The Indicator3 is the successor of the Indicator2 by Interspace Industries. The “traffic light” signalling system reliably supports speakers, moderators and presenters in the successful execution of a presentation. Green, orange and red light signals visually announce the remaining speaking time to the presenter.
The device is connected (up to 100 m) via standard microphone cables and is supplied with one to two display units, which can be controlled separately.
