The Sennheiser ADN D1 Digital Delegate Conferencing Unit is part of Sennheiser's ADN conferencing system. The device connects to the ADN CU1 central unit via Cat 5 cable and functions as a delegate's microphone and playback speaker. The unit features a flexible 15" super-cardioid gooseneck microphone for capturing audio and dual loudspeakers within the base for audio playback. The microphone operates in either direct access mode, wherein any delegate may speak at any time or in "request" mode wherein you must add your name to a list of delegates waiting to speak, and wait to be granted permission by the chairperson.
