DESCRIPTIONFeatures
The Extron VoiceLift Microphone integrates seamlessly into new or existing PoleVault installations, as well as new VoiceLift Systems. The VoiceLift Microphone series of products includes a wireless pendant microphone, receivers, and charging station.
The lightweight pendant microphones can be worn around the neck or clipped on clothing. The teacher’s voice is picked up by the microphone and transmitted wirelessly to a receiver mounted on the ceiling or wall. The signal is then passed to an Extron PoleVault Switcher or VoiceLift Amplifier where it is amplified and distributed to speakers placed throughout in the classroom, enabling teachers to be heard clearly without shouting or straining their voices.
The microphone uses infrared signals for transmitting the teacher’s voice to the receiver. Infrared signals do not pass through walls and are not subject to interference, offering clear advantages over systems that use radio frequency technology. An optional secondary IR receiver is available for large rooms. Up to two microphones can be supported per classroom, promoting team teaching or student participation.
Each microphone includes a single, rechargeable 2500 mAh NiMH
AAbattery that provides up to 8 hours of talk time. A standard alkaline AA battery can also be used. The desktop charging station charges two microphones and protects them when not in use.

What is a Sound Field?
A sound field is the area within a classroom where the teacher’s voice and program material are distributed at a consistent level to each student. A sound field is created by a classroom sound system specifically designed to slightly amplify the teacher’s voice using speakers strategically placed throughout the room. The key to success is not simply amplification, but increased intelligibility. To achieve this goal, effective sound field systems must accomplish the following:
nAmplify the teacher’s voice slightly above classroom background noise
nDistribute sound evenly throughout the entire classroom by using multiple speakers
nProvide superior audio performance in frequencies associated with the human voice
nMaximize speech intelligibility
