Your

two

speakers

should

be

identical,

if

possible,

to

obtain

optimum

results.

Experts

agree

that

a

perfectly

matched

system

offers

the

best

stereophonic

repro-

duction,

The

speakers

should

be

placed

along

the

same

wall

approximately

8

to

10

feet

apart

depending

upon

room

size

and

furniture

placement.

It

may

be

necessary

to

experiment

with

speaker

placement

until

best

results

are

obtained.

Use

any

type

of

wire

to

connect

your

speakers

to

the

SR900.

Lamp

cord

"zip

cord"

is

excellent

and

may

be

easily

dressed

around

the

molding

for

an

inconspicuous

and

neat

installation.

Do

not

drive

the

staples

or

tacks

through

the

center

of

the

wire

for

this

may

short

out

the

two

sections

and

will

decrease

the

or

short

out

the

speakers

entirely.

It

is

permissible

to

use

1.

Connect

Your

receiver

is

now

connected

for

1

system

stereo

operation

and

is

opera-

tive

when

the

speaker

selector

switch

on

the

front

panel

is

in

the

System

1

or

System

1

&

position.

SPEAKER

PHASING

When

more

than

one

speaker

is

used

in

any

music

reproducing

system

the

speakers

must

be

connected

in

a

manner

to

work

together

rather

than

work

out

of

phase.

If

one

speaker

is

pushing

air

out

while

the

other

is

moving

in

the

opposite

•

direction

this

will

result

in

diminishing

bass

response.

Checking

for

proper

phase

and

correcting

if

necessary

is

quite

simple.

1.

Place

a

stereophonic

recording

on

your

record

player.

2.

Pull

the

"Stereo

-Mono"

switch

on

the

BALANCE

control

to

its

"Out"

position

for

monophonic

playback.

3.

Play

the

record.

The

sound

should

emerge

from

approximately

the

center

area

between

the

two

speakers.

4.

While

the

record

is

playing

push

the

"Stereo

-Mono"

switch

"In"

to

the

stereophonic

position.

5.

The

sound

should

now

move

across

the

wall

of

the

room

and

should

appear

to

come

from

both

speakers

as

well

as

the

center.

6.

If

your

speakers

are

out

of

phase,

the

sound

source

will

not

pinpoint

itself

between

the

two

speakers

when

the

Stereo

-Mono

switch

is

in

the

monophonic

position.

Instead

it

will

appear

to

come

from

both

sides.

If

the

speakers

are

out

of

phase,

turn

off

the

receiver

and

disconnect

both

leads

from

either

the

left

or

right

speaker

and

reverse

them.

Your

system

will

now

be

in

phase.

This

completes

your

speaker

connections.

The

SR900

is

a

solid

state

device

which

does

not

contain

audio

output

transformers,

It

is

therefore

not

necessary

to

match

the

impedance

of

your

speakers

to

the

receiver.

The

SR900

will

per-

form

perfectly

with

any

speaker

which

has

an

impedance

of

4,

8

or

16

ohms.
