Conference System  CS-1 System

CS-1CU (Analog Control Unit)


The control unit is the center of the discussion system which controls the microphones of the chairman and delegate units as well as connects to other audio input and output. It also supplies the power for the CU itself, and up to 50 chairman and delegate units.

CS-1CH (Analog Chairman Unit)


The chairman unit not only provides the same function as the delegate unit, but also supports the addition of a “Priority button”, that enables the chairman to control the discussion by temporary or permanently overriding and deactivating all active microphones of the delegate units.

CS-120DU (Digital Delegate Unit)


The delegate unit enables the attendants to participate in a discussion by speaking through a microphone, controlled by a microphone ON/OFF push-button, and listening to discussion by the internal loudspeaker and external headphone.
