Section 3: CS 5 BU Base Unit

3.1 General

The CS5 BU is the Base Unit required for any CS 5 system configuration. It synchronizes all system components and generates the floor audio channel. you can connect to the Base Unit up to 5,000 microphone stations (Delegate Sta- tions, Chairperson Stations, and Interpreter Stations); external analog audio sources; an external amplifier; an audio recording device; and one or more infrared radiators.

The CS 5 BU provides the following basic control functions:

-NOM limitation: maximum number of microphones that may be open at any time, selectable from 1 to 64

-Two selectable automatic microphone activation modes

-Voting initiated from a Chairperson Station

-Driving the infrared radiator panels

More control functions are available through computer control using the CS5 ConferControl software.

1SYSTEM: Sets the level of the sum of all open microphones on the microphone stations.

2 LINE: Sets the level of the rear panel LINE IN line level input.

3 EXT. MIC: Sets the level of the rear panel EXT. MIC IN microphone level input.

4 TAPE: Sets the level of the rear panel TAPE IN input for an external audio source.

5 TELEPHONE: Sets the level of the rear panel TEL. IN input for an external telephone hybrid.

6 LANG. EXT.: Sets the level of the rear panel EXT. LANG. IN input for an external hardwire or wireless microphone used by an interpreter working outside the interpretation booths.

7 NOM LIMIT: Sets the maximum number of microphones (NOM) that may be open simultaneously at any time and the number of audio channels available for interpretation. "1/63" means one open microphone and 63 interpre- tation channels, "64/0" means 64 open microphones and no interpretation channel.

8 SPEAKERS: Sets the level of the signal fed to the loudspeakers on the microphone stations.

9 LED level meter indicating the level set by the SPEAKERS control (8). Set the SPEAKERS control (8) so that the red Peak LED will only flash occasionally at very loud signals.

10 MAIN: Sets the level of the rear panel LINE OUT line-level output.

11 LED level meter indicating the level set by the MAIN control (9). Set the MAIN control (9) so that the red Peak LED will only flash occasionally at very loud signals.

12 HEADPHONE: Sets the level of the headphone output (14) to the right of the HEADPHONE control.

13 Status LEDs: The CS 5 BU provides three status LEDS:

POWER (green) is lit to indicate that power to the Base Unit is ON. REMOTE (yellow) flashes to indicate that data is being transmitted. NOM LIMIT (yellow) flashes to indicate a synchronization error.

Upon powering up, the REMOTE and NOM LIMIT LEDs will flash alternately for a few seconds to indicate the sys- tem is synchronizing and go out as soon as synchronization is completed.

14 : ¼" TRS headphone jack for stereo headphones only. (Using mono headphones may damage the unit.)

15 POWER: Switches power to the Base Unit ON ("I") or OFF ("0").
