Conference and Discussion System Chairman Unit - CH-300

Chairman conference microphone unit perfect for permanent or temporary meetings. Microphone on/ off button, chairman “priority” key, LED lighted ring, flexible 15’’ (40 cm) gooseneck, and integrated speaker.


The CH-300 Chairman Unit enables the chairperson or moderator to participate in a discussion by speaking through a microphone. It can be activated or deactivated by pressing the microphone ON/OFF push-button. The chairperson can listen to the discussion through the internal loudspeaker or the external headphone. It also features a “priority button,” which enables the chairperson to control the discussion by temporarily or permanently overriding and deactivating all active delegate units. When the microphone is active, an LED ring lights up to visually indicate the microphone ON status.

The chairman unit can be connected to any other chairman or delegate units through the attached single cable. The last microphone unit in the series is connected to the control unit to complete the loop.
