Discussion Devices are connected in a daisy‚Äëchain configuration to the Control Unit of a CCS 1000 Digital Discussion System. Their plug‚Äëand‚Äëplay 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‚Äëin loudspeaker or (optional) headphones.
