11.2 Setting up a stand-alone system

The Central Control unit, in stand alone systems enables four basic conference procedures to be conducted:

•Microphone management using various microphone operating procedures,

•Voting procedures using the basic parliamentary voting procedure,

•Interpretation facilities,

•Intercom to the Intercom Operator.

The programming of the interpretation system (i.e. interpreter desk) in a stand-alone system is done manually (see Chapter 11.11 “Programming the interpreter desk”).

2. .‘Override’ mode

When the ‘Override mode is selected, delegates activate their microphones by pressing the microphone button on their delegate units. If the number of active microphones is four and the number of current speakers is three then the delegate can join in the debate without interrupting the group of speakers. However if the number of current speakers is four and a new delegate now presses his microphone button to join in the debate, the microphone unit of the first speaker in the group will be switched off (FIFO First-In-First-Out), allowing the new delegate to join in the discussion. Using the override mode, no ‘Request-to-speak’ list is available.

NOTE: In ‘Open’ and ‘Override’ mode the chairman can, at anytime, switch on his micro- phone.

11.2.1 System mode selection (Multi-CCU LBB 3500/35 only)

Refer to FIG 11-2(4). Single or Multi-CCU mode can be centrally selected using Multi-CCU software package LBB 3586. Using the ‘System’ mode push-button, the Multi-CCU LBB 3500/35 can be selected for use in Single mode if the LED indication for Multi-CCU mode is seen to flash.

11.2.2 Microphone control modes (FIG 11-2(2))

The CCU in stand-alone mode, offers three microphone operational modes:

•‘Open’,

•‘Override’,

•‘Voice activation’.

In each mode of operation, the maximum number of active microphones (Active Micro’s) that can be switched on at the same time during a discussion, can be assigned.

To select the number of active microphones, press the ‘Active Micro’s’ button, its LED corresponding to the chosen number (1, 2 or 4*) will illuminate.

* The number of active microphones available for selection in Voice activation mode is (2 or 4).

1. ‘Open’ mode

When the ‘Open’ mode is selected, delegates activate their microphones by pressing the microphone button on their delegate units.The number of delegates permitted to speak at the same time is limited to the number of active microphones selected.This means for example, - that if 4 Active Micro’s have been selected and four delegates are currently speaking, no other delegates may join in the debate. If a fifth delegate wants to join in the debate, this delegates joins a ‘Request-to-speak’ list However, if one of the current speakers switches his microphone off, the next delegate to switch on his microphone can join in the debate.

The maximum number of delegates in the Request-to-Speak list is 20.

3. ‘Voice Activation’ mode (Single CCU systems only)

When the ‘Voice Activation’ mode is selected, the delegates’ microphones are activated when spoken into. However, its light ring indicator is not functional in this mode (*default). The number of delegates permitted to speak at the same time in this mode, is limited to the number of active microphones selected (2 - 4 only). * The default setting can be changed, see Chapter 2.3.1 and Chapter 2.5.1.
