CCS 900 Ultro
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.

Volume control of the Delegate and Chairman Units
Figure 6.12
Put the Digital Acoustic Feedback Suppressor switch (1) in position "0" and adjust the

Suppression on by changing the switch (1) to position "1". Then set the loudspeaker volume
to the required level, but increasing the volume level more than 2 or 3 steps is not
recommended.
NOTICE!
With the use of Digital Acoustic Feedback Suppression the loudspeaker volume can be
increased significantly before acoustic feedback appears. The maximum achievable volume
gain depends on the acoustical environment and positioning of the units. Artefacts may occur
during microphone switching at very high volume levels. In general the achievable increased
volume gain is 4 - 6 dB. The Digital Acoustic Feedback Suppression is optimized for speech.

7.1
Introduction
23
NOTICE!
Connect the Control Unit at least ones every 6 months to the mains supply for 24 hours to
keep the MP3 back-up battery charged.
The built-in MP3 recorder allows users to:
–
record discussion
–
listen to discussion before playing it back to the floor
–
play discussion back to delegates
Recording is started and stopped by the user. The settings of the MP3 recorder can be
changed so that recording only takes place when any one of the microphones is active (for
more information, see section 7.3). The MP3 recorder will record the audio from external
devices if connected.
When recording is activated, the MP3 recorder will automatically create an MP3 file, using the
current date and time as the file name. Recorded files have a maximum duration of 60
minutes. After 60 minutes, the file will be automatically closed, and a new file will be created.
This process is repeated as long as recording is active or until the SD card is full.
Recorded speech is saved on an SD card, which is inserted into the top of the unit (see
following figure), or saved internally. After recording, the SD card can be removed, or the
recorded speech can be downloaded to a PC by connecting a USB cable to the back of the
CCS Control Unit.
The MP3 recorder has a card exchange feature that allows the user to exchange the SD card
during conversation without loss of discussion/audio (for a full explanation of this feature, see
section 7.4.3).
Once discussion has been recorded, the user can choose to pre-listen to or playback the file
(for more information, see section 7.5).

Mounting Instructions
The CU can be attached in three different ways:
–
In a 19" rack making use of the 19" rack mounting set LBB 3311/00. Place a blank 1HU
panel above the CU to have sufficient space for cable connections.
–
Mounted into a table using the flush mount bracket.
–
On a table. Therefore drill four holes in the table and fasten the CU with four M3 screws
(B).
The Delegate and Chairman Units can only be attached on a table. Therefore drill two holes in
the table and fasten the unit with two self tapping M3 screws (A).
NOTICE!
When the device is attached to a flat surface it no longer conforms to the UL/CSA approval.
