Introduction
Thank you for purchasing the Digital Link Sound System (XDP-PK1000).
This system allows you to digitally integrate an iPod/iPhone into your existing car audio unit.
You can enjoy exciting sound from your car audio unit and iPod/iPhone via this system, which
features sound settings optimized for your vehicle type by using Sony’s original digital sound
technology, and powerful bass delivered by the supplied subwoofer and amplifier.
The DSP master unit makes a natural “front sound field” possible, so that you can feel bass as
though it comes from directly in front of the driver’s seat even though the subwoofer is located
at the rear of your car, e.g., in a cargo area.
There is also a digital connection for an iPod/iPhone so that you can enjoy high quality sound
in your car without noise/distortion.
Enjoy the new sound experience with this Digital Link Sound System.
Getting Started
Resetting the unit
Before operating the system for the first time, or after replacing the car battery or changing
connections, you should reset the system (page 5).

Setting up the Cradle
Precautions
• Install the cradle on a dashboard properly so
that the unit will not interfere with normal
driving.
• Follow the instructions on this manual about
dealing with the suction cup to secure the
cradle on a dashboard. If you fail to do so,
the adhesive strength of the suction cup may
decrease, and the cradle may fall down.
• If the cradle becomes detached, a traffic
accident may result. To prevent this, use the
supplied strap.
• Keep the cradle out of the reach of children.
Should a small part of the cradle be
swallowed, immediately consult a doctor.
• Remove the cradle from the dashboard and
keep it out of direct sunlight after use.
Leaving it on a dashboard or in a car where it
will be exposed to high temperature may
cause malfunction, and it may also damage
the dashboard.
• An iPod/iPhone may not be charged if you
put it on the cradle when the temperature in
the car is extremely high/low.
• Be careful not to splash water on the cradle.
It may cause a malfunction.
• To disconnect the cradle cord, pull it out by
its connector, not the cord.
Parts List

Mounting sheet
Strap
Cord clamp
Cradle cable
Cleaning sponge for suction cup
Before Installation
• Mount the cradle on the dashboard where it
is smooth and horizontal.
• Make sure that the surface of the dashboard
where you intend to install the cradle is
clean. Dirty surfaces will make the adhesive
strength of the suction cup weak, and may
cause unstable installation of the cradle.
• The suction cup may leave a mark on the
dashboard, depending on the surface
material. Your consideration is requested.
To attach the mounting sheet
Attach the mounting sheet to the dashboard
before installing the cradle.

13
Notes
• Choose the mounting location carefully.
Practice installation before you actually mount
the sheet, if necessary.
• Removing the mounting sheet from the
dashboard decreases the adhesive strength of
the mounting sheet. It should not be reused
after removal.
1Peel the paper from the mounting sheet, and
then stick the mounting sheet to the
dashboard.
Allow 24 hours after sticking the mounting
sheet on the dashboard before installing the
cradle on it.
Installation
1Mount the clip of the strap on the
defroster of your car.
2Place the hoop of the strap over the
cradle and attach the strap as shown in
the illustrations below.
Notes
• After you attach the strap to the cradle, pull
the strap gently to make sure that the strap
is securely attached to the cradle.
• Do not forcefully pull the cradle after
attaching the strap. Doing so may damage
your car.
3Remove the cover from the suction cup
gently.
Note
• It may be difficult to remove the cover from
the suction cup as the adhesive strength of
the suction cup is strong.
4Press down the suction cup gradually,
expelling the air under the suction cup
(), and press the PUSH button to
attach the cradle on the dashboard
().
Notes
• If the suction cup contains air, the adhesive
strength of the suction cup will be
weakened.
• Make sure that the suction cup is dry before
mounting the cradle.
Peel off paper
Cover

14
Tip
• The suction cup may contain tiny holes.
This can occasionally occur in the
production process, and should not cause a
malfunction.
5Turn the LOCK/RELEASE lever
counterclockwise 90 degrees to secure
the cradle on the dashboard.
Note
• Before turning the LOCK/RELEASE lever,
make sure that you have pressed the PUSH
button hard and expelled the air from under
the suction cup.
6Connect the cradle cable.
Rotate the arm of the cradle to the
horizontal position, and connect the
cradle cable.
Notes
• Make sure that the  marks on the
connector are visible, as shown in the
illustration, when connecting the cradle
cable.
• Do not use any cable other than the supplied
cradle cable.
7Adjust the strap.
Adjust the strap by using the adjuster.
To remove the cradle
1Press the ridges to remove the cradle cable
from the cradle.
2Loosen the strap from the adjuster.
3Take the hoop of the strap off from the
cradle.
4Turn the LOCK/RELEASE lever clockwise
by 90 degrees.

5Pull the tab of the cradle for a few seconds in
the direction of the arrow marked in the
illustration below (), and then slowly
(over 3 to 5 seconds) remove the suction cup
().
Notes
• Pull the cradle by its tab when you remove
the suction cup from the dashboard.
• Doing any of the following may damage the
suction cup.
– press/pull the cradle by its tab in a
horizontal direction.
– insert a hard object (key, blade, finger,
etc.) between the suction cup and the
dashboard to remove the suction cup
from the dashboard.
• The suction cup may be damaged if it is
forcefully removed, or the cradle is forced in
a horizontal direction while still attached to
the dashboard, or put the pressure on the
cradle in the horizontal direction before
completely taking off the suction cup from
the dashboard.
• If the temperature of the surface of the
dashboard is low, for example, in winter or
when used in a cold region, removal of the
suction cup may be difficult.
6Replace the cover on the suction cup.
Note
• Put the cover on the suction cup when you
take the cradle off the dashboard. If the
suction cup becomes dirty or scratched, its
adhesive strength will be reduced.
Arranging the cradle
cable
Use the cord clamp to secure the cradle
cable.
Note
• Clean the surface where you intend to install
the cord clamp.

Playback
Precautions
• For safety reasons, keep your car audio unit
and iPod/iPhone volume moderate so that
you can still hear sounds outside your car.
• Do not watch an iPod/iPhone while driving.
It is dangerous and may cause a traffic
accident. If you need to operate the iPod/
iPhone or the cradle, or take a phone call, be
sure to stop your car in a safe place before
operating the iPod/iPhone or the cradle or
taking a phone call.
• An iPod/iPhone’s Screen Rotation function

and iPod/iPhone volume moderate so that
you can still hear sounds outside your car.
• If you have any questions or problems
concerning the system that are not covered
in this manual, please consult your nearest
Sony dealer.
Fuse replacement for the amplifier and
the DSP master unit
If a fuse blows, check the power connection
