Discussion Devices are connected in a daisy-chain configuration to the Control Unit (CCSD-CU or CCSD-CURD) of a CCS 1000 D 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 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.
Function
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
indicate 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.
Microphone with flexible stem
The fixed microphone with flexible stem can be easily
adjusted to suit the user.
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 interface application can be set to
automatically reduce the headphones volume when
the microphone is activated.
GSM immunity
Immunity to mobile phone interference ensures clear,
uninterrupted discussion.
Configurable as a participant device or chairperson
device
The Discussion Device can be quickly configured as a
chairperson 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
sounded to announce that the chairperson is about to
speak.
