University Classroom spaces utilize a variety of different equipment to help make a better learning environment. Many of the classrooms have microphones to capture the audio in the room for lecture capture and to enhance audio for easier hearing in large rooms.

Rooms with more than 70 seats most commonly are the ones to receive wireless microphone installs. To see more information about a particular room and what is available check out the Classrooms website.

Learning Spaces Team installs a similar type of microphone in each room. Below is a general overview of each type of microphone.
