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.

3 Control Unit (CU)

Figure 3.1 Control Unit

1. Mains On/Off switch.

2. MP3 recorder (for more information, see section 7).

3. Microphone-mode switch.

Open mode with auto switch-off. To select the maximum number of delegate
microphones to be activated simultaneously (1, 2, 3 or 4).The microphone
automatically switches off if the speaker does not speak for 30 seconds. The
microphone can manually be switched off by pushing the button on the
Delegate Unit.

Open mode. To select the maximum number of delegate microphones to be
activated simultaneously (1, 2, 3 or 4). The microphone must be switched on or
off manually by pushing the button on the Delegate Unit.

Override mode. Only one delegate microphone can be activated. If a new
delegate presses his microphone button, the microphone unit of the current
speaker will be switched off.

Chaiman only mode. Only the Chairman Units can be activated.

Test mode. For proper installation check. All the red LED’s and the light-rings

of the connected units will lit, if properly connected.

4. Speaker volume control of all connected Delegate and Chairman Units.

5. Volume control of the speaker or headphone of the CU.

6. Headphone connection with 3.5 mm stereo jack plug socket.

7. Trunk output 1 and 2. For loop through connection of the Delegate and Chairman Units.
To each output a maximum of 25 units can be connected. The maximum length of cable
between the outputs of the CU and the last unit in the system is 100 m (328 ft.).

8. Microphone input with gain adjustment for external microphone. The external
microphone will be muted when the priority button on the Chairman Unit is pressed.

9. Recorder input with gain control and recorder output connection.

10. Line input and output for connecting a PA-system or other audio equipment.

11. Telephone coupler input and output for connecting a remote participant.

12. Insertion connection. To connect an external audio equalizer for speech quality
improvement under difficult acoustic conditions (1 = without equalizer, 0 = insertion
connection is internally open, providing means to connect an external equalizer in the
path from microphone signals to delegate/chairman loudspeakers).

13. Digital Acoustic Feedback Suppressor (DAFS) switch to activate or deactivate the DAFS
(optional).

14. USB connector. Used for downloading recorded speech to a PC (optional).

15. Mains input connection. Use the included mains cord to connect the CU to the mains
socket. In some countries it may be necessary to replace the supplied mains cable by a
local one. Brown = live, blue = neutral and green/yellow = earth. (Replacement and color
indication not applicable to mains cords for North America).

NOTICE!

The telephone input signal to the CU is not added to the telephone output signal from the CU
to prevent line echo due to feedback.

NOTICE!

Position "1" required for internal loop-through of the microphone signals to the Delegate /
Chairman Unit loudspeakers.

4 Delegate and Chairman Unit

Figure 4.1

The Chairman Unit (B) has the same function as a Delegate Unit (A) with the exception of a
'priority' button and the Possible-To-Speak indication.

1. Microphone with red illuminated indicator ring, lights when the microphone is ON.

2. Two 3.5 mm stereo headphone sockets, one at each side, for headphone or recorder
connection. Insertion of a headphone jack in one or both sockets automatically mutes the
unit's loudspeaker.

3. Built-in loudspeaker, automatically muted when the microphone is on.

4. Bi-color LED indicator above the microphone push button. Red for microphone on, white
for Possible-To-Speak indication (Delegate Unit only).

5. 7-pole circular female socket for loop through connection to the next unit.

6. 2m flying lead connection cable with sturdy moulded 7-pole circular male connector for
connection to the previous unit or CU.

7. Rotary volume control for headphones only.

8. Microphone ON/OFF push-button.

9. Chairman Priority button. When pressed emits chime tone, overrules/mutes all active
microphones of Delegate Units in the system and keeps the chairman's microphone on
for as long as the button is pressed (setting can be changed in the Chairman Unit).
In systems with several Chairman Units these settings are independently selectable for
each Chairman Unit.

5.1 Connecting the Delegate and Chairman Units

Figure 5.1

Connect the Delegate (2) and Chairman (3) Units to the trunk connectors of the CU (1). Use
an extension cable (4) if necessary.

5.2 Connecting up to 150 units

The CCS 900 Ultro can be used with up to 150 units by adding a maximum of 2 additional
Control Units acting as power supply units only. Please contact your local Bosch
representative for the installation instructions.

telephone coupler is further connected to the telephone wall socket (4) and a telephone (3)
for dialing.

A connection to a telephone network must always be made via a telephone coupler that
provides adequate isolation between the telephone network (PBX) and the CCS 900 Ultro
system. The telephone coupler shall also meet all relevant requirements for this type of
communication equipment as imposed by law and/or responsible telecommunication
organizations in the country of use.

CAUTION!
