WARNING
To prevent fire or shock
hazard, do not expose the
unit to rain or moisture.
Precautions
On safety
Should any solid object or liquid fall into
the cabinet, unplug the processing
amplifier and have it checked by qualified
personnel before operating it any further.
On power sources
• Before operating the processing
amplifier, check that the operating
voltage is identical with your local
power supply. The operating voltage is
indicated on the nameplate at the rear of
the processing amplifier.
• The unit is not disconnected from the AC
power source (mains) as long as it is
connected to the wall outlet, even if the
unit itself has been turned off.
• If you are not going to use the processing
amplifier for a long time, be sure to
disconnect the processing amplifier from
the wall outlet. To disconnect the AC
power cord, grasp the plug itself; never
pull the cord.
• AC power cord must be changed only at
the qualified service shop.
• The voltage selector is located at the
bottom of the apparatus.
On placement
• Do not install the appliance in a confined
space, such as a bookcase or built-in
cabinet.
• Place the processing amplifier in a
location with adequate ventilation to
prevent heat buildup and prolong the
life of the processing amplifier.
• Do not place the processing amplifier
near heat sources, or in a place subject to
direct sunlight, excessive dust or
mechanical shock.
• Do not place anything on top of the
cabinet that might block the ventilation
holes and cause malfunctions.
On operation
Before connecting other components, be
sure to turn off and unplug the processing
amplifier.
On cleaning
Clean the cabinet, panel and controls with
a soft cloth slightly moistened with a mild
detergent solution. Do not use any type of
abrasive pad, scouring powder or solvent
such as alcohol or benzine.
If you have any question or problem
concerning your processing amplifier,
please consult your nearest Sony
dealer.

zWhen to replace the batteries
Under normal use, the batteries should last for about 6 months.
When the remote no longer operates the processing amplifier,
replace both batteries with new ones.
Notes
• Do not leave the remote in an extremely hot or humid place.
• Do not use a new battery with an old one.
• Do not expose the remote sensor to direct sunlight or lighting
apparatuses. Doing so may cause a malfunction.
• If you don’t use the remote for an extended period of time,
remove the batteries to avoid possible damage from battery
leakage and corrosion.

Getting Started
Checking the Necessary Components
This digital processing amplifier lets you enjoy sound
recorded on a DVD with surround effects.
Sound signals recorded on a DVD are decoded and then
sent to the connected speakers.
You can enjoy 5.1ch surround sound by using the
processing amplifier together with an existing stereo
system or stereo amplifier, or 3ch surround sound when
using the processing amplifier alone.
z5.1ch and 3ch
Surround sound is basically 5.1ch. The “5” in 5.1ch indicates five
speakers (two front speakers (L/R), one center speaker, and two
rear speakers (L/R)), and the “1” indicates one sub woofer.
Dividing the sound between these five speakers and one sub
woofer reproduces realistic sound with a sense of space. When
the shape of the room or other conditions prevent you from
connecting five speakers, you can still enjoy surround effects
using only the three front and center speakers (3ch).
zSub woofer
The sub woofer reinforces the bass sound. You can enjoy
satisfactory surround effects even without a sub woofer, but
using a sub woofer lets you obtain heavier bass sounds for more
realistic surround effects.
To enjoy 5.1ch surround sound
You can enjoy 5.1ch surround sound by using the
processing amplifier together with any of the following
stereo systems or stereo amplifiers. See “Connections and
Setup for 5.1ch Surround” on page 6 for a description of
the necessary connections and setup.
πRecommended Sony stereo system model:
DHC-MD717 (This model may not be sold in certain
countries)
πStereo systems or stereo amplifiers with audio input
jacks for external components.
To enjoy 3ch surround sound
You can enjoy 3ch surround sound by using only the
processing amplifier and a DVD player. See “Connections
and Setup for 3ch Surround” on page 16 for a description
of the necessary connections and setup.

Connections
and Setup for
5.1ch Surround
This section describes the connections
and setup necessary to enjoy 5.1ch
(SYSTEM UP MODE) surround sound
together with your existing
components.
Hooking Up the System
Checking the connection type
The connections differ according to the components used
together with the processing amplifier. Be sure to check
your existing components and the connection type
beforehand.
Differences in functions for each
connection type
For connection type A, the volume adjustment is
controlled and the speaker volume balance set by the
TEST TONE function is constantly maintained by the
audio bus cord connection, so these items do not need to
be reset.
For connection type B, the volume control of the
connected stereo system or stereo amplifier changes only
the front speaker volume, disrupting the volume balance
set by the TEST TONE function.
To return each speaker to the original volume balance,
adjust the volume control of the connected component so
that the front volume matches that of the other speakers,
or do the TEST TONE adjustment again.

Connections and Setup for 5.1ch Surround
What cords will I need?
πOptical cable (supplied, 1)
This is used to connect a DVD player.
This cable is not necessary when connecting the DVD
player with the coaxial digital connecting cable.
πCoaxial digital connecting cable (1)
This is used to connect a DVD player.
This cable provides better sound quality than
connection with the optical cable.
z
When you connect both the optical cable and the coaxial
digital connecting cable, press OPTICAL (optical digital) or
COAXIAL (coaxial digital) on the processing amplifier to
select the sound you want to listen to during playback.
πAudio cord (supplied, 1)
This sends the front speaker sound from the FRONT
OUT jacks of the processing amplifier to the front
speakers through the stereo system or stereo amplifier.

Connections and Setup for 5.1ch Surround
Connecting a DVD player and other components to the processing amplifier
Connect the cords and cables according to the procedure 1to 4shown in the illustration below depending on the
connected component type Aor B.
Be sure to turn off each component before connecting the cords and cables. Also, do not connect the power cord of the
processing amplifier to an AC outlet before completing all speaker and sub woofer connections (see page 10).
Type AType B
1Set the voltage selector.
Check that the voltage selector on the bottom of the
processing amplifier is set to the local power line
voltage. If not, set the voltage selector to the correct
position using a screwdriver before connecting.
2Connect the DVD player.
Connect the DVD player with the optical cable or the
coaxial digital connecting cable. For better sound
quality, we recommend using the coaxial digital
connecting cable.
Notes
• Do not stack the DVD player on top of the processing amplifier,
as the heat emitted from the processing amplifier may cause
the DVD player to malfunction.
• This processing amplifier does not support 96 kHz or 24-bit
discs.
Connecting the optical cable
Connect the cable plugs to the DIGITAL OUT
OPTICAL jack on the DVD player and the DIGITAL
OPTICAL IN jack on the processing amplifier.
Remove the cap from each jack (1and 3) and insert
the plugs parallelly until they click into place (2and
4).
