OPERATING

PROCEDURE

Every

control

on

this

receiver

serves

a

specific

useful

function

and

is

important

for

the

proper

operation

of

your

stereo

system.

We

recommend

that

you

read

the

following

section

carefully

so

you

may

take

full

advantage

of

the

performance

capabilities

of

your

receiver.

VOLUME

CONTROL

The

VOLUME

control

adjusts

the

signal

level

of

any

program

material

con-

nected

to

your

stereo

receiver.

It

is

a

two

section

control

which

simultaneously

adjusts

both

channels,

and

its

close

tracking

specifications

insure

that

the

relative

volume

level

of

each

channel

will

be

identical.

BALANCE

CONTROL

The

nature

of

stereo

reproduction

is

such

that

it

requires

two

identical

channels

to

attain

the

highest

degree

of

faithfulness

and

spatial

distribution.

Any

variation

in

the

efficiency

of

one

channel

as

compared

to

the

other

will

disturb

this

relationship.

Since

there

may

be

slight

differences

between

the

two

speakers,

the

tape

heads,

etc.,

your

receiver

includes

a

control

to

balance

one

channel

against

the

other.

Sufficient

range

is

covered

by

this

control

to

permit

rebalancing

of

the

overall

system

even

in

cases

where

major

unbalance

exists.

This

control

may

be

set

anywhere

within

its

range

to

attain

system

balance.

It

does

not

necessarily

have

to

be

set

in

the

exact

vertical

position.

When

the

BALANCE

control

is

properly

set,

the

apparent

sound

source

will

lie

in

a

broad

area

between

the

two

speakers.

When

the

BALANCE

control

is

rotated

to

the

right

the

sound

will

move

to

the

right

and

when

the

control

is

rotated

to

the

left,

the

sound

will

move

to

the

left.

BASS

AND

TREBLE

CONTROLS

The

BASS

TREBLE

controls

on

your

provide

the

full

The

tone

control

range

is

considerable

and

can

adequately

adjust

the

low

preference,

speaker

characteristics

and

room

acoustics.

You

may

adjust

both

the

BASS

and

TREBLE

for

each

channel

simultaneously

or

individually.

The

adjusts

the

LEFT

and

the

inner

knob

adjust

the

RIGHT

channel,

In

order

to

adjust

both

channels

turn

either

knob.

In

order

to
