Functional Overview of the VoiceLift Microphone

The VoiceLift Microphone is a soundeld system, which is a low-power classroom

amplification system that ensures that the teacher can be clearly heard at a
comfortable level throughout the classroom.

The pendant microphone, worn by the teacher/speaker, picks up speech and
transmits it via IR signal to the receiver. From the receiver, the signal is fed to

a PoleVault switcher/amplier, which powers strategically placed speakers to
improve the signal-to-noise ratio of the teacher’s voice to at least +15 dB.

Audio signal transission

The VoiceLift Microphone components process an audio signal as follows:

PRELIMINARY

VoiceLift Microphone connections and signal path

Pendant microphone — The VLP 102 pendant microphone picks up speech

a

from the instructor and transmits a mono audio signal via IR on the selected

channel (2.3 MHz or 2.8 MHz).

2-2

VoiceLift™ Microphone • Operation and Features

Wall charger

1

Receivers — The VLR 102 receiver and the optional VLR 102 secondary

b

receiver(s) pick up the IR signal from the microphone. If secondary receivers

are present, the VLR 102 processes the signal from them.

The receivers output a balanced -10 dBV line level signal via an RJ-45
connector. The signal is passed to the PoleVault switcher/amplier through
an unshielded twisted pair (UTP) cable.

Adapter — The RJ-45 to captive screw VoiceLift Adapter passes the audio

c

signal from the VLR 102 receiver to the PoleVault switcher.

PoleVault switcher — The PoleVault switcher also functions as an amplier

d

for the VoiceLift Microphone. It receives the audio signal from the VLR 102

receiver, amplifies it, and sends it to strategically placed loudspeakers to

improve the signal-to-noise ratio of the teacher’s voice to at least +15 dB.

Cable lengths

The following table shows the recommended minimum and maximum lengths of
cable between system components.

Commands and Responses

Command/response Table for SIS Commands

PRELIMINARY

SIS™ Conguration and Control

The VoiceLift VLR 102 receiver can be controlled via a host computer that is
connected to the receiver’s RS-232 control port. You can issue Extron’s Simple
Instruction Set (SIS™) commands using the computer’s RS-232 interface with a

communication software program such as HyperTerminal or Extron’s DataViewer.

SIS commands are available for you to do the following:

• Upload rmware

• Obtain information and status for VoiceLift ports and system components

• Adjust the volume for a specific channel

Protocol for the VoiceLift receiver’s RS-232 port is:

• 38400 baud

• 8 data bits

• 1 stop bit

• no parity

• no ow control

Host-to-Receiver Communications

SIS commands consist of one or more characters per field. No special characters

are required to begin or end a command sequence. When the VLR 102 determines

that a command is valid, it executes the command and sends a response to the host
device. All responses from the receiver to the host end with a carriage return and
a line feed (CR/LF = ]), which signals the end of the response character string.
A string is one or more characters.

PRELIMINARY

Receiver-initiated messages

When a local event such as a volume adjustment takes place, the VLR 102 responds

by sending a message to the host. No response is required from the host. The
receiver-initiated messages are listed below (underlined).

Setting Up an Instant Alert

A useful application for the VoiceLift Microphone is the instant alert. By connecting
an MLC 104 IP Plus control panel to the VLR 102 receiver’s relay port, you can set

up e-mail alerts to be sent out when both parts of the microphone’s Volume button
are pressed and held for 3 seconds.

To set up an instant alert, follow these steps:

1. Wire one of the provided two-pole captive screw connectors to one end of a

communication cable.

Insert the red wire in the connector’s left slot and the black wire in the right

slot.

2. Plug the communication cable into the receiver’s Rly (relay) port. Ensure that

the red wire is connected to the NO (normally open) port and the black wire is
in the C (common) port.

PRELIMINARY

N

If the MLC and the PoleVault switcher are using separate power supplies,

ground the receiver’s Rly port C pin to the receiver using a jumper between the
C pin and the ground (_) pin on the contact input (CTC), the auxiliary input
(Aux In), or the RS-232 port.

This section provides an overview of the procedures for planning and performing

an installation of the VoiceLift VLR 102 Receiver and/or the VLR 102 SR Secondary

Receiver. For the complete procedures, refer to the VoiceLift Microphone Installation
Guide, part #68-1629-01.

Planning the Installation

Before you start to install the VLR 102 receiver, there are several major factors that
you must consider in order to ensure that the installation is as smooth and trouble
free as possible, and that the result meets the needs of the users.

Placeent of the receiver

Placement of the receiver (sensor location) is very important for optimal
performance of the microphone. The best location is in the ceiling, at or near the
middle of the room, where the receiver is in line of sight, regardless of the teacher/
presenter’s position in the room. This also minimizes the transmission distance.
If mounting on the ceiling is not possible, the receiver should be placed high and
centered on the longest wall of the room.

Roo layout and content considerations

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. If obstruction is unavoidable, the IR signals can
bounce off walls and still reach the sensor; however, light-absorbing surfaces such
as dark walls or chalkboards also can impede the signal.

The diagram below shows a typical classroom installation incorporating the

VoiceLift Microphone.

Locations

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

• Room conguration

• Line-of-sight obstructions between microphone and receiver

• Ceiling and wall type (important in assessing the installation hardware

needed)

• Location of the VLR 102 receiver

 Best location is on the ceiling, at the middle of the classroom.
 If ceiling mounting is not possible, place high and centered on the longest

wall.

Example of a classroom installation

 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

• Need for optional VLR 102 SR secondary receiver

One or more secondary receivers (VLR 102 SR) may be needed if:

 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 reection.
