Denon DP-S1 Service Manual

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.

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
speed
synchronized
optical
link
(ST-GEN
LOCK)
1.
The
speed
at
which
data
transfer
is
a
very
rapid
50
Mbit/sec,
nearly
10
times
that
of
conventional
optical
links
(6
Mbit/sec}.
This
virtually
eliminates
transmission
distortion
due
to
signal
delay
(jitter).
2.
The
D/A
converter
master
clack
is
synchronized
with
the
CD
Transport
clock,
improving
clock
precision
and
suppressing
jitter.
3.
The
AT&T
ST-Link™
system
is
used
for
the
interface,
allowing
direct
one-way
connection
to
high
quatity
foreign-made
D/A
converters,
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.
300-ohm feeder cadis 7$-ahm coaxiat cedle
* 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

Only use discs which asxctusively contain audio signals
An electrical discharge due to static electricity may be
produced between the pin and your finger of any ather part of
your body it it 1s placed near the turntable pin whan the room
is dry and your body ts charged with static electricity
IHihts happens, the pickup may move slowly from the inside of
the disc towards the outside In this case. press the OPEN/
CLOSE button to close the door then open it back up The
pickup will ceturn to the inside of the disc and Ihe OP.S1 wilt
now operate normally
A metallic click may be heard when playback +s staried after
the stabilizer is placed on the disc
This ts the sound of the pin in the stabiliver which pravents the
stabilizer from slipning entering ihe guide pin groove, and 1s

A special shee! is attached 10 Ihe bottom of the stabitizer to
improve conlect between the stabilizer and the disc When the

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
