SPEAKER

PHASING

When

more

than

one

speaker

is

used

in

a

music

reproducing

sys-

tem,

the

speakers

must

he

con-

nected

in

a

manner

which

will

allow

them

to

work

together.

Both

left

and

right

speakers

must

oper-

ate

in

perfect

unison,

moving

back

and

forth

together.

If

the

speakers

are

moving

in

opposite

directions,

the

result

will

be

diminished

bass

response

and

decreased

realism

of

sound.

When

this

occurs,

the

speakers

are

said

to

be

out

of

phase.

The

use

of

plug

in

receptacles

on

both

your

Music

System

and

your

speakers

insure

that

your

system

wi

ll

always

be

in

phase.

If

you

connect

a

second

pair

of

speakers

to

your

system

which

use

screw

terminals

instead

of

plug

in

connections,

you

may

check

if

they

are

properly

phased.

If

cor-

rection

is

required

it

•

is

quite

simple.

-

I.

Place

the

FUNCTION

switch

in

the

MONO

FM

position.

2.

Select

an

FM

broadcast

which

has

a

single

speaking

or

singing

voice,

or

a

solo

instrument.

3.

The

voice

or

instrument

should

appear

to

be

coming

from

an

area

directly

between

the

two

speakers.

If

the

speakers

are

out

of

phase,

the

sound

will

appear

to

be

coming

from

the

two

individual

speakers.

4.

If

you

determine

that

the

speakers

are

out

of

phase,

sim-

ply

disconnect

the

leads

from

only

one

of

the

speakers

and

reverse

them.

The

system

will

then

be

in

phase.

SPEAKER

PLACEMENT

In

order

to

achieve

the

best

stereo

performance,

proper

speaker

posi-

tioning

is

important.

The

room

diagrams

will

give

you

some

idea

of

where

the

speakers

should

be

placed

with

relation

to

the

main

seating

area.

The

speakers

should

be

off

the

floor

3

or

4

feet

if

pos-

sible

and

approximately

9

feet

apart.

Since

all

rooms

are

different

in

size

or

shape

a

little

experiment-

ing

with

placement

wi

ll

be

worth-

whi

le.

You

will

notice

that

rooms

2

and

3

have

alternate

suggested

positions.

As

a

general

guide

you

should

be

seated

opposite

the

speakers

for

maximum

spacious-

ness

and

concert

hall

effect.

There

should

never

be

the

impression

of

two

separated

sound

sources,

ROOM

3

ROOM

2

neither

should

the

speakers

be

so

close

to

each

other

that

you

never

experience

the

depth

and

separa-

tion

of

stereo.

If

you

should

re-

quire

further

help

in

solving

a

specific

unusual

room

problem

please

write

and

include

a

simple

drawing

of

your

room

layout

and

it's

dimensions

and

we

will

advise

you

of

the

best

location

for

your

speakers.
