Introduction
About This Guide
This guide covers the installation of the Extron® VoiceLift® Microphone Systems. The
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
knowledge of and experience with audio/video, electrical, or electronic device
installation.
This guide leads the installer through the steps to install and connect each system
component.
The VoiceLift Systems
The VoiceLift Microphone Systems are easy-to-use, low-power, classroom
amplification systems that ensure that 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 a PVS 305SA PoleVault® Switcher, which powers
strategically placed loudspeakers to improve the signal-to-noise ratio of the voice of
the teacher above ambient noise level.
Two VoiceLift systems are available:
 VoiceLift Microphone (VLM) — Consists of one or two pendant microphones,
the IR receiver, and an optional charging station. (This kit can be added to an
existing PoleVault system.)
 VoiceLift Microphone System (VLS) — Consists of the VLM kit components:
one or two pendant microphones, the IR receiver, and an optional charging
station; a PoleVault switcher; and two speakers.
See Inventory, later in this section, for more information on kit contents.
Each VoiceLift Microphone 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 filters
engage, automatically detecting and attenuating unwanted feedback frequencies
up to 30 dB.

Before You Begin — Planning the Installation
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.

not be noticeable, depending on the environment.
VoiceLift Microphone Systems • 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.

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

VoiceLift Microphone Systems • Introduction 5

Reflection
Line of sight from the microphone to the receiver is ideal; however, reflection
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 reflect off
the screen surface to the receiver in the middle of the room. Ideal conditions for
reflection are light colored, smooth surfaces (for example, white drywall). Items to
consider that may affect reflection 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)

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 floor. 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 if over 12 feet (3.6 m) high, consider mounting the receiver
on a pole to reduce the line-of-sight distance to the microphone.

Secondary Receivers (Optional)
If a single receiver is not sufficient for the room, up to three additional secondary
receivers can be added to the system. It is recommended to use as few receivers
as possible in a room, because additional receivers can add noise to the system,
effectively reducing the range of each individual receiver. For example, if one
receiver covers 1600 square feet, two receivers may cover only 1500 square feet
each, for a total of 3000 square feet.
You may need to experiment with placement of each receiver when another one is
added, due to the variable coverage of each receiver.
One or more secondary receivers (VLR 102 SR) may be needed if any of the following
conditions exist:
 The room is larger than 40 feet by 40 feet (12.2 m by 12.2 m).
 Obstructions exist between the microphone and the receiver.
 The room is odd-shaped: L-shaped or long, for example.
 The room has recessed or sheltered areas such as alcoves or bays.
 The room has large windows or windows on multiple walls.
 Portions of the walls are dark or covered.
The diagrams on the next page show examples of secondary receiver placement and
coverage.

Figure 8. Secondary Receiver Coverage
If you want the receiver to cover a large room such as a lecture hall or an
auditorium, consider restricting the coverage to only the area the microphone user
can cover (for example, the front of the room). There is no need to cover the middle
or back of the room if the microphone is not used in that area.
Figure 9. Receiver Placement in a Large Room
When placing a receiver to cover a certain part of the room, you do not need to
angle the receiver in the direction of the target area. The VoiceLift microphone
coverage angle is adequate. If the room has high ceilings, consider mounting the
receiver on poles to reduce the line-of-sight distance.

PoleVault Switcher Location (VLS System Only)
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.
