OPERATING

THE

knobs

and

15

pushbuttons

controlling

all

the

of

the

Each

of

the

controls

performs

a

different

function;

but

instead

of

discussing

each

control

separately,

we

wi

ll

i

llustrate

how

they

work

together

to

control

the

reproduction

of

sound

through

the

A402.

Find

the

VOLUME

control

and

turn

it

down

(counterclockwise).

"The

A402

uses

special

transient

surge

protection

which

may

delay

sound

output

up

to

ten

seconds,

You

should

now

hear

sound

from

the

disc

through

your

system.

To

increase

or

decrease

the

loudness

of

the

playback,

the

VOLUME

control

may

be

advanced

(clockwise)

or

turned

down

(counter-

clockwise).

The

BALANCE

control

if

turned

counterclockwise

will

shift

the

loudness

to

the

left

speaker

by

atten-

uating

(reducing

the

loudness

of)

the

right

speaker.

When

turned

in

the

other

direction,

it

has

the

opposite

effect.

The

Play

a

stereo

disc

with

strong

bass

passages.

Listen

carefully

to

the

bass.

If

you

don't

think

it

is

as

full

as

it

should

be,

reverse

the

speaker

connections

for

one

speaker.

If

the

bass

response

im-

proves

your

speakers

were

out

of

phase.

If

the

bass

response

is

poorer

reconnect

the

speaker

as

it

originally

was.

The

phasing

test

can

be

done

with

any

program

material

but

disc

recordings

are

the

recommended

method.

Stereo

material

is

suggested

to

make

the

effect

more

obvious.

If

you

do

not

get

sound

at

this

point,

check

the

control

positions

given

above.

Also,

be

sure

the

TAPE

1

and

TAPE

switches

are

in

the

"out"

position.

are

adjusting

If

you

still

get

no

sound,

check

the

back

panel

connections

for

PHONO

then

check

the

turntable

itself.

NOTE:

Whenever

you

check

connections

at

the

back

panel,

always

push

the

POWER

switch

off.

If,

at

average

listening

levels,

you

hear

an

objectionable

(i.e.

easily

audible)

amount

of

hum,

try

disconnecting

the

ground

wire

from

the

turntable

to

the

A402.

Some

turntable/cartridge

com-

binations

actually

produce

less

hum

this

way.

Another

source

of

hum

is

inade-

quate

seating

of

the

phono

signal

cables

in

the

receptacles

of

the

A402.

Check

this

thoroughly.
