Audio

Output:

Two

AUDIO

OUTPUT

receptacles

are

located

on

the

rear

of

the

chassis.

They

are

used

to

connect

the

tuner

to

the

amplifier

for

normal

monaural

opera-

tion.

These

two

receptacles

are

electrically

connected

in

parallel.

One

AUDIO

OUTPUT

receptacle

may

connect

to

the

tuner

input

on

your

amplifier,

and

the

other

may

connect

directly

to

your

tape

recorder.

Connecting

for

AM

-FM

Monaural

Operation:

Connect

a

shielded

cable

between

one

of

the

AUDIO

OUTPUT

jacks

and

the

tuner

or

Aux

input

jack

on

your

amplifier.

The

length

of

this

cable may

be

up

to

30

feet.

Connecting

for

FM

Multiplex

Operation:

In

those

localities

where

FM

Multiplex

broadcasting

is

available,

attach

your

multiplex

adapter

to

the

jack

on

the

rear

of

the

TX20

tuner

marked

FM

MULTIPLEX.

The

outputs

of

your

multiplex

adapter

are

then

connected

to

the

left

and

right

channel

tuner

inputs

on

your

stereophonic

amplifier.

This

is

only

one

method

of

FM

multiplexing.

It

is

suggested

you

follow

the

instructions

supplied

with

your

multiplex

adapter

for

proper

hookup

of

your

adapter.

Connecting

the

FM

Antenna:

Due

to

the

extremely

high

FM

sensitivity

of

the

Model

TX20,

the

48"

piece

of

wire

furnished

with

the

set

will

be

sufficient

antenna

for

all

but

the

most

diffi-

cult

locations.

One

end

of

this

wire

should

be

fastened

to

the

"FM"

terminal

of

the

Antenna

Terminal

Strip,

the

other

end

left

free

and

extended

as

may

be

convenient.

It

may

be

tacked

or

stapled

to

the

rear

of

the

bookcase

or

equipment

cabinet

if

necessary.

If,

for

some

reason,

it

is

necessary

to

utilize

a

different

FM

antenna,

we

have

listed

for

your

convenience

the

following

suggestions:

1.

Special

outdoor

FM

antennas

may

be

used.

These

come

in

various

types.

For

extremely

difficult

locations

an

in

-line

Yagi

cut

for

the

FM

band

or

equivalent

may

be

necessary.

For

reception

of

FM

stations

scattered

in

many

directions,

the

non

-directional

antenna

may

be

used.

This

non

-

directional

type

is

known

as

a

double

dipole

and

consists

of

two

folded

dipoles

placed

at

right

angles

to

each

other.

2.

Your

present

TV

antenna

may

be

used

to

obtain

a

maximum

FM

signal.

A

special

antenna

coupler

or

knife

switch

should

be

used

when

joining

the

FM

line

to

the

television

antenna.

Attach

one

lead

of

the

300

ohm

lead-in

wire

to

the

"FM"

terminal

and

the

other

lead

to

the

"G"

terminal.
