Functional Overview of the VoiceLift Microphone
The VoiceLift Microphone is a soundeld system, which is a low-power classroom
amplification system that ensures that the teacher can be clearly heard at a
comfortable level throughout the classroom.
The pendant microphone, worn by the teacher/speaker, picks up speech and
transmits it via IR signal to the receiver. From the receiver, the signal is fed to
a PoleVault switcher/amplier, which powers strategically placed speakers to
improve the signal-to-noise ratio of the teacher’s voice to at least +15 dB.
