This

switch

has

four

positions.

STEREO

NORMAL

enables

the

speakers

to

operate

in

the

manner

in

which

they

are

normally

connected. STEREO

RE-

VERSE

interchanges

the

channels

so

that

the

program

source

appearing

at

the

left

speaker

now

appears

at

the

right

and

the

program

source

appearing

at

the

right

speaker

reverses

to

the

left.

MONAURAL

RIGHT

and

MONAURAL

LEFT

can

he

utilized

when

the

amplifier

is

used

in

stereo

connection,

but

with

a

mon-

aural

program

source

such

as

an

FM

broadcast.

Setting

the

MODE

switch

to

RIGHT

allows

any

program

material

being

fed

into

the

right

stereo

input

to

be

reproduced

by

both

speakers simultaneously.

Setting

the

MODE

switch

to

LEFT

allows

all

program

material

being

fed

into

the

left

stereo

input

to

be

reproduced

by

both

speakers

simultaneously.

Under

each

of

these

conditions

the

combined

power

of

both

channels

is

available.

Function

Switch:

The

FUNCTION

switch

selects

the

desired

type

of

program

source

and

has

four

positions.

TAPE

HD

selects

your

tape

deck

plugged

into

the

TAPE

HD

jacks

located

on

the

rear

panel.

PHONO

selects

the

low

level

stereo

phono

cart-

ridge

plugged

into

the

LOW

LEVEL

PHONO

jacks

or

the

high

level

ceramic

or

crystal

stereo

cartridge

plugged

into

the

HIGH

LEVEL

phono

jacks

located.

on

the

rear

panel.

The

TUNER

position

selects

your

stereo

tuner

for

operation

and

the

AUX

position

selects

your

stereo

tape

recorder

or

other

auxiliary

stereo

equipment.

Speaker

Selector

Switch:

For

stereo

operation,

this

switch

is

inoperative.

Equalization

Switch:

Records

and

tapes

are

recorded

with

special

emphasis

and

deemphasis

of

cer-

tain

frequencies

in

order

to

achieve

maximum

dynamic

range.

To

play

hack

your

records

and

tapes

faithfully,

it

is

necessary

to

"equalize"

their

frequency

response.

When

playing

your

stereophonic

records

set

the

EQUALIZATION

switch

to

the

RIAA

position.

It

is

not

necessary

to

use

the

FUR

position

since

all

stereo-

phonic

recordings

are

recorded

only

with

the

RIAA

equalization

curve.

When

you

are

using

your

tape

deck

through

the

TAPP:

HD

input

jacks,

set

the

EQUALIZATION

switch

to

either

394

or

73

depending

on

the

tape

speed

used.

Proper

playback

equalization

is

then

automatically

selected.

ADDITIONAL

INFORMATION

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,

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

on

one

of

the

speak-

ers.

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.
