The Extron VoiceLift® Microphone System is a voice amplification system specifically developed for K-12 classrooms. The VoiceLift Microphone System enables the creation of a "sound field" that allows a teacher's voice to be heard clearly throughout the classroom. Studies show that use of a sound field system results in increased student achievement and a reduction in teacher health issues related to voice fatigue. Each system contains all the components necessary to evenly distribute the teacher's voice throughout the classroom, including wireless microphone, IR receiver, switcher/amplifier, speakers, and cables.
