INTRODUCTION

WHAT

IS

A

WIRELESS

MICROPHONE

SYSTEM?

Microphone:

This

is

an

electro-acoustic

transducer

which

responds

to

sound

waves

and

deliver

essentially

equivalent

electrical

waves.

These

electrical

waves

are

sent

to

the

belt

transmitter

or

handheld

unit.

Transmitter:

The

transmitter

generates

and

amplifies

an

RF

(Radio

Frequency)

carrier

signal,

modulates

this

carrier

with

the

microphone

signal,

and

radiates

the

modu-

lated

RF

carrier.

SIGNAL

MICROPHONE

TRANSMITTER

Figu

RF

CARRIER

Receiver:

The

FM

VHF

receiver

is

tuned

to

the

frequency

of

the

transmitter.

The

receiver

picks

up

the

radiated

RF

signal

from

the

transmitter

through

the

antenna

and

converts

the

RF

signal

into

audio

vol-

tages

for

use

with

PA,

Line,

Network,

etc.

The

receiver

frequency

must

be

matched

to

the

transmitter

frequency.

WHAT

FREQUENCY

BAND

DOES

THE

TELEX

SYSTEM

OPERATE

IN?

The

Telex

ENG-4

System

features

dual

channel,

crystal

controlled

transmitters

and

four

channel

receivers

operating

in

the

VHF

Band

between

150-216

MHz.

There

are

10

standard

frequencies

available.

Your

system

operates

on

a

fixed

frequency

which

can

be

computer

selected

to

provide

"interference

free"

operation.

Up

to

seven

systems

can

be

operated

in

a

single

location

simultaneously,

without

intermodulation.

OFTEN

ASKED

QUESTIONS

Question:

Can

more

than

one

microphone

be

used

simultaneously?

ae

Yes,

but

never

on

the

same

fre-

quency.

You

will

need

to

have

different

fre-

quencies

for

every

receiver/transmitter

combination.

All

units

are

factory

set

for

specific

frequencies.

Ohoestion:

Is

the

system

more

sensitive

in

any

one

particular

direction?

Aga

No,

the

transmitter’s

antenna

radiates

equally

in

all

directions,

but

the

sig-

nal

is

attenuated

by

your

body,

walls

or

other

surrounding

objects.

The

receiving

an-

tenna

is

essentially

sensitive

in

all

directions

as

well,

except

when

using

a

directional

an-

tenna.

Kestim:

Can

the

receiver

receive

other

transmissions

when

the

transmitter

is

turned

off?

Ay

Yes

it

can.

The

Telex

ENG-4

sys-

tem

operates

in

VHF

band

between

150-

216

MHz.

However,

it

is

not

susceptible

to

radio

wave

skip,

CB’ers

or

standard

FM

radio

transmissions.

29.

The

frequency

on

which

your

system

operates

can

be

computer

selected

for

least

interference,

but

there

is

no

such

thing

as

a

100%

clear

channel

all

the time,

anywhere

in

the

U.S.A.,

forever!

If

the

system

is

going

to

be

used

in

a

per-

manent

fixed

location,

the

system

should

operate

interference

free

until

such

a

time

or

date

when

someone

else

begins

using

the

same

frequency.

If

the

system

is

going

to

be

moving

among

various

locations,

you

will

inevitably

run

into

occasional

frequency

conflicts.

In

either

case,

when

you’re

not

using

the

wireless

microphone,

turn

the

gain

down

on

your

audio

mixer,

just

as

you

would

a

wired

microphone.

If

a

mixer

control

is

not

avail-

able,

turn

the

receiver

off

when

the

trans-

mitter

is

not

in

use.

This

will

prevent

the

reception

of

undesired

signals.

If

a

mixer

control

is

not

available

and

the

system

must

be

left

on,

the

transmitter

should

be

left

on

to

prevent

the

receiver

from

picking

up

outside

interference.
