u Unique patent pending possible-to-speak indicator

u Plug and play functionality for ensuring fast

installation and reconfiguration times

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.

Functions

Possible-to-speak indication

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

u Compact, attractive ergonomic design

u Easily configured as a participant device or

chairperson device

u Immunity to mobile phone interference

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.
