ADJUSTMENT

PROCEDURES

Adjustments

and

Checking

the

Protection

Circultry

1.

Preparations

1)

Place

the

unit

on

the

workbench.

(There

should

be

about

15

mm

of

space

between

the

base

plate

of

the

unit

and

the

work

surface.)

2)

Set

up

the

unit

as

follows.

(1)

No

load

(2)

No

signal

(3)

Volume

turned

all

the

way

down

(4)

Speaker

switch

OFF

(5)

Power

switch

OFF

Note)

Check

the

following

points

before

making

adjustments

(1)

The

power

switch

should

be

OFF.

(2)

The

interior

of

the

unit

should

not

be

warm.

2.

Idling

current

adjustment

1)

Turn

the

power

switch

ON

and

allow

the

unit

to

warm

up

for

about

10

minutes.

(1)

Adjust

R535

(R536)

so

that

the

voltage

at

test

point

VCT-ITD

on

the

NAAF-4209

circuit

board

is

1SmV+t5mV.

Note)

Semi-fixed

resistors

enclosed

in

parentheses

(_

)

are

for

the

right

channel.

3.

Check

of

operation

of

protection

circuitry

1)

Check

of

operation

of

protection

relay

(1)

Confirm

that

the

relay

turns

ON

approximately

5

seconds

after

the

power

switch

is

turned

ON.

(2)

The

SERVO

indicator

LED

should

light

at

the

same

time.

(3)

The

relay

should

turn

OFF

approximately

0.5

seconds

after

the

power

switch

is

turned

OFF.

2)

Check

of

DC

detection

and

servo

circuitry

operation

(1)

Turn

the

power

on

with

no

load.

(2)

After

the

speaker

relay

turns

ON,

apply

DC+200mV

to

the

CD

input

terminals.

Confirm

that

the

relay

turns

OFF.

(3)

Confirm

that

operation

is

the

same

as

(2)

above

when

an

input

of

DC—200mV

is

applied.

Note)

Under

no

circumstances

connect

a

load

or

short

the

speaker

terminals

when

performing

the

above

test.

3)

Signal

input

from

the

circuit

illustrated

below

with

no

load.

(1)

Confirm

that

the

speaker

relay

does

not

turn

OFF

even

when

a

2

ohm

load

is

connected

when

a

peak

value

of

30Vp

is

output.

(2)

Next,

confirm

that

when

a

1

ohm

load

is

connected

the

speaker

relay

switchse

OFF

and

ON

a

couple

of

times

and

then

stays

OFF.

Note)

The

period

before

that

relay

stays

OFF

should

not

last

for

more

than

1

minute,

Relay

OFF

status

can

be

canceled

by

switching

the

power

OFF.
