Delegate discussion unit (TL-VDQ5600) allows the delegate to talk, request to talk, and register attendance. 1 to 4 delegate microphones can be active simultaneously. Built-in loudspeaker automatically mutes when the microphone is turned on. Chairman discussion unit (TL-VXQ5600) has the additional priority button to override all active delegate units to control the conference.
Multiple chairman and vice-chairman discussion units can be used in one system, and can be active at any time regardless of preset delegate microphone limit.
