Discussion Devices are connected in a daisy‑chain configuration to the Control Unit of a CCS 1000 Digital Discussion System. Their plug‑and‑play functionality allows them to be conveniently connected to and removed from the system as required. A power down or restart of the system is not necessary, which ensures for fast installation and reconfiguration times. Participants can take part in a discussion by speaking into the microphone and listening to proceedings through the built‑in loudspeaker or (optional) headphones.

Bosch CCSD-DS CCS 1000 D Discussion Device with Short Microphone

Color: Black
  • Possible-to-speak indication

    A white possible‑to‑speak indicator above the microphone button indicates when the microphone can be activated.

    Request‑to‑speak indication

    A green request‑to‑speak indicator above the microphone button and in the head of the microphone indicates when a request‑to‑speak has been added to the waiting list. The indicators flash green when the request‑to‑speak is first in the waiting list.

    Short or long microphone with flexible stem

    The fixed microphone with flexible stem can be easily adjusted to suit the user. For maximum comfort, a short 310 mm (12.2 in) or long 480 mm (18.9 in)microphone stem is available. Built-in loudspeaker with volume control To ensure for optimum intelligibility, the loudspeaker volume of all Discussion Devices is centrally controlled from the Control Unit.

    Face-to-face meeting feeling

    An authentic face‑to‑face meeting feeling is achieved by allowing the loudspeaker and microphone to be on at the same time.

    Headphones socket

    The built‑in 3.5 mm (0.14 in) stereo headphones socket enables the speaker to be clearly heard, even when there is excessive background noise.

    Built‑in volume control for headphones

    For maximum comfort, the headphones volume can be adjusted by means of a rotary thumbwheel on the side of the Discussion Device. To prevent acoustic feedback from headphones to microphone, an option in the web browser application can be set to automatically reduce the headphones volume when the microphone is activated.

    GSM immunity

    Immunity to mobile phone interference ensures for clear, uninterrupted discussion.

    Configurable as a participant or chairperson’s device

    The Discussion Device can be quickly configured as a ‘chairperson’s device’, which enables a user to function as the chairperson at a meeting. No restart of the system is required. During a discussion, the chairperson can press and hold in the priority button to overrule all participant microphones. A chime is also sounded to announce that the chairperson is about to speak.
