Before

beginning

to

make

connections,

make

certain

that

the

ignition

key

switch is

OFF.

Be

careful

to

install

the

amplifier

so

that

it

cannot

become

caught in

the

sliding

seat,

or

contact

the

car

chassis

with

its

terminals

or

wiring.

REMOTE

terminal

This

terminal

enables

the

power

switch

of

the

tuner/deck

to

also

turn

on

the

CA212.

Squeeze

the

neck

with

a

pair

of

pliers

to

clamp

the

wires,

and

then

connect

it

to

the

appropriate

wire

(power

amplifier

remote)

on

the

tuner/deck.

If

a

specific

wire

for

this

purpose

is

not

provided

on

the

tuner/

deck,

use

the

wire

for

controlling

the

power

antenna.

If

that

wire

is

already

connected

to

the

power

antenna,

the

CA212

can

be

connected

in

addition.

Should

no

power

antenna

wire

be

provided,

connect

the

wires

from

both

the

REMOTE

and

+B

terminals

to

the

ACC

circuit

of

the

car,

so

that

the

car

ignition

switch

will

turn

the

CA212

ON

and

OFF.

+B

terminal

The

+B

terminal

is

the

positive

power

input

terminal.

It

should

be

connected

to

a

circuit

which

is

turned

on

when

the

ignition

switch

is

in

the

ACC

position.

And

a

power

indicator

on

the

front

panel

lights.

GND

terminal

This

is

the

negative

power

input

terminal.

It

should

be

con-

nected

directly

to

the

car

chassis

using

the

accessory

black

wire.

It

is

not

necessary

to

connect

this

terminal

to

the

nega-

tive

battery

terminal.

Engine

noise

will

be

minimized

when

the

ground

wire

is

connected

to

the

same

point

at

which

the

in

-

dash

receiver

or

tuner/deck

is

grounded.

Speakers

wires

Connect

the

speaker

systems

to

these

wires.

Be

careful

to

connect

the

positive

speaker

terminals

to

the

positive

wires

(blue

and

red)

of

the

CA212.

Do

not

connect

the

negative

speaker

wires

(black)

to

the

car

chassis.

NOTE:

Some

cars

are

provided

with

speaker

wires

which

often

include

a

negative

wire

common

to

both

left

and

right

channels.

This

wire

should

not

be

used

with

the

CA212.

Be

sure

to

connect

the

negative

speaker

wires

from

left

and

right

channels

to

their

respective

wires

on

the

CA212.

INPUT

jacks

These

input

jacks

are

for

connection

to

the

line

(preamplifier)

output

jacks

on

the

tuner/deck.

It

is

recommended

that

high

quality

shielded

coaxial

cables

with

tight

-fitting

RCA

plugs

be

used

for

this

connection.

INPUT

SENSITIVITY

switch

This

switch

matches

the

input

sensitivity

of

the

CA212

to

the

output

level

of

the

tuner/deck.

If

the

rated

output

level

is

equal

to

or

more

than

0.5

volts

(500

millivolts),

set

this

switch

in

the

"LOW"

position.

Otherwise,

set

it

in

the

"HIGH"

position.

If

the

output

level

of

the

tuner/deck

is

not

known,

assume

that

it

is

more

than

0.5

volts.

When

operating

the

total

system,

if

it

is

necessary

to

turn

the

volume

control

of

the

tuner/deck

to

maximum

in

order

to

obtain

a

desired

listening

level,

then

the

output

level

is

likely

to

be

less

than

0.5

volts,

and

the

input

sensitivity

switch

should

be

put

in

the

"HIGH"

position.
