About this Guide

This guide provides 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.

• UL listed electrical boxes are recommended.

About the VoiceLift System

The VoiceLift System is a low-power classroom microphone amplification system that ensures that an instructor can be clearly heard at a comfortable level throughout the entire room (also referred to as a “soundfield system”). The pendant or hand-held microphone picks up speech from the instructor or student and transmits it to the receiver via an IR signal. From the receiver, the signal is sent to an Extron PoleVault switcher, which amplifies and powers speakers to improve the signal-to-noise ratio 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 System kit components, a PoleVault switcher, and two speakers.

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

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 filters engage, automatically detecting and attenuating unwanted feedback frequencies up to 30 dB.

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 (see Room Considerations on the next page).

VoiceLift System with PVS 405D Installation Guide • Introduction 3

Room Considerations

The following room factors are important to consider when you are planning the installation of a 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 centimeters) 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 meters) away from windows and skylights. If this is not possible, cover windows and skylights with curtains, blinds, or other covering options.

• 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 centimeters) 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 with PVS 405D 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

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 meters) and

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