This

turntable

is

available

in

two

models:

one

with

a

Pioneer

phono

cartridge,

and

the

other

without

a

phono

cartridge.

The

perform-

ance

and

functions

are

the

same.

These

OPERATING

INSTRUC-

TIONS

are

based

on

the

former

PL-520.

PL-520

FEATURES

Brushless

DC

Servomotor

with

Hall

Elements

The

PL-520

incorporates

a

high-precision

phonomotor

combin-

ing

control

circuitry

composed

of

semiconductors

with

Hall

elements

in

the

brushless

DC

motor.

The

speed

of

the

platter

is

smooth

since

the

Hall

elements

guarantee

accurate

position

detection

and

the

motor's

winding

current

is

controlled

by

transis-

tors.

Another

feature

is

the

high

inertia

platter.

Altogether,

these

attractive

features

make

for

a

signal-to-noise

ratio

of

more

than

73dB

(DIN-B)

and

a

wow

and

flutter

of

less

than

0.03%

(WRMS).

Two-motor,

Full-automatic

Turntable

with

Precision

Geared

Motor

Mechanisms

The

lead-in

and

return

of

the

tonearm

are

performed

by

a

special

precision

geared

motor

mechanism

which

does

not

affect

the

speed

of

the

platter

at

all.

Furthermore,

a

speed

detection-type

auto-return

mechanism

controls

the

tonearm

for

accurate

and

stable

operation

every

time

it

is

returned

to

the

arm

rest.

Switches

and

Controls

are

Located

at

the

Front

for

Easy

Operation

The

two-speed

fine-adjustment

knobs

for

adjusting

the

speed

of

the

platter,

the

push-button

speed

selector

switch,

the

size

selector

for

selecting

the

size

of

the

records,

the

stop

button,

repeat

button

and

start

button

are

all

located

on

the

front

panel.

This

means

that

you

don’t

have

to

lift

the

dust

cover

every

time

you

want

to

make

an

adjustment.

[t

also

means

that

it

is

much

easier

to

use

this

turntable

on

a

shelf

or

audio

rack,

High-sensitivity

Tonearm

with

Excellent

Trackability

The

newly

developed,

high-sensitivity

S-shaped

tonearm

comes

with

built-in

lateral

balance

and

anti-skating

mechanisms

and

it

displays

excellent

tracking

performance

with

a

light

tracking

force

cartridge.

There

is

a

separate

tracking

force

weight

in

front

so

that

you

can

easily

change

the

tracking

force

even

if

you

have

mounted

your

turntable

in

an

audio

rack.

INTERRUPTING

RECORD

PLAY

Set

the

arm

elevation

lever

to

the

UP

position.

The

arm

elevation

mechanism

is

independent

of

the

auto

mechanism

and

so

the

tonearm

will

ascend

and

descend

irrespective

of

whether

the

turntable

is

set

to

auto

play

or

to

manual

play.

This

is

a

convenient

function

since

it

allows

you

to

choose

just

the

tracks

you

want

to

hear

from

an

LP.

RELEASING

REPEAT-PLAY

MECHANISM

The

repeat

mechanism

only

is

released

when

you

push

the

REPEAT

button

during

repeat

play

and

then

take

your

finger

off

the

button.

The

turntable

is

then

set

to

the

normal

auto

play

mode.

OPERATION

PRECAUTIONS

Always

set

the

record

size

selector

before

you

push

the

START

and

REPEAT

buttons

when

you

want

to

set

the

turntable

to

the

auto

play

or

repeat

play

modes.

This

is

because

the

stylus

will

not

descend

where

you

want

it

to

descend

if

you

change

the

setting

of

the

record

size

selector

while

the

tonearm

is

moving.

You

may

also

damage

the

stylus

and

the

record.

Always

clean

the

stylus

both

before

and

after

playing

a

record

with

a

soft

brush

and

try

to

make

it

a

rule

to

clean

the

records

with

a

good

quality

cleaner.

When

changing

over

the

headshell,

clamp

the

tonearm

to

the

arm

rest

so

that

the

tonearm

shaft

is

not

strained

in

any

way.

Be

careful

not

to

make

the

turntable

vibrate

while

a

record

is

playing

since

this

can

result

in

damage

to

the

stylus

and

record.

Do

not

force

the

tonearm

closer

than

40mm

to

the

center

shaft

or

away

from

the

arm

rest.

If

this

distance

is

exceeded,

you

may

damage

the

internal

mechanisms

and

render

automatic

ope-

ration

ineffective.

Place

only

one

record

at

a

time

on

the

platter.

If

two

or

more

records

are

stacked

on

the

platter,

the

stylus

will

not

make

proper

contact

with

the

grooves,

and

this

will

impair

the

quality

of

reproduction.

Do

not

disconnect

the

power

cord

while

the

stylus

is

still

in

a

record

groove

as

this

may

result

in

damage

to

the

stylus

and

record.

GENERAL

PRECAUTIONS

CABINET

When

the

dust

cover

or

the

cabinet

is

dirty

or

dusty,

wipe

them

clean

with

a

polishing

cloth

or

soft

cloth.

Do

not

use

furniture

wax

or

bring

the

turntable

into

contact

with

benzine,

insecticides

or

any

other

inflammable

material

since

they

will

corrode

the

outside

of

the

turntable.

MOTOR

WORKS

PROPERLY

AFTER

PLATTER

IS

MOUNTED

If

the

motor

is

run

with

the

platter

removed,

the

motor

will

not

operate

normally

and

may

seem

to

have

broken

down.

If,

however,

the

platter

is

mounted,

the

motor

will

rotate

properly.

LUBRICATION

There

is

no

need

to

lubricate

the

PL-520

since

it

employs

oil-less

bearings

in

the

rotating

parts.

If

the

turntable

is

brought

into

the

warm

from

previously

cold

surroundings,

or

if

the

room

temperature

rises

suddenly,

moisture

will

form

on

the

operating

sections

and

the

turn-

table

will

not

be

able

to

display

its

perform-

ance

to

the

full.

If

confronted

with

a

situation

like

this,

leave

the

turntable

in

its

new

environment

for

about

an

hour

or

try

and

increase

the

room

temperature

gradually

before

operation.
