Speaker

Connections:

A

unique

method

of

connecting

one

or

two

loud-

speakers

is

incorporated

in

the

Solo

II

in

order

that

you

may

derive

maximum

enjoyment

from

this

superlative

instrument

with

any

of

today's

fi

ne

speaker

systems.

Connecting

one

loudspeaker:

Connect

one

of

the

two

speaker

leads

to

terminal

"G"

and

the

other

lead

to

"A"

on

the

three

screw

terminal

strip

at

the

rear

of

the

chassis

marked

"SPEAKER."

For

speakers

with

an

impedance

of

12

to

24

ohms

place

the

Impedance

Selector

Jumper

located

at

the

rear

of

the

chassis

so

that

the

center

terminal

is

connected

to

the

terminal

marked

16.

For

speakers

with

an

impedance

of

4

to

12

ohms

place

the

Impedance

Se-

lector

Jumper

so

that

the

center

terminal

is

connected

to

the

terminal

marked

8.

The

front

panel

Speaker

Selector

Switch

should

then

be

placed

in

the

"A"

posi-

tion.

CAUTION:

A

jumper

is

connected

between

"A"

and

"B"

ter-

minals

on

the

Speaker

Terminal

Strip

on

the

rear

of

this

instrument.

When

only

one

loudspeaker

is

used,

this

jumper

must

be

connected

at

all

times.

It

should

be

re-

moved

only

when

two

separate

speakers

are

connected.

This

precaution

will

prevent

the

set

from

appearing

to

be

inoperative

when

only

one

speaker

is

connected,

and

the

Speaker

Selector

Switch

is

improperly

set.

Connecting

two

loudspeakers:

If

you

wish

to

operate

two

loudspeakers

with

the

Solo

II

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

disturb

the

overall

response.

To

select

speaker

A,

place

the

front

panel

Speaker

Selector.Switch

in

the

"A"

position.

To

select

speaker

B,

place

the

switch

in

position

"B".

To

activate

both

speakers

simultaneously,

place

the

front

panel

Speaker

Selector

Switch

in

position

marked

"AB".

OPERATION

In

general,

every

control

on

a

well

designed,

hon-

estly

considered

high

fi

delity

instrument

has

a

specific

useful

function,

related

to

each

of

the

other

controls.

Although

this

cannot

be

a

treatise

on

the

subject,

an

explanatory

note

on

the

relationship

of

the

various

front

panel

controls

will

doubtless

prove

useful

in

organizing

and

clarifying

them

for

the

user.

Your

Solo

II

incorporates

the

following

operating

controls

located

on

the

front

panel.

Viewing

the

in-

strument

from

the

front

and

reading

from

left

to

right

you

will

note

the

Scratch

Filter

Control,

Bass

Control,

Treble

Control,

Loudness

(volume)

Control

(on/off

switch

is

incorporated

into

this

control),

Dynamic

Con-

tour

Control

and

Tuning

Control.

In

the

upper

left

hand

corner

you

will

fi

nd

the

Function

Selector

Switch

and

in

the

upper

right

corner

the

Speaker

Selector

Con-

trol.

To

operate,

turn

the

Function

Selector

Switch

to

the

AM

position.

Set

the

Bass

and

Treble

tone

controls

so

that

the

white

lines

on

the

knobs

point

straight

up.

This

will

assure

a

"flat"

uncompensated

response.

Turn

the

set

on

by

rotating

the

Loudness

Control

in

a

clock-

wise

position;

now

set

this

Loudness

Control

at

1/3

volume.

The

Contour

Control

should

remain

on

zero

at

this

time.

Tune

for

an

AM

station.

Once

the

desired

program

is

located

and

tuned

in,

adjust

the

volume

so

that

the

music

is

played

at

a

com-

fortable

level.

Now

adjust

the

Bass

and

Treble

tone

controls

to

correct

for

the

electro-acoustic

characteris-

tics

of

the

loudspeaker

you

are

using

and

the

acoustic

characteristics

of

the

room

in

which

you

are

listening.

Modify

each

control

until

settings

are

chosen

which

in

your

total

system

create

the

proper

sense

of

aural

balance

and

evenness.

Now

reduce

the

Loudness

(Volume)

control

setting

somewhat

lower

than

normal

listening

level

in

your

room.

You

will

note

that

the

full

bodied

lifelike

quality

you

experienced

at

high

listening

level

has

disappeared

(this

because

of

the

Fletcher

-Munson

effect

described

in

the

paragraph

on

the

H/K

Dynamic

Loudness

Con-

tour).

With

all

other

controls

unchanged,

select

the

best

contour

setting

for

you.

Do

this

by

switching

quickly

through

the

several

positions

until

you

fi

nd

the

one

which

most

nearly

duplicates

the

full

bodied

sound

you

enjoyed

at

high

level.

Now

turn

the

Loudness

con-

trol

up

to

the

level

at

which

you

wish

to

listen

(per-

haps

the

maximum

level

you

can

permit

in

your

home).

You'll

fi

nd

that

there

is

automatic

compensation

of

con-

tour

wherever

you

set

the

Loudness

control

thereafter.

In

fact,

under

normal

circumstances

you

should

not

fi

nd

it

necessary

to

readjust

the

tone

controls

or

the

contour

selector

once

having

chosen

the

correct

settings

for

you,

your

room

and

your

system.

TECHNICAL

EXPLANATION

OF

THE

CONTROLS

The

Function

Selector

Switch

has

8

positions:

AUX,

AM,

FM,

FM

-AFC,

RIAA-Rumble,

RIAA,

LP

and

EUR.

Its

use

is

to

select

the

desired

type

of

program.

Listed

below

is

the

explanation

of

the

various

functions.

Automatic

Frequency

Control:

(AFC)

FM

broadcasting,

by

its

very

nature,

eliminates

al-

most

all

natural

and

man-made

static.

However,

the

characteristics

of

FM

which

makes

this

possible

also

causes

problems

in

tuning.

The

Solo

II

incorporates

a

special

electronic

circuit

known

as

Automatic

Frequency

Control

that

overcomes

these

problems

and

insures

proper

tuning

even

if

the

manual

tuning

is

not

accurately
