The D6221/D6222 Desktop Speaking & Voting Chairman/Delegate Units integrate speech, voting, and check-in functions with a high-sensitivity cardioid microphone and a bright LCD screen for clear and reliable conference operation. The built-in speaker automatically mutes when the microphone is active to prevent feedback, and dual headphone jacks allow adjustable monitoring. Connected via a dedicated 8-core DIN interface, the units support automatic camera tracking and multiple connection topologies, making them ideal for modern digital conference systems. The chairman unit provides priority and podium functions to efficiently manage the flow of meetings.
