Introduction

This guide covers the installation of the Extron

VoiceLift VLR 102 receiver can be installed on a drop ceiling, a standard junction

box, an octagonal ceiling box, or a wall. It is assumed that the installer has some

The VoiceLift Microphone Systems are easy-to-use, low-power, classroom

amplification systems that ensure that the teacher can be clearly heard at a

strategically placed loudspeakers to improve the signal-to-noise ratio of the voice of

the teacher above ambient noise level.

See Inventory, later in this section, for more information on kit contents.

Each VoiceLift Microphone System contains a feedback suppressor (FBS) that

engage, automatically detecting and attenuating unwanted feedback frequencies

up to 30 dB.
