Sennheiser ADN D1 Delegate Unit

Push to talk microphone system.

The Sennheiser ADN D1 is a digital delegate unit with a super-cardioid gooseneck microphone, integrated twin loudspeakers and a 3.5mm stereo jack headphone socket.

The ADN D1 has an LED illuminated microphone talk button and signal light ring to visually notify delegates, the chairperson, and any other audience members during a meeting. For example, after pressing the speak button a green flashing microphone LED will notify a user that their request to speak has been made, and the signal light ring at the top of the gooseneck can be set to flash red to show all other participants that the user wishes to speak.
