About this Guide

This guide leads the installer through the steps to install and connect each component
of the Extron VoiceLift System. The VoiceLift VLR 102 receiver can be installed in a
drop ceiling, a standard junction box, an octagonal ceiling box, or a wall. It is assumed
that the installer has some knowledge of and experience with audio/video, electrical, or
electronic device installation.

ATTENTION:

• Installation and service must be performed by authorized personnel only.

• L’installation et l’entretien doivent être effectués par le personnel autorisé

uniquement.

• UL listed electrical boxes are recommended.

• Extron recommande d’installer le VLR 102 dans un boîtier d’encastrement

électrique mis à la terre, listé UL.

About the VoiceLift System

The VoiceLift System is a low-power classroom microphone amplication system that
ensures that a teacher can be clearly heard at a comfortable level throughout the entire
room (also referred to as a “soundeld system”). The pendant or hand-held 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, which functions as an
amplier and powers strategically placed speakers to improve the signal-to-noise ratio
of the voice of the speaker to at least +15 dB.

Two types of VoiceLift system are available:

• VLM System — Consists of one or two pendant microphones or one pendant and

one handheld microphone, the IR receiver, and an optional charging station. (This kit
can be added to an existing PoleVault system.)

• VLS System — Consists of the VLM kit components, a PoleVault switcher, and two

speakers.

See Inventory beginning on page 9 for more information on kit contents.

VoiceLift System Installation Guide • Introduction 1

Each VoiceLift system contains a feedback suppressor (FBS) that eliminates feedback
caused by high microphone levels, room resonance, or proximity of the microphone
to the speakers. If feedback occurs, up to 15 dynamic lters engage, automatically
detecting and attenuating unwanted feedback frequencies up to 30 dB.

VoiceLift System Installation Guide • Introduction

Before You Begin — Planning the Installation

Receiver

Before you begin the installation, consider the major factors discussed in the following
sections to ensure that the installation of the VoiceLift System is as smooth and trouble
free as possible and that the result meets the needs of the users. Placement of the
receiver (sensor location) is very important for optimal performance of the VoiceLift
System. Because IR technology requires line-of-sight placement, take into consideration
anything that could affect or block the transmission of the IR signal from the microphone
to the receiver.

noticeable, depending on the environment.

VoiceLift System Installation Guide • Introduction 3

Room Considerations

The following room factors are important to consider when you are planning the
installation of your VoiceLift system:

Interference and noise sources

Infrared and radio frequency noise can reduce the performance of the microphone
system. To minimize noise in the system, avoid mounting the VoiceLift receiver near the
following items:

• Lighting, fluorescent or incandescent — Keep the receiver at least 2 feet

(61 cm) away from a light source. Do not place the receiver where light can shine
directly into it.

• Sunlight — Place the receiver at least 6 feet (1.8 m) away from windows and

skylights. If this is not possible, cover windows and skylights with curtains, blinds, or
other covering.

• Plasma displays — Do not have plasma displays in the room with the microphone

system.

• Electrical equipment — Take placement of electrical equipment such as power

lines or supplies, projectors, dimmers, and computers into consideration, as these
could interfere with the IR signal.

• Cellular phones — Keep cell phones at least 2 feet (61 cm) away from both the

receiver and the microphone.

• Other IR devices — Take placement of other IR devices such as assistive listening

devices or IR remote controls into consideration, as these could interfere with the IR
signal.

VoiceLift System Installation Guide • Introduction

Line-of-sight obstructions between microphone and receiver

A clear line of sight between the microphone and the receiver is critical for best
performance. Take the following potential obstructions to the IR signal into consideration
when placing the receiver:

• Movable furniture (such as desks, tables, and podiums)

• Installed furniture (such as bookcases, racks, cabinets, workbenches, and sinks)

• Support pillars

• I-beams

• Projectors

Figure 5. Potential Line-of-Sight Obstructions

VoiceLift System Installation Guide • Introduction 5

Reflection

Line of sight from the microphone to the receiver is ideal; however, reection of the IR
signal also plays a part in the coverage for most rooms. For example, if the speaker with
the microphone is facing a screen, the IR signal may reect off the screen surface to
the receiver in the middle of the room. Ideal conditions for reection are light colored,
smooth surfaces (for example, white drywall). Items to consider that may affect reection
include:

• Ceiling type (such as drop, spline, or hard lid)

• Wall type (such as drywall, cement, acoustical panel, or brick)

• Wall coverings (such as wall art, hangings, or dark colored paint)

• Curtains and blinds

• Furniture (such as bookcases or easels)

VoiceLift System Installation Guide • Introduction

Receiver Location

The best location to mount the receiver is on the ceiling in the center of the classroom.
If the receiver is wall-mounted, center it on the wall between 6 feet (1.8 m) and 12 feet
(3.6 m) from the oor. These locations maximize the coverage and line of sight to the
microphone.

Avoid the corners of the room, alcoves, bays, or sheltered areas that can restrict
coverage. If the ceiling is over 12 feet (3.6 m) high, consider mounting the receiver on a
pole to reduce the line-of-sight distance to the microphone.

The PoleVault switcher can be mounted anywhere in the room, because the volume
controls are on the microphone. However, placing the switcher near the ceiling makes
cabling and upgrading to a full PoleVault system easier.

WARNING: Structural ceiling failure could cause serious injury or death. Check the

structural ceiling to ensure that it can handle a load four times the weight of the
nal setup.

AVERTISSEMENT : Un défaut dans la structure du plafond pourrait provoquer
