About the VoiceLift System

The VoiceLift System is a low-power classroom microphone amplification system that
enables a teacher or presenter to be clearly heard at a comfortable level throughout
the entire room (also referred to as a "soundfield system"). 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 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.

Application Diagrams
VoiceLift System refers to the entire system, which includes the pendant or handheld
microphones, the receiver, the charging station, and any secondary receivers.
Receiver refers to the VLR 102 infrared (IR) receiver, which mounts onto a wall or
ceiling.
Secondary receiver refers to the optional additional receiver (VLR 102SR). One
to three secondary receivers can be installed to expand coverage in a large or
odd-shaped room.
Charging station refers to the VLC 102 or VLC 202 charger for the microphone.
Microphone (VLP 102 or VLH 102) — The pendant microphone (VLP 102) is worn
by the teacher or presenter on a lanyard around the neck. The handheld microphone
(VLH 102) is held by the student; it cannot be worn on a lanyard. Both microphones
feature volume control, a power switch, and an auxiliary line input connector to feed
in a source (such as an MP3 player).
The pendant microphone also has an auxiliary input port to support an optional boom
or lapel microphone. Pendant microphones can be hand held for use by students, if
desired.
For descriptions of the two VoiceLift microphones, see "Microphones" in the
"Features and Operation" section.
