Systems

Connecting

Speakers

to

the

A-401:

Find

the

row

of

four

connectors

on

the

back

panel

of

the

A-401

marked

SPEAKER

SYSTEM

1.

Starting

with

either

Left

or

Right

pair

of

connectors,

push

firmly

in

on

the

plastic

head

of

each

con-

nector,

revealing

an

opening.

Insert

each

of

the

bare

conductors

at

the

end

of

one

of

the

lengths

of

wire

you've

prepared

into

the

opening.

Release

the

connector.

Each

of

the

two

conductors

should

be

locked

firmly

in

place

in

its

own

connector.

Take

the

other

end

of

this

wire

and

connect

the

bare

conductors

to

the

two

terminals

on

one

of

your

speakers,

Now

(this

is

important)

note

to

which

connector

(red

or

black)

on

the

A-401

,

and

to

which

speaker

terminal

,

the

coded

side

of

the

wire

is

connected.

Connect

the

other

speaker

to

the

other

two

connectors

under

SPEAKER

SYSTEM

1

,

being

sure

the

coded

side

of

this

wire

is

connected

to

both

the

A-401

and

the

speaker

in

the

same

way

as

the

first

wire.

The

left

channel

connection

should

be

made

to

the

speaker

placed

at

the

left

side

of

your

listening

area.

The

right

channel

connection

should

be

made

to

the

speaker

placed

at

the

right

side

of

your

l

istening

area.

Be

certain

(this

is

very

important)

all

these

connections

are

tight

and

that

all

the

strands

of

the

wires

are

firmly

seated

in

the

connectors

of

the

A-401

and

under

the

terminals

of

your

speaker

systems.

Any

loose

strands

of

wire

could

touch

other

terminals

and

cause

short

circuits,

which

might

cause

the

speaker

fuse

to

blow.

If

you

have

been

careful

to

follow

these

directions,

your

speakers

will

be

properly

"phased."

We

will

describe

how

to

chock

this

by

ear

when

the

other

connections

are

completed

and

your

system

is

operating.

If,

now

or

later,

you

wish

to

connect

a

second

pair

of

speakers,

you

can

use

the

SPEAKER

SYSTEM

2

connectors

of

the

A-401,

fol

lowing

the

procedure

outlined

previously.

The

speakers

in

your

system

should

ALL

have

a

rated

impedance

of

8

ohms

or

higher.*

Although

your

A-401

has

been

de-

signed

for

use

with

speakers

with

rated

impedances

of

8

or

16

ohms,

the

A-401

can

accommodate

ONE

pair

of

4

-ohm

speakers

adequately.

You

should

not,

however,

use

more

than

ONE

pair

of

4

-ohm

speakers.

Damage

to

the

A-401

could

result

from

such

use.

Turntables

or

AlltO111AC

Changers

All

record

playing

units

provide

two

or

three

cables

(aside

from

the

power

cord)

for

connection

to

the

A-401.

These

are

the

left

and

right

channel

signal

cables

and

the

ground

connection

(some

turntables

combine

the

ground

con-

nection

with

one

of

the

signal

cables).

The

two

signal

cables

are

usually

identified

as

"left

channel"

and

"right

channel"

by

the

use

of

a

color

code

or

tabs,

or

the

channel

identifications

are

molded

into

the

insulators

around

the

pin

-type

RCA

connectors.

Determine

which

of

the

cables

is

left

and

which

right

and

insert

them

into

the

two

corre-

sponding

receptacles

on

the

rear

panel

of

the

A-401

marked

PHONO.

Press

them

in

as

far

as

they

will

go

so

they

are

seated

snugly.

If

a

separate

ground

wire

is

provided,

connect

its

lug

or

stripped

end

under

the

knurled

nut

marked

GND

on

the

rear

panel

of

the

A-401.

The

phonograph

signal

connections

are

now

complete.

Insert

the

AC

power

cord

of

your

turntable

into

the

AC

receptacle

marked

UNSWITCHED

on

the

rear

of

the

A-401

.

This

receptacle

is

"live"

so

long

as

the

A-401

itself

is

connected

to

a

live

AC

outlet,

regardless

of

whether

the

A-401

is

itself

operating.

Your

turntable

or

automatic

changer

should

be

con-

nected

to

this

receptacle.

Note:

The

A-401

is

designed

to

operate

with

a

high

qual

ity

MAGNETIC

cartridge.

If

you

purchased

your

A-401

and

turntable

separately,

be

sure

the

turntable

is

equipped

with

a

cartridge

of

this

type.
