can

be

improved

by

the

addition

of

rugs

and

heavy

draperies,

which

also

serve

to

eliminate

echoes

and

standing

waves.

For

acous-

tically

"dead"

rooms

(e.g..

those

with

wall-to-wall

carpets,

heavily

upholstered

furniture,

large

amounts

of

draperies),

furnishings

should

be

arranged

so

that

speakers

have

unobstructed

sound

transmission

paths

to

the

listening

areas.

Finally,

since

no

room

is

acoustically

perfect,

you

are

encouraged

to

use

your

amplifier

or

receiver

tone

controls

to

adjust

the

sound

for

your

maximum

listening

enjoyment.

IN

CASE

OF

DIFFICULTY

If

you

suspect

a

problem

with

one

of

your

Model

301

speakers,

it

is

worth

a

few

minutes

of

your

time

to

determine

whether

the

de-

fect

is

in

your

speaker

or

in

some

other

portion

of

your

high

fidelity

system.

IF

ONE

SPEAKER

SOUNDS

DEFECTIVE,

first

disconnect

the

speaker

that

is

operating

properly

by

disconnecting

the

wire

from

the

output

terminals

on

the

rear

of

the

amplifier.

Next,

disconnect

the

wire

running

to

the

speaker

which

sounds

de-

fective

and

connect

it

to

the

output

terminals

of

the

amplifier

channel

which

you

are

sure

is

operating

properly.

If

the

speaker

now

seems

to

be

operating

properly,

the

defect

is

in

another

part

of

your

hi-fi

.

system.

IF

THE

TROUBLE

APPEARS

IN

BOTH

CHANNELS,

connect

your

Model

301s

to

another

amplifying

source

or

high

fidelity

system

that

is

operating

properly.

If

the

trouble

is

no

longer

apparent,

the

difficulty

is

not

with

the

speakers.
