This

precaution

loads

the

unused

channel

and

prevents

damage

to

the

output

stage

of

the

receiver.

Please

refer

to

B

Speaker

Phasing:

When

more

than

one

speaker

is

used

in

any

music

reproducing

system

they

must

be

connected

in

such

a

way

as

to

aid

each

other,

rather

than

to

work

against

each

other.

Since

two

speakers

must

be

used

for

stereo

reproduction,

this

caution

applies.

Checking

for

phase,

and

correcting

if

necessary,

is

quite

simple,

and

is

done

at

the

time

of

installation

of

the

system.

Play

a

record

with

readily

apparent

bass

tones.

Listen carefully

to

the

strength

and

clarity

of

the

bass.

Now

reverse

the

connections

of

one

of

the

speakers.

If

the

bass

notes

are

now

louder

and

clearer,

the

speakers

are

now

correctly

phased.

If

the

bass

seems

weaker,

the

original

connection

was

correct.

A

IMPORTANT:

When

the

TA224

is

used

only

for

monophonic

operation

(

and

stereo

is

to

be

added

at

some

later

date)

it

is

essential

that

both

speaker

output

terminals

are

terminated

into

speakers

or

into

a

speaker

and

resistive

load.

For

example,

if

you

have

only

one

speaker,

attach

it

to

the

Left

Speaker

Output

connections

and

connect

an

8

or

16

ohm

25

watt

wirewound

resistor

to

the

Right

Speaker

Output

connections.

This

will

assure

proper

loading

of

the

output

stage

and

will

prevent

damage

to

the

output

tubes.

A

more

satisfactory

solution

would

be

to

connect

an

additional

speaker

for

monophonic

listening

instead

of

the

8

or

16

ohm

resistor.

Refer

to

Diagram

B.

Connecting

The

FM

Antenna:

Due

to

the

exceptionally

high

FM

sensitivity

of

the

TA224,

the

48"

piece

of

wire

supplied

with

the

unit

will

be

sufficient

antenna

for

all

but

the

most

difficult

locations.

One

end

of

this

wire

should

be

stripped

of

insulation

and

attached

to

the

rear

screw

terminal

marked

FM

on

the

Antenna

Terminal

strip

located

on

the

rear

of

the

chassis.

The

other

end

of

this

wire

should

be

extended

horizontally

along

the

cabinet

or

table.

Horizontal

placement

of

the

antenna

wire

provides

proper

polarization

for

optimum

reception.

If

an

outdoor

antenna

is

required

to

"reach"

for

distant

stations,

use

a

folded
