FEATURES
The
DP-S?
is
a
top
quality
CD
transport
developed
based:on
a
policy
of
fully
eliminating
vibration
and
resonance
within
an
innovative
design.
Vibration
and
resonance
are
eliminated
through
a
newly
developed
pickup
mechanism,
a
large
stabilizer,
triple-Jayer
flotation,
and
a
frame
design
which
keeps
the
influence
of
external acoustic
pressure
to
the
absolute
minimum,
The
OP-S1
provides
five
types
of
digital
outputs
and
an
ultra
high-speed
synchronous
optical
tink
(ST-GEN
LOCK)
for
ultimate
synchronized
driving.
(1)
(2)
(3)
(4)
Newly developed pickup mechanism unit
1.
A
strong
cast
aluminum
pickup
base
thoroughly
eliminates
extraneous
vibration.
2.
A
high
torque
motor
provides
accurate,
extremely
smooth
rotation,
minimizing
jitter.
In
addition,
the
self-centering
stainless
stee!
turntable
is
driven
with
an
ultra-thick
spindle
shaft
(6mm
in
diameter),
and
a
very
hard,
low
friction
ruby
(5mm
in
diameter)
is
used
for
the
bearing,
providing
outstandingly
high
endurance.
3.
The
opening
of
the
disc
loading
section
is
air-shielded
with
a
special
rubber
material
to
suppress
the
effect
of
air
vibration
entering
through
gaps,
greatly
improving
the
airtightness
of
the
pickup
mechanism.
Extremely
stable
disc
playback
thanks
to
a
large
stabilizer
(included)
1.
The
stabilizer
holds
the
disc
down
to
correct
any
warping
in
the
disc
and
prevent
jitter
during
signal
readout.
2.
The
stabilizer
also
thoroughly
suppresses
any
resonance
in
the
disc
itself.
3.
The
moment
of
inertia
generated
by
the
stabilizer,
which
is
heavier
than
the
disc,
creates
extremely
stable
rotation
and
improves
the
readout
jitter
margin.
Thorough anti-resonant construction
1.
The
large
insulator
absorbs
vibrations
from
the
Noor
through.a
combination
of
aluminum
and
sintered
alloy.
2,
The
mechanism
base
which
supports
the
pickup
mechanism
is
floated
from
the
frame
with
elastic
tubber.
3.
The
pickup
mechanism
is
itself
floated
with
an
oil
damper
and
spring.
This
Triple
Floating
Mechanism
structure
shuts
out
external
vibration
to
provide
playback
with
excellent
vibration
resistance.
4.
The
highly
rigid
pickup
mechanism
is
placed
at
the
center
where
it
is
least
likely
to
be
affected
by
external
vibration.
This
also
makes
for
excellent
weight
distribution.
5.
The
heavyweight
chassis
and
low
center
of
gravity
create
an
ideal
non-resonant
design.
6.
The
design
makes
use
of
spherical
surfaces
and
radial
forms
to
keep
the
influence
of
external
acoustic
pressure
to
a
minimum.
Synchronized
driving
with
an
ultra
high

is
a
very
rapid
50
Mbit/sec,
nearly
10
times
that
of

This
virtually
eliminates

due
to
signal
delay
(jitter).
2.
The
D/A
converter
master
clack
is
synchronized
with
the
CD

clock,
improving
clock

and
suppressing
jitter.

INSTALLATION PRECAUTIONS
Ifthe DP-S# or other electrome equipment using microprocessors
is used at the same time as a tuner of TV, norse or disturbance
may de produced in the sound or picture on the tuner or TV. If this
should happen, piease take the following measures
* Keep the DP-S1 as far away from the tuner or TV set as
possible.
© Keep the power cable and connecting cables of the OP-S1
separate trom the antenna wires of the tuner and TV.
© Interference is particutarty likely to occur when an indoor
antenna or 8 300-ohm feeder cable is used ~ us. use of an
outdoor antenna and 75-ohm coaxial cable is strongly recom
mended.

