About This Guide

This manual covers the installation of the Extron VoiceLift™ Microphone as part of an Extron PoleVault™ system. The VoiceLift VLR 102 receiver can be installed in a drop ceiling, a standard junction box, an octagonal ceiling box, or on a wall. It is assumed that the installer has some knowledge of and experience with A/V, electrical, or electronic device installation. This manual guides the A/V installer through the steps to install and connect each component of the system.

The VoiceLift Microphone

The Extron VoiceLift Microphone is an easy-to-use, low-power, classroom amplification system that ensures the teacher can be clearly heard at a comfortable level throughout the classroom. Speech is picked up by the pendant microphone worn by the teacher and is transmitted wirelessly to a base station receiver. The signal is then fed to the PVS 204SA PoleVault Switcher, which powers strategically placed loudspeakers to improve the signal-to-noise ratio of the teacher's voice above ambient noise level.
