height

(distance

between

the

stylus

surface

when

the

cueing

lever

is

raised)

has

been

adjusted

at

the

factory

before

shipping

to

approximately

8~13

mm.

{f

the

clearance

becomes

too

narrow

or

too

wide,

turn

the

adjustment

screw

clockwise

or

counterclockwise

while

pushing

the

arm

down.

Clockwise

—distance

between

the

record

and

stylus

tip

is

decreased.

Counterclockwise

rotation

—distance

between

the

record

and

is

increased.

Note:

As

the

adjusting

screw

has

a

hexagonal

head,

be

sure

to

make

the

adjustment

while

depressing

the

arm

lift,

or

the

screw

will

not

move

freely.

Also

be

sure

that

the

hexagonal

head

retracts

correctly

into

the

when

the

latter

is

released.

Use

utmost

care

when

the

arm

ciamp.

After

play

is

finished,

if

the

is

not

to

be

used

for

some

time,

care

should

be

taken

to

secure

to

protect

the

reason,

the

should

also

be

attached.

@

Dust

and

should

be

carefully

removed

from

Dust

and

dirt

on

the

stylus

not

only

result

in

Aluminum

base

material

provide

acoustic

isolation

The

effects

of

external

vibrations

are

dramatically

reduced

in

the

turntable

by

this

new

turntable

construction.

The

turntable

base

is

precision-made

aluminum

diecast.

And

the

underside

of

the

main

base

is

made

of

a

heavy

rubber

material

which

has

excelient

vibration

resistance

and

absorbing

characteristics.

The

turntable

platter

is

also

vibra-

tion-damped

with

specially

fabricated

rubber

matting

in

the

underside

along

with

the

thick

turntable

sheet

(rubber

mat).

Four

large-size

insulating

feet

also

help

to

absorb

unwanted

vibrations.

These

features

make

the

SL-1200MK2

ideal

for

use

@

High

torque

for

fast

starts

The

integral

rotor/platter

motor

delivers

1.5kg-cm

(1.3

starting

torque.

This

high

torque

gives

very

quick

starts

enabling

the

platter

to

reach

33-1/3

rpm

within

0.7

s.

(a

quarter

of

a

turn).

This

is

a

big

advantage

in

many

professional

applications

where

fast

cueing

is

a

necessity.

of

which

is

precisely

defined

at

Bearings

are

finished

to

a

tolerance

of

+0.5

This,

and

the

extra-closeness

of

result

in

the

minimal

friction

of

7

(0.007

for

Add

to

this

the

(including
