STEREOPHONIC

POWER

AMPLIFIER

INSTALLATION

PROCEDURE

Ventilation:

The

unit

is

well

ventilated

in

itself,

but

sufficient

space

must

be

allowed

around

it

to

permit

proper

air

fl

ow.

Install

the

amplifier

in

a

manner

to

allow

for

unrestricted

circulation.

Do

not

place

objects

on

the

cage

or

in

the

immediate

vicinity

of

the

instrument.

Reducing

the

air

fl

ow

will

result

in

sharply

reduced

component

and

tube

life.

Power

Requirements:

•

Plug

the

AC

line

cord

(117

volts,

50

or

60

cycles)

into

the

convenience

AC

on

Connecting

Your

Speakers:

Your

two speakers

should

be

matched

if

possible

to

obtain

optimum

results

and

should

be

placed

approximately

8

to

15

feet

apart

against

one

wall

of

your

listening

room.

Corner

placement

is

also

quite

acceptable.

Facing

the

speakers

straight

out

or

slanting

them

slightly

will

depend

on

your

room

size,

acoustic

effect

and

where

you

will

be

seated

for

listening.

It

may

be

necessary

to

experi-

ment

with

speaker

placement

until

best

results

are

obtained.

Use

any

type

wire

to

connect

your

speakers.

Lamp

cord

is

excellent

and

may

be

easily

dressed

around

the

molding

for

an

inconspicuous

and

neat

installation.

Normal

Stereo

Speaker

Arrangement:

Connect

one

lead

from

the

left

speaker

to

the

16

ohm

terminal

on

the

LEFT

SPEAKER

OUTPUT

STRIP

and

the

other

lead

to

the

G

terminal

on

the

same

strip.

Now

connect

one

of

the

leads

from

the

right

speaker

to

the

16

ohm

term-

inal

on

the

RIGHT

SPEAKER

OUTPUT

STRIP

and

the

other

lead

to

the

G

terminal

on

the

same

strip.

(See

Diagram

A)

The

output

terminals

used

should

be

those

marked

with

the

same

impedance

as

the

speakers.

The

illustration

is

for

16

ohm

speakers.

If

you

are

using

8

ohm

speakers

connect

to

the

8

ohm

SPEAKER

output

terminals

rather

than

to

the

16

ohm

terminals.

NOTE:

For

this

method

of

operation

the

PARALLEL

-SEPARATE

switch

must

remain

in

the

SEPARATE

position.
