One hundred public address systems, which consist of a handheld microphone, a lapel microphone and a portable speaker will be distributed to faculty. One PA system will go into each of the 88 classrooms that we have listed on our roster, after the STS team validates the PA system functioning. STS will then have training sessions for faculty and in-classroom documentation on the use of each PA system. There will be an additional 12 PA systems that are available on request.
