FM

ANTENNA

A

short

length

of

ordinary

wire,

connected

to

the

terminal

marked

FM

will

prove

adequate

in

most

in-

stallations.

A

loop

of

wire,

approximately

36

inches

long,

connected

between

"FM"

and

"G"

and

hung

inside

the

cabinet

will

prove

useful

in

increasing

the

rejection

of

spurious

signals.

In

those

situations

requiring

an

external

FM

antenna,

connections

should

be

made

be-

tween

"G"

and

"FM."

A

single

dipole

will

be

useful

when

stations

to

be

received

are

located

in

opposite

directions

from

each

other.

A

non

-directional

dipole

should

be

used

if

the

stations

are

located

in

dispersed

directions.

A

folded

dipole

antenna

with

reflector

will

provide

maximum

efficiency

and

may

increase

the

num-

ber

of

distant

FM

stations

your

TA

-10

can

receive.

POWER

Plug

the

power

cord

into

any

outlet

furnishing

117

volts,

60

cycles

house

current.

The

exact

voltage

is

relatively

unimportant,

and

may

vary

between

105

and

125.

Be

sure,

however,

that

you

have

60

cycle

AC

power.

A

convenience

outlet

at

the

rear

of

the

Solo

may

be

used

for

your

record

player

which

will

then

be

turned

on

or

off

by

the

Solo

power

switch.

PHONOGRAPH

CONNECTIONS

Any

type

of

record

player

will

operate

with

the

Solo.

To

derive

maximum

enjoyment

it

is

suggested

that

a

high

quality

pickup

cartridge

and

a

rumble

-free

turn-

table

be

used.

Two

classes

of

pickup

cartridges

are

in

general

use:

Magnetic

(GE,

Pickering,

Fairchild,

and

Audak)

and

Crystal

(including

the

newly

developed

ce-

ramics).

While

any

type

of

cartridge

may

be

used

with

the

Solo,

it

is

strongly

urged

that

the

magnetic

type

be

selected.

It

should

be

plugged

into

the

receptacle

marked

"PHONO."

Connect

crystal

or

ceramic

cartridges

to

the

receptacle

marked

"AUX.

"

A

word

of

advice:

The

useful

life

of

a

phonograph

needle

is

quite

short,

ranging

from

15

minutes

to

sev-

eral

hours.

In

addition

to

degradation

of

tone

quality

as

the

needle

wears,

the

strong

possibility

exists

that

valuable

records

will

be

damaged

if

worn

needles

are

not

promptly

replaced.

The

purchase

of

a

diamond,

which

has

extremely

long

life,

is

therefore

a

worth-

while

investment.

The

power

cord

of

the

turntable

may

be

plugged

into

the

auxiliary

AC

power

outlet

on

the

rear

of

the

Solo.

It

is

sometimes

advisable

to

ground

the

phonograph

chassis

to

the

receiver,

to

reduce

hum

or

other

unwanted

noises.

This

may

be

accomplished

by

the

use

of

any

type

of

wire,

one

end

connected

to

the

"G"

terminal

of

the

"ANTENNA"

or

"SPEAKER"

terminal

strips,

the

other

end

connected

to

the

metal

framework

of

the

phono-

graph.

AUXILIARY

INPUT

An

extra

input

is

provided

for

auxiliary

high

level

equipment

such

as

a

tape

recorder

or

television

tuner.

This

input

is

located

on

the

rear

of

the

Solo

chassis.

If

2

you

are

using

a

ceramic

or

crystal

cartridge

make

cer-

tain

to

connect

your

phonograph

output

to

this

input.

TAPE

OUTPUT

A

receptacle

marked

"Tape

Out"

is

located

on

the

rear

of

the

chassis.

This

is

used

to

provide

output

to

a

tape

recorder

or

other

auxiliary

equipment.

Any

program

material

appearing

at

the

speaker

terminals

also

appears

at

the

"Tape

Out"

receptacle,

but

unmod-

ified

by

the

volume

or

tone

controls.

This

makes

it

possible

to

record

programs

with

the

proper

recording

equalization

(as

determined

by

your

tape

recorder)

while

simultaneously

listening

to

the

program

with

the

proper

tone

control,

contour

and

loudness

settings.

SPEAKER

CONNECTIONS

A

unique

method

of

connecting

one

or

two

loud-

speakers

is

incorporated

in

the

Solo

in

order

that

you

derive

maximum

enjoyment

from

this

superlative

in-

strument

with

any

of

today's

fine

speaker

systems.

For

those

using

one

speaker

connect

the

speaker

leads

to

terminals

"G"

and

"A"

on

the

three

screw

ter-

minal

strip

at

the

rear

of

the

chassis

marked

"SPEAK-

ER.

"

For

speakers

with

an

impedance

of

12

to

24

ohms

place

the

Impedance

Selector

Switch

located

at

the

rear

of

the

chassis

in

position

1.

For

speakers

with

an

im-

pedance

of

from

4

to

12

ohms

place

the

Impedance

Se-

lector

Switch

in

position

2.

The

front

panel

Speaker

Selector

Switch

should

then

be

placed

in

position

"A."

If

you

wish

to

feed

two

speakers

with

the

Solo

and

use

either

one

or

both

together

connect

the

second

speaker

to

terminals

"G"

and

"B"

on

the

speaker

terminal

strip.

For

best

operation

both

speakers

should

have

the

same

impedance,

although

a

slight

mismatch

will

not

affect

the

overall

response.

To

select

speaker

A

slide

the

front

panel

Speaker

Selector

Switch

to

position

"A."

To

select

speaker

B

slide

the

switch

to

position

"B."

To

feed

both

speakers

at

the

same

time

slide

the

switch

to

the

position

marked

"AB."

Due

to

the

fact

that

the

Speaker

Selector

Switch

changes

the

transformer

con-

nections

as

well

as

the

speaker

connections

in

any

posi-

tion

either

or

both

speakers

will

be

fed

at

the

correct

matching

impedance

and

optimum

results

will

be

ob-

tained.

AUTOMATIC

FREQUENCY

CONTROL

(AFC)

FM

Broadcasting,

by

its

very

nature,

eliminates

almost

all

natural

and

man-made

static.

However,

the

characteristics

of

FM

which

make

this

possible

also

make

for

problems

in

tuning.

The

HARMAN-KARDON

Solo

incorporates

an

effective

Automatic

Frequency

Con-

trol

(AFC)

circuit

that

overcomes

these

problems

and

insures

proper

tuning

even

if

the

manual

tuning

is

not

accurately

done.

The

following

experiment

will

lead

to

an

understanding

of

AFC,

and

the

fuller

enjoyment

of

the

Solo.

Tune

across

the

FM

scale

with

the

function

switch

into

the

FM

-AFC

position.

Note

how

the

stations
