1 About this manual
This manual provides all the information required to
install and operate the CCS 800 Ultro Discussion
System.
Conventions
2 Introduction
The CCS 800 Ultro Discussion System is a discussion
system for use in meeting and conference venues with a
limited number of participants.
A CCS 800 Ultro Discussion System consists of:
• One Central 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. Digital Acoustic Feedback
Suppression 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 discussion; listen to discussion before playing it
back to the floor; play discussion back to delegates.
Warning
Warnings draw attention to instructions that
must be followed to prevent personal injury.
Caution
Cautions draw attention to instructions that
must be followed to prevent damage to the
equipment.
Note
Notes draw attention to special instruction tips
or other useful information.

Note
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
optimised for speech.

6.12 Monitoring volume control
Use the built-in loudspeaker or a headphone to monitor
the discussion. Adjust the volume using the monitoring
volume control. The maximum level is controlled by
the setting of the volume control for delegate and
chairman units.
6.13 Using a headphone
Figure 6.13
Use the rotary volume control (1) to adjust the volume
of the headphones connected to the left and/or right
side of the units. Inserting a headphone jack mutes the
loudspeaker.
The maximum level depends on the setting of the
volume control (2) on the CU.

7 Built-in MP3 recorder
7.1 Introduction
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).
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
800 Ultro Central 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).
