When

you

desire

to

play

a

monophonic

record

utilizing

your

stereo

cartridge,

the

MODE

switch

should,

be

set

to

the

MONOPHONIC

position.

This

position

combines

the

left

and

right

sections

of

the

stereophonic

cartridge

and

cancels

vertical

rumble

and

distortion.

Setting

the

MODE

switch

to

RIGHT

when

the

Stereo

Recital

is

set

for

stereo

reproduction

allows

any

program

material

being

fed

into

the

right

input

receptacles

to

be

reproduced

by

both

speakers

simultaneously.

If

you

are

listening

to

a

stereo

the

MODE

switch

to

LEFT

allows

all

program

material

by

both

speakers

simultaneously.

When

using

monophonic

cartridge

with

the

TA224,

the

MODE

must

be

properly

set

to

correspond

with

the

input

used.

If

your

monophonic

cartridge

is

connected

to

the

LEFT

PHONO

LO

input,

then

the

MODE

switch

must

be

set

to

the

LEFT

position

to

activate

the

left

preamplifier.

Similarly

if

your

monophonic

magnetic

cartridge

is

connected

to

the

RIGHT

PHONO

LO

in-

put,

the

MODE

switch

must

be

set

to

the

RIGHT

position

to

activate

the

right

preamplifier.

Tuner

Selector

Switch:

This

switch

selects

the

tuner

portion

of

the

receiver

for

operation.

It

will

not

unless

the

FUNCTION

the

"TUNER"

position.

selects

the

the

FM

the

addition

of

automatic

control.

The

operation

of

this

circuit

will

be

discussed

in

a

later

paragraph.

AM

-FM

selects

both

AM

and

FM

tuners

for

simulcast

stereo

reception.

AM

selects

the

AM

tunner

for

operation.

Turn

the

TUNER

SELECTOR

to

"OFF"

when

the

tuner

is

not

in

use.

FM

-AFC:

FM

broadcasting,

by

its

very

nature,

eliminates

almost

all

natural

and

man-

made

static.

However,

the

characteristics

of

FM

which

makes

this

possible

also

causes

problems

in

tuning.

The

TA224

incorporates

a

special

electronic

circuit

known

as Automatic

Frequency

Control

that

overcomes

these

problems

and

in-

sures

proper

tuning

even

if

the

manual

tuning

is

not

accurately

done.

Therefore

AFC

always

keeps

the

station

in

the

center

of

the

channel

and

eliminates

distor-

tion

caused

by

inaccurate

tuning.
