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

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 conguration

 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

Introduction — Planning, cont’d

• 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.