* Norse may be heard in AM or FM broadcasts if the DP.S1 is
turned on while listening to AM or FM broadcasts. if this
happens, turn the OP-S1's power off
* Humming may occur if the DPS) is installed near a TV or
other audio component or if ther connection cords are nearby
if this happens, try setting the components or ther connection
cords 1A a different position
* Always remove discs whan moving the OPS) Discs may be
damaged if teft in the OP St}
* Do not insert any objects other than discs in the disc insertion
stot, as this may damage the OPS!
* Do not move the OP-S1 suddenly from a cold place lo a warm
one I this ts done, water droplets (condensation) may form on
the lens, in which case the OP-S1 will not operate properly. If
this happens, wart 30 minutes before using the DP-S1

Precautions on storage
e After playing a disc, always return it to its case
¢ Keep discs in the cases when they are ndt to be played. This
‘will protect them from dust and dirt and prolong their
service life

Caution for Handling the Laser Pick-up
The laser pick-up KSS-151A is assembied and precisely ad-
justed using a sophisticated manufacturing process in our plant.
Do not disassembie or attempt to readjust it. Please keep the
following instructions carefully in handling pick-up.
1. General Care
(1) Storage
Do not store the pick-up in dusty, high-temperatured or
high-humidity environments.
(2) Please take care for preventing from shock by falling down
or careless handling.
2. Laser Diode (LD)
(1) Protect your eyes
The laser beam may damage the human eye, since the
intensity of the focused spot may reach 1.3 x 10*W/cm? even
it the intensity at the objective lens is 400 u.W maximum. As
the light beam spreads ~‘ter focused through the objective
lens, it does not effect you in the place as far as more than
30 cms. However, do not look at the laser light beam either
through the objective lens directly nor another lens or a
mirror.
(2) Poison of As
Since the LD chip contains As (Arsenic), as GaAs + GaAlAs,
as known as the poison, although the poison is relatively
weak, in comparing with others, e.g.As2O3, AsCis etc., and
the amount is small, avoid putting the chip in acid or an alkali
solution, heating it over 200°C or putting it into your mouth.
(3) Avoid surge current or electrostatic discharge
The LD may be damaged or deteriorated by its own strong
light if a large current is supplied to it, even if only a short
pulse.
Make sure that there is no surge current in the LD driving
circuit by switches or else. Be careful to handle pick-up as it
may be damaged in a moment by human electrostatic dis-
charge. The pins of the LD are short-circuited by solder for
protection during shipment [Solderded short circuit portion
(A)].
For safety handling of an LD, grounding the human body,
measuring equipments and jig is strongly recommended.
And still it is further desirable to make use of mat on the
platform and floor for handling the LD.
To open the short-circuit, remove the soldering quickly with
a soldering iron whose metal part is grounded.
The temperature of the soldering iron should be less than
320°C (30W).
3. X-axis Actuator
(1) The performance of the actuator may be effected if magnetic
material is located nearby, since the actuator has a strong
magnetic circuit. Do not permit dust to enter through the
clearance of the cover.
(2) Cleaning the iens
It may change the specifications when dust or dirt is stuck
on the object lens. For cleaning, use a dry lens cleaning
paper applying no excessive pressure to the lens. If it is
difficult to remove it, moisten the paper with a little amount
of water. At this time never drip water other than the lens
portion.
4. Metal Bearing
The metal bearing of Cu-compound sintered. alloy is impreg-
nated with oil. However, supply oil with the specified oi] FROIL
947P(529 0054 007), at the pick-up replacing time. You do not
normally need jublicate the bushing in initializing time nor sup-
plying oil inrunning time.
5. Handling
Please handle the laser pick-up with holding by opticai base.
When either a part of human body or some other things may
happen to touch directly with the circuit part of either the LD or
PD PCB, it may cause deterioration, take careful attention in
handling this base.
6. Deterioration of Laser Pick-up
When difficulty occurs either in focus or tracking adjustment nor
abie to adjust the focus or tracking, it seems that the laser
pick-up is deteriorated. In these cases, check a value of laser
diode current and give a decision for deterioration.
7. Fundamental! Deterioration Decision of Laser Pick-up
(1) It a voltage value in across Pin © of TP102 (+5V) and pin
@ (iop) of Unit (3U-2415) is V1, the value of laser diode
current “iop 1” can be found a formula
. v1
“iop 1° = ——
1op 2 -
(2) If a “iop" exceeds + 10% compared with the IOP indication
on the laser pick-up nameplate, there is a fair chance i.
deterioration when it is checked under a circumambient
temperature 23°C.
(3) When the circumambient temperature changes + 10°C, "iop
1" will change + 5%. The “iop 1° will also be changed by the
passage of time.
(4) in case of the above conditions taking into consideration and
performed the adjustment in proper way, if the HF level
across pin @ (HF) of TP102 and across GND of TP101 in
3U-2415 becomes 0.6V or jess values; or a jitter occurs
great, the laser pick-up may be detenorated.
