The Control Unit (CU) is the heart of the CCS 800 Ultro

Discussion System and supplies the power for all delegate

and chairman units in the system. The unit also controls the

chairman and delegate unit microphones, as well as

providing connections for audio inputs and outputs.

Functions

Built-in MP3 recording and playback with graphical

display

The CU has a built-in recorder to digitally record a

discussion to an SD Card. The graphical display shows the

status of the recorder and the accompanying buttons can

be used to configure the recorder. As an option, the

recording is only active when a microphone is active.

The SD card can be removed from the CU and processed on

a PC for transcription purposes; the recordings can also be

retrieved by connecting a PC to the CU’s USB. The

recordings can be played back to the monitor loudspeaker

or to delegate’s loudspeakers. An audible beep and a

flashing LED indicate when the SD Card is almost full and

the user needs to replace it with a new card.

Patent-pending recording buffer

A card can be replaced by an empty card while recording is

running. When the full card is removed, the recording is

continued to a patent-pending recording buffer. When a

new card is inserted into the CU, the buffered recording is

written onto the new card and the recording continues

normally. This gives seamless recording without the loss of

any audio while an SD Card is exchanged.

Digital acoustic feedback suppression

The digital acoustic feedback suppression facility

automatically eliminates acoustic feedback (also known as

‘howling’ or ‘Larson effect’). This gives better speech

intelligibility by allowing the speaker volume to be turned

up as loud as required without any risk of feedback.

Discussion control without operator

The CU can be setup to operate standalone without the

need for an operator. The following 5 modes can be chosen

using a rotary control on the unit’s top panel:

•

Open mode – allows selection of one to four

microphones (excluded chairmen microphones) which

can be simultaneously active

•

Open mode with auto-switch-off – allows selection of

one to four microphones (excluded chairmen

microphones) which can be simultaneously active. If the

delegate does not speak for 30 seconds, microphones

are automatically switched off

•

Override mode – delegates can override each other

simply by activating their microphones. Only one

microphone can be active at any one time. (Note: In

override mode, delegates cannot override chairmen)

•

Chairman only mode – only chairmen can speak.

Delegate microphones cannot be activated, even when

a chairman is not speaking

•

Test mode –checks if system connections are correct.

All microphone light rings and contribution unit LEDs

light up to indicate that units are properly connected

Supplies power for up to 50 contribution units

The CU has two trunk outputs for the loop-through

connection of contribution units. It is possible to connect

25 contribution units to each trunk output, with a maximum

system cable length of 100 m (109.3 yards).

Provides control for up to 150 contribution units

Up to 3 CUs can be used together in a discussion system to

power and control a maximum of 150 contribution units. In

this configuration a single CU acts as a master controller for

the entire system.

Built-in monitor loudspeaker

The built-in monitor loudspeaker and headphone socket

allow the conference to be monitored.

Interfaces the system with external equipment

The following equipment can be interfaced to the CCS 800

Ultro Discussion System through the CU:

•

External wired or wireless microphone – for guest

speakers or audience participation. (Note: The external

microphone is muted when the priority button on a

chairman unit is pressed, and when the system is

operating in ‘chairman only’ mode)

•

External PA system – for transmitting the proceedings

to an audience in the same room or an adjacent room
