Introduction — Overview  
FCC Class B Notice  
This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to  
part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference  
in a residential installation. This equipment generates, uses and can radiate radio frequency energy and, if not  
installed and used in accordance with the instructions, may cause harmful interference to radio communications.  
However, there is no guarantee that the interference will not occur in a particular installation. If this equipment  
does cause harmful interference to radio or television reception, which can be determined by turning the  
equipment off and on, the user is encouraged to try to correct the interference by one or more of the following  
measures:  
Reorient or relocate the receiving antenna.  
Increase the separation between the equipment and receiver.  
Connect the equipment into an outlet on a circuit different from that to which the receiver is connected.  
Consult the dealer or an experienced radio/TV technician for help.  
About This Guide  
This manual covers the installation of the Extron VoiceLiftMicrophone as part of an Extron PoleVaultsystem.  
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.

Introduction — Planning  
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.

Room considerations  
Room factors to be considered should include, but are not confined to:  
Room configuration  
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.

Optional Installation Example — Instant Alert  
Installation Example — Setting Up an Instant Alert  
The following pages describe an example of an optional instant alert setup, in which the relay port of the VLR 102  
is connected to a digital I/O port of an Extron MLC 104 IP Plus. This enables e-mail alerts to be sent out when both  
Volume buttons of the VLP 102 microphone are pressed and held for 3 seconds.  
1. Connect the receiver to the  
MLC 104 IP Plus.  
a. Wire one of the provided two-pole captive screw  
connectors to one end of a communication cable.  
b. Plug the communication cable into the receiver’s RLY  
port.  
If the MLC controller and the PoleVault switcher  
are using separate power supplies, ground the  
Relay port common pin to the receiver using a  
jumper between the common pin and the ground  
pin on either the Contact input, the Aux Input, or  
the RS-232 port.  
N
Connect a communication cable to the  
VLR 102 RLY port.  
Å
For separate power supplies, jumper-  
connect the C pin of the Rly port to the  
ground pin of the CTC, Aux In, or RS-232  
port.  
c. Pull the communication cable to the MLC 104 IP Plus  
location.  
d. Connect the other end of the cable to a direct-insertion  
Digital I/O port on the MLC:  
Insert the black wire into the Ground port.  
Insert the red wire into the first available Digital I/O  
port.  
Connect the communication cable to  
an MLC Digital I/O port.

2. Configure the MLC 104 IP Plus.  
a. Using Global Configurator, configure the MLC’s  
Digital I/O port for digital input with pull-up.  
Configure the MLCs Digital I/O port for  
digital input with pull-up.  
Ç
b. Configure a monitor to send an e-mail when the  
Digital I/O port closes.  
Refer to the Global Configurator help file for  
N
MLC configuration instructions.  
3.Test the instant alert notification.  
a. Ensure that the MLC 104 IP Plus is connected to the  
network.  
b. Press and hold the two Volume buttons on the  
microphone simultaneously for 2 seconds. The  
receiver’s LED blinks alternating amber and green.  
Make sure that the microphone is on either  
N
channel A or channel B.  
Press and hold both  
volume buttons  
simultaneously.  
Press and hold both Volume buttons  
for 2 seconds.
