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 receiver
and have it checked by qualified
personnel before operating it any
further.
On power sources
To avoid electrical shock, do not open
the cabinet. Refer servicing to qualified
personnel only.
Do not install the appliance in a
confined space, such as a bookcase or
built-in cabinet.
• Before operating the receiver, 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 receiver.
• The receiver is not disconnected from
the AC power source (MAINS) as
long as it is connected to the wall
outlet, even if the receiver itself has
been turned off.
• If you are not going to use the
receiver for a long time, be sure to
disconnect the receiver from the wall
outlet. To disconnect the AC power
cord, grasp the plug itself; never pull
the cord.
• Should the AC power cord need to be
changed, have it done at a qualified
service shop only.
On placement
• Place the receiver in a location with
adequate ventilation to prevent heat
build-up and prolong the life of the
receiver.
• Do not place the receiver 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
receiver.
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 receiver, please
consult your nearest Sony dealer.

Presetting Radio Stations
You’ll most likely want to preset the receiver with the
radio stations you listen to often so that you don’t have
to tune in the station every time. The receiver can store
a total of 30 FM or AM stations. You can store the
stations on preset numbers combining 3 characters (A,

Using Surround Sound
Enjoying Surround Sound
You can take advantage of surround sound simply by
selecting one of the pre-programmed “sound fields”
that your receiver provides. You can enjoy the sound of
a movie theater or concert hall in your own home. You
can even customize a sound field by adjusting its
parameters.
Sound field are classified into three types.
One type is “CINEMA”. The CINEMA type sound
fields are designed for enjoying movies recorded on
videos or laser discs. Four sound fields are included in
the CINEMA type and they are grouped into two
types. PRO LOGIC sound field can be used to
reproduce plain surround sound. When you select the
PRO LOGIC sound field, the receiver obtains full
surround sound by using Dolby Pro Logic to decode
Dolby Surround encoded software. The surround
sound is reproduced in the exact way that the sound
engineer of the software intended. Other sound fields
in the CINEMA type are designed to add more
reverberation effects by incorporating Digital Cinema
Sound technology. When you select these sound fields,
the receiver adds the reflection and reverberation
effects that are typical in movie theaters to the decoded
Dolby Pro Logic Surround sound. You can enjoy the
sound that you would experience in the movie theater.
Using Surround Sound
The third type is “MUSIC”. When a sound field in this
type is selected, the receiver adds the reverberation to
the normal 2-channel stereo sound. You can apply
these sound fields when playing a CD or watching TV
programmes to obtain the surround effects of concert
hall or a jazz club.
To enjoy Dolby Pro Logic Surround sound fully, do the
procedure on “Dolby Surround Setup” starting from
page 10 to select the centre mode and adjust the
speaker volume.

sound field.
The receiver memorizes the last sound field selected
for each programme source (Sound Field Link)
Whenever you select a programme source, the sound
field that was last applied is automatically applied
again. For example, if you listen to CD with HALL as
the sound field, change to different programme source,
then return to CD, HALL will be applied again. In the
case of the tuner, the sound fields for AM or FM band
and for all the preset stations are memorized separately.

Customizing Sound Fields
By adjusting some of the sound parameters, you can
customize sound fields to suit your particular listening
situation.
Once you customize a sound field, the changes are
stored in memory indefinitely (unless the receiver is
unplugged for about one week). You can change a
customized sound field any time by making new
adjustments to the parameters.
See the table on page 20 for adjustable parameters for
each sound field.
Adjusting the volume of the rear and centre
speakers (REAR/CENTER)
If you feel the volume of the rear or centre speaker is

Glossary
Surround sound
Sound that consists of three elements: direct
sound, early reflected sound (early
reflections) and reverberative sound
(reverberation). The acoustics where you hear
the sound affect the way these three sound
elements are heard. These sound elements are
combined in such a way that you can actually
feel the size and the type of a concert hall.
• 3 STEREO mode
Select NORMAL mode if you have front
and rear speakers and a small centre
speaker. Since a small speaker cannot
produce enough bass, the bass sound of
the centre channel is output from the front
speakers.

Select 3 STEREO mode if you have front
and centre speakers but no rear speaker.

without using rear speakers.

As one method of decoding Dolby Surround,
Dolby Pro Logic Surround produces four
channels from two-channel sound. Compared
with the former Dolby Surround system,
Dolby Pro Logic Surround reproduces left-toright panning more naturally and localizes
sounds more precisely. To take full
advantage of Dolby Pro Logic Surround, you
should have one pair of rear speakers and a
centre speaker. The rear speakers output
monaural sound.

• PHANTOM mode
Select PHANTOM mode if you have front
and rear speakers but no centre speaker.
The sound of the centre channel is output
from the front speakers.

This sound format for movie theaters is more
advanced than Dolby Pro Logic Surround. In
this format, the rear speakers output stereo
sound with an expanded frequency range
and a subwoofer channel for deep bass is
independently provided. This format is also
called “5.1” because the subwoofer channel is
counted as 0.1 channel (since it functions only
when a deep bass effect is needed). All six
channels in this format are recorded
separately to realize superior channel
separation. Furthermore, since all the signals
are processed digitally, less signal
degradation occurs. The name “AC-3” comes
from the fact that it is the third audio coding
method to be developed by the Dolby
Laboratories Licensing Corporation.
5.1 CH/DVD jacks
Centre mode
Setting of speakers to enhance Dolby Pro
Logic Surround mode. To obtain the best
possible surround sound, select one of the
following four centre modes according to
your speaker system.
Time lag between the surround sound output
from front speakers and rear speakers. By
adjusting the delay time of the rear speakers,
you can obtain the feeling of presence. Make
the delay time longer when you have placed
the rear speakers in a small room or close to
your listening position, and make it shorter
when you have placed them in a large room
or apart from your listening position.

These jacks are used to input decoded Dolby
Digital (AC-3) audio signals, allowing you to
enjoy 5.1 channel surround sound. Use these
jacks to connect a Dolby Digital (AC-3)
decoder or a DVD player with a built-in AC-3
decoder.
Preset station
A radio broadcasting station that is stored in
memory of the receiver. Once you “preset”
stations, you no longer have to tune in the
stations. Each preset station is assigned its
own preset number, which lets you tune
them in quickly.
