We want to thank you for selecting the SL-1 015.
For optimum performance, we recommend that you
read these instructions carefully.
The SL-1015 is a high performance turntable
system which consists of a tonearm (EPA-500)
designed with compatibility of the cartridge and
tonearm

in

mind a high performance turntable base
(SH-15B 1) designed with emphasis on its damping
characteristics produced by one-piece molding of
special viscoelastic material and a quartz
synthesized system direct drive turntable (SP-15)
capable for the first time in the world of digital pitch
control at

±9.9%

through 0.1 % steps.

If

you purchase the optional tonearm unit according

to the characteristics

of

the cartridge you use, you
can upgrade your system as easily as replacing the
headshell.

Before use

Caution:

Never

connect

the

AC

power

plug

before

asse

has

been

completed

.

.)
Note:
To

prevent

damage

to

the

assembly

. it is

recommended

that

it be

removed

from

the

cartridge

during

installation

.

If the

cartridge

being used

has

a ligh

ter

side

value

within

the

appropriate

cartridge

weight

range

and

is to

be

used

under a heavy side

stylus

pressure

within

the

specified

stylus

pressure

range

. attach the

headshell

weight

between

the

headshell

and

cartridge

main

body

.

• Concerning the arm clamp

(See

Fig.

4.)

An

arm

clamp

is

employed

to

lock

the

rotating

section

of the

gimbal

suspension

in

place. When

instatling

the arm unit

or

when

nol

using

the

turntable, lock

the

tonearm

suspension

with

the

clamp

.

I! the

arm

clamp

is

not

locked, the

pivots will

move

and

if

the

arm

unit

has

been

installed, this

might

result

in

damage

to

the stylus

.

• Installation of the arm unit (See

Figs. 5 and

6.)

Align

the

mounting

section

of

the arm unit

with

that of the

arm base,

and

while

sliding

it in the

direction

of the

arrow,

insert

it

until

it

arrives

at

the

fixed

position

and

stops. Then

secure

it

with

the

arm-unit

lock

screw

.

Note:

eWhen

installing

or

removing

the

arm

unit,

be

sure

to

turn

the

amplifier's

volume

control

to "

0"

or

turn

off

the

amplifier's

power

before

loosening

the

Adjustment

of

stylus

pressure

gauge

In

order

to obtain

precise

measurement

. ea ch time you use

the

gauge

make

adjustments following the

procedure

shown

below

:

1. Turn the

power

switch to

[on]

. The LED lamp will light up

2.

Turn the zero adjustment knob towards

[+

I or [ - ] until

the

needle

indicates

[0].

(See

Fig.

12.)

3.

Place

the

recessed

part

of

the

provided

gain adjustment

weight

on the

protruding

part

of the

stylus

set

plate

and

turn the

gain

adjustment

knob

towards

[+]

or [- I

until

the

needle

indicates

[.)

. (See

Fig. 13.)

Note

:

Should

the needte not

indicate

[01

even when the zero

adjustment

knob

is rotated,

adjust

by rotating the zero

adjustment

knob

and the

gain

adjustment

knob

fully

towards

the

[+)

side

, and turn

the

votume controt (Fig.

15)

at

the

bottom

portion

of the

stylus

pressure

gauge

either

clockwise

or

counterclockwise

by a

screwdriver

to

bring the

needle

between

[2.5)

and

[3].

(See

Fig. 12.)

Subsequently,

make

zero

adjustment

according to the

procedure

in

item

2.
Note:
eThe

~tylus

pressure

gauge

should

never

be

placed

on

the

surface

of a

record.

eWhen

making

adjustments

using

the

gauge

, wait about

10

seconds

after

switching the

unit

on. Also, several

seconds

are

required

for the

needle

to return to the [D)

position, but

this

is

caused

by a temperature

com-

pensation

mechanism

and

is

not

due to

any

fault in the

performance

.

eDo

not

move

the gain

control

until

the zero adjustment

has

been

completed,

and

do

not

perform

the

operations

in

reverse

.

eAfter

use, be

sure

to switch

off

the

power

to prevent

unnecessary

battery

consumption.

Forgetting

to

switch

off

the

power

will wear out the

batteries

in

about

10 hours, thus making it

impossible

to

use the gauge.

•

Selling

the

stylus

pressure

The stylUS

pressure

gauge

is

grooved

on its

side

in

order

to

be

used

in a

stable

position

on the platter.

Secure

it by

placing

it on the

center

spindle. (See

Fig.

14.)

Note

center

spindle

of the

turntable

in

use

is long , or if

any

other

part

except

the

stylus

comes

into

contact with

the

stylus

pressure

gauge,

move

it slightly away from the

spindle

. Also,

smoother

adjustment

can be

performed

if

the turntabte

platter

is

prevented

from rotating.

1.

Loosen

the weight

lock

screw

by turning it in a counter-

clockwise

direction

.
