality of the Control Unit allows discussion devices and system cameras to be conveniently connected to and removed from the system as required. A power down or restart of the system is not necessary, which makes for fast installation and reconfiguration.

Web Browser Control

Basic and advanced system settings, including microphone management and recording functions, can be easily viewed and managed/configured by using a web browser in combination with a tablet, laptop, or desktop computer. Changes made in the web browser interface are automatically updated in the Control Unit and vice versa. Via the web browser, the Control Unit and connected devices can be set to be automatically shut down for energy saving purposes. Separate login rights are available for operators and technicians to prevent unauthorized access to system settings.

Open Microphone Control

The maximum number of microphones that can be activated by pressing the microphone buttons on the discussion devices can be selected with the "Number of Open Microphones" (NOM) button on the Control Unit. A maximum of four microphones can be selected on the Control Unit. This can be further extended to 10 microphones in the web browser.

Discussion Control

One of the following microphone modes can be selected by pressing the Microphone Mode button on the front of the Control Unit:

  • Open mode: participants can speak by pressing their microphone buttons. When the maximum number of open microphones is reached, the next participant that presses his microphone button is added to a waiting list. The first participant in the waiting list is allowed to speak when an activated microphone is disabled.
  • Override mode: participants can override each other by pressing their microphone buttons. When the maximum number of open microphones is reached, the next participant that presses his microphone button will deactivate the microphone that has been activated for the longest time (the chairperson's microphone is not included in the number of openmicrophones and, therefore, cannot be overridden by a participant).
  • Voice Activation mode: participants can activate their microphones by speaking into them. A microphone can be temporarily muted by pressing and holding down the microphone button.
  • Push to Talk (PTT) mode: participants can speak by pushing and holding in their microphone buttons. The microphone is deactivated when the microphone button is released. The maximum number of participants that can speak is determined by the number of open microphones.

 

Interface for Peripheral Equipment

The Control Unit enables the following equipment to be connected to the CCS 1000 Digital Discussion System:
  • System cameras: for giving a clear visual overview of the proceedings. A maximum of six Bosch HD Conference Dome cameras can be connected to the system with native support (the camera presets can be configured in the web browser).
  • External wired or wireless microphone: to allow a guest speaker or an audience to participate in a discussion.
  • Sound reinforcement system: for transmitting the proceedings to an audience in the same room or an adjacent room.
  • Audio equipment: for broadcasting music through the loudspeakers of the discussion system.
  • External audio processor: for modifying the floor signal distributed to the participant loudspeakers and headphones (i.e. equalizing).
  • Telephone coupler: to allow a remote participant to join a discussion via a telephone/video connection.
  • External recorder: for recording and playing back discussions.
  • Computer (connected via micro USB connector at rear of Control Unit): for transferring recordings (discussions) from the internal memory of the Control Unit.

 

Built-In MP3 Recorder

The built-in recorder can record discussions in MP3 format to the internal memory or an optional USB memory stick. To ensure that discussions are manageable, recordings are divided into files of one hour duration containing the date and time of recording. LED and audible indicators keep you informed regarding memory and recording status.

Internal Memory

Recordings are automatically saved in the internal memory unless a USB memory stick is connected to the USB port at the front of the Control Unit. The internal memory can record up to eight hours of audio.

USB Memory Stick

Recordings are automatically saved to a USB memory stick when one is connected to the Control Unit. A separately available USB memory stick of 128GB can record up to 4000 hours of discussion time.

Built-In Monitor Loudspeaker

The built-in loudspeaker and headphone socket allows for live monitoring of a meeting from the CCSD-CURD Control Unit, as well as pre-listening of audio files before replaying them to the floor.

Built-in Digital Acoustic Feedback Suppression (DAFS)

The built-in Digital Acoustic Feedback Suppression (DAFS) feature suppresses acoustic feedback (also known as "howling" or "Larsen effect"). This improves speech intelligibility by allowing the speaker volume to be set as loud as required without risk of acoustic feedback.
