JTS CS-1CH ไมค์โครโฟนชุดประธานก้านยาว 15 นิ้ว 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. 

FEATURES

A CS-1 i-Conference Discussion System consists of:

• One Control and power supply unit (CU)
• Maximum 150 delegate or chairman units
• Peripheral audio and/or telecommunication equipment.

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.

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 discussion by the internal loudspeaker and external headphone.

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.
