The Constellation systems are extensive acoustic systems, which are usually used for larger venues such as concert halls, theaters and much more. Using them in a teaching context means that all students will be able to get the most out of every lecture, regardless of where they sit in the room. Because small microphones and speakers are placed discreetly throughout the lecture hall, the teachers voice is picked up clearly and without noise and can be heard clearly in all corners and nooks of the hall. And if the students have questions, everyone in the room will also be able to hear both questions and answers, without the use of hand-held microphones or anything else that could disrupt the flow of the lesson.
