About the VoiceLift System
The VoiceLift System is a low-power classroom microphone amplification system (also
referred to as a “soundfield system”) that enables a teacher or presenter to be clearly
heard at a comfortable level throughout the entire room. The pendant or handheld
microphone picks up speech from the teacher or student and transmits it via IR signal
to the receiver. From the receiver, the signal is fed to an Extron PoleVault switcher. The
switcher functions as an amplifier and powers strategically placed speakers to improve
the signal-to-noise ratio of the voice of the speaker to at least +15 dB.
System Components
The VoiceLift System consists of the following components:
• Microphone (VLP 202 or VLH 102) — The pendant microphone (VLP 202) is worn
by the teacher or presenter on a lanyard around the neck, but can also be handheld
or clipped to clothing if desired. The handheld microphone (VLH 102) cannot be worn
on a lanyard. Each microphone features volume control, a power switch, and an
auxiliary line input connector to feed in a source (such as an MP3 player).
