2 Introduction
The CCS 900 Ultro Discussion System is a discussion system for use in meeting and
conference venues with a limited number of participants.
A CCS 900 Ultro Discussion System consists of:
– One Control Unit (CU).
– Maximum 50 units of which one or more Chairman Unit(s).
– Extension cables if required (5m or 10m).
– Peripheral audio and/or telecommunication equipment.
– A built-in MP3 recorder.
The CU is the heart of the discussion system which controls the microphones of the Chairman
and Delegate Units as well as providing facilities for audio inputs and outputs. It also supplies
the power for the CU itself, Chairman Unit(s) and Delegate Unit(s).
With the use of Digital Acoustic Feedback Suppression the loudspeaker volume can be
increased significantly before feedback appears. A Digital Acoustic Feedback Suppressor is
only available in CCS-CUD / CCS-CURD.
A Delegate Unit enables participants to actively join in a discussion (i.e. speaking and
listening) by means of a microphone, controlled by an on/off button and a built-in loudspeaker
or external headphone.
A Chairman Unit has the same function as a Delegate Unit with the addition of a 'Priority'
button, that enables its operator to control the debate by temporary or permanently
overruling and muting all active microphones, depending on an internal setting in the
Chairman Unit.
The built-in MP3 recorder enables participants to: record discussions; listen to discussions
before playing it back to the floor; play discussions back to delegates.
