Bosch CCS900 ِDigital Series
Digital Conference System with Auto Tracking
The Bosch CCS-CU Control Unit is the central power and control station for all CCS 900 Ultro Conference System contributor units, such as the chairman and delegate units. The control unit will supply power for up to 50 delegate / chairman units. The unit features a built in speaker and automated, programmable control over contributor units without the need for an operator. Plenty of connections allow for interfacing within paging systems, amplifier systems, recording devices and more. The unit is feature rich, however its control section is straightforward and intuitive to operate in any conference setting.
Digital Acoustic Feedback Suppression
The digital acoustic feedback suppression facility automatically eliminates acoustic feedback (also known as ‘howling’ or ‘Larsen 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
