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.

Before You Begin — Planning the Installation
Before starting installation, you must consider several major factors to ensure that the installation of the VoiceLift
Microphone 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 Microphone. Because
IR technology requires line-of-sight placement, take into consideration anything that could impact or block the
transmission of the IR signal from the microphone to the receiver.
The lists on the following pages, though not comprehensive, should be consulted to help ensure that key aspects
have been considered.
1. Room layout
The application diagram below shows a typical classroom installation incorporating the VoiceLift Microphone.
Typical classroom installation
N
Due to the operating frequencies of the microphone and receiver, lighting fixtures such as fluorescent lights and
plasma displays should not affect performance of the system.

Room considerations
Room factors to be considered should include, but are not confined to:
• Room conguration
Room size, orientation, and layout
Location of windows, doors, skylights, etc., for potential light interference
Alcoves, bays, or sheltered areas
Location of any dark or covered walls (Dark surfaces reduce reflection of the IR signal.)
– Wall art
– Curtains/blinds
– Acoustical panels
– Wall material/texture
• Line-of-sight obstructions between microphone and receiver
Existing movable furniture (desks, tables, podiums)
Existing installed furniture (bookcases, racks, cabinets, workbenches, sinks, etc.)
Support pillars
Projector
• Ceiling and wall type (important in assessing the installation hardware needed)
Ceiling type (drop, spline, hard lid, etc.); structural type (wood, concrete, trusses)
Wall type (drywall, cement, brick, etc.)
• Receiver location
Best location: on the ceiling, at the middle of the classroom
If ceiling mounting is not possible, place high and centered on the longest wall.
Locations to avoid:
– Places where line of sight could be obstructed; e.g., too close to the projector
– Corners of the room
– On walls, at less than 6' or more than 12' up from the base
– Areas that receive direct sunlight

• Optional VLR 102SR Secondary 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' by 40'.
Obstructions exist between the microphone and the receiver.
The room is odd-shaped, e.g., L-shaped or long.
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 and/or covered. Dark surfaces reduce signal reflection. Take the following into
consideration:
– Wall art
– Curtains/blinds
– Acoustical panels
– Wall material/texture
The following diagrams show examples of secondary receiver placement.

odd-shaped room
Receiver and three secondary receivers in a large room, or a room with
