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 Control and Power Supply Unit (CPSU).

•Maximum 50 units of which one or more chairman unit(s).

•Extension cables if required (5m or 10m).

•Peripheral audio and/or telecommunication equipment.

The CPSU 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 CPSU 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 LBB 3310/10.

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.

3Control and power supply unit (CPSU)

Figure 3.1

1 Mains On/Off switch.

2 Power On LED indicator (green).

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.

Chairman only mode. Only the chairman units can be activated.

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

units will lit, if properly connected.

4 Speaker volume control of all connected delegate and chairman units.

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

6Headphone connection with 3.5 mm stereo jackplug socket.

7Trunk output 1 and 2. For loopthrough 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 CPSU and the last unit in the system is

100 m (328 ft).

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

9Recorder input with gain control and recorder output connection.

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

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

Note

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

12Insertion 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).

Note

Position «1» required for internal loop-through of the microphone signals to the delegate/ chairman unit loudspeakers.

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

14Mains input connection. Use the included mains cord to connect the CPSU 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 colour indication not applicable to mains cords for North America).

9Chairman 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.

Figure 4.1

The chairman unit (B) has the same function as a Delegate unit (A) with the exception of a ‘priority’ button.

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

2Two 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.

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

4 Red (LED) indicator above the microphone push button, for microphone ON indication.

5 7-pole circular female socket for loopthrough 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 CPSU.

7 Rotary volume control for headphones only.

8 Microphone ON/OFF push-button.

Warning

The CPSU must be earthed via the mains supply for safety reasons and to ensure the specified audio performance of the system. Do not open the CPSU and/or delegate/chairman units, no user serviceable parts inside.

5.1Connecting the delegate and chairman units

Figure 5.1

Connect the delegate (2) and chairman (3) units to the trunk connectors of the CPSU (1). Use an extension cable (4) if necessary.

5.3 Locking the extension cable

Figure 5.3

Cable locking clamps can be used in combination with the extension cables to prevent accidental disconnection.

5.4Connecting an external microphone

Figure 5.4

Put the external microphone (2) connector in the microphone input of the CPSU (1).

Adjust the sensitivity by use of the gain control (3). Use only microphones with balanced output.

The microphone input provides a 12V phantom power supply.

5.5Connecting a wireless microphone

Figure 5.5

Connecting a wireless microphone to the external microphone input is possible with the included 50dB attenuator. This way of connection allows interruption of the wireless microphone by the chairman’s priority button.

5.6Recording/play back the conversation

Figure 5.6

Connect the cabling of the tape recorder (2) to the recorder input and output of the CPSU (1). Use the gain control (3) to adjust the sensitivity of the recorder input of the CPSU.

5.7Connecting a PA-system or other external equipment

Figure 5.7

Connect a PA-system (3) or other devices (2) to the inand output of the CPSU (1).

Connect audio sources to the line input, a PA amplifier or other sound-processing devices to the line output.
