VoiceLift System Audio Signal Path
VLP or VLH Microphone — The VLP 302 and VLH 302 microphone transmits the
voice audio signal to the VLR 302 receiver.
VLR 302 Receiver — The VLR 302 receives the signal from the microphone, and
outputs a balanced mono line level signal (-10 dBV) to the PoleVault switcher.
PoleVault switcher — The PVS 407D PoleVault switcher functions as an amplifier
for the VoiceLift System. It amplifies the audio signal from the VLR 302 receiver and
sends it to the speakers. The switcher powers speakers placed throughout the room to
improve the signal-to-noise ratio of the voice to at least +15 dB.
