This document describes an audio enhancement sound system that provides benefits for teachers, students, and administrators. It includes a teacher microphone, student microphones, and a receiver/amplifier. The teacher microphone has features like volume control, input selection, and battery level display. The student microphones are either handheld or lavalier style and have push-to-talk or constant talk modes. The receiver amplifies and distributes audio throughout the classroom and provides equalization and volume controls for different sources. The system aims to improve classroom instruction and learning by enhancing sound quality and teacher-student engagement.

back through the system, it is too loud
• Use a partner to help get the initial level
set in the room
– Have partner wear microphone and talk in a

– Stand across from each other in the room, and
adjust level
– Switch and wear microphone while partner
listens
