recorded.
Notes
 When you set the item to “AUTO,” the language may 
change. The “TRACK SELECTION” setting has 
higher priority than the “AUDIO” settings in 
“LANGUAGE SETUP” (page 59).
 If PCM, DTS, MPEG audio, and Dolby Digital sound 
tracks have the same number of channels, the system 
selects PCM, DTS, Dolby Digital, and MPEG audio 
sound tracks in this order.
 Depending on the DVD, the audio channel with 
priority may be predetermined. In this case, you 
cannot give priority to the DTS, Dolby Digital, or 
MPEG audio format by selecting “AUTO.”

Set priority data you want to play, when you 
play the DATA CD (CD-ROM/CD-R/CD-RW) 
contained MP3 audio tracks and JPEG image 
files.
Note
When you play Multi Session CDs, the system decides 
a target to play for last session or session linked with 
last session.

To obtain the best possible surround sound, set 
the size of the speakers you have connected and 
their distance from your listening position. Then 
use the test tone to adjust the level and the 
balance of the speakers to the same level.
Select “SPEAKER SETUP” in the setup 
display. For details, see “Using the Setup 
Display” (page 58).
The default settings are underlined.

 When you select an item, the sound cuts off for a 
moment.
 Depending on the settings of other speakers, the 
subwoofer may output excessive sound.
xDISTANCE
The default distance setting for the speakers in 
relation to the listening position is shown below.
Be sure to change the value in the Setup Display 
when you move the speakers.
Notes
 In SPEAKER SETUP, the North American model’s 
OSD displays both metric and imperial 
measurements. The other model displays metric 
measurements only. The manual shows both.
 When you set the distance, the sound cuts off for a 
moment.
 If all front and surround speakers are not placed at an 
equal distance from your listening position, set the 
distance according to the closest speaker.
 Do not place the surround speakers farther away from 
your listening position than the front speakers.
 The DISTANCE setting is available except for Super 
Audio CDs.

If you experience any of the following 
difficulties while using the system, use this 
troubleshooting guide to help remedy the 
problem before requesting repairs. Should any 
problem persist, consult your nearest Sony 
dealer.
Power
The power is not turned on.
 Check that the AC power cord is connected 
securely.
When the STANDBY indicator flashes
Immediately unplug the power cord and check the 
following items.
 Is the voltage selector set to the correct voltage? 
Check the voltage selector for your region, then 
make sure the voltage selector is set correctly.
 Are the + and – speaker cords short-circuited?
 Are you using only the specified speakers?
 Is anything blocking the ventilation holes on the 
top of the system?
After checking the above items and fixing any 
problems, connect the power cord again and turn on 
the system. If the indicator still flashes, or if the 
cause of the problem cannot be found even after 
checking all the above items, consult your nearest 
Sony dealer.

could affect picture quality. If you still experience 
problems even when you connect your system 
directly to your TV, try connecting your system to 
your TV’s S video input (page 17).
 Except for the Pan American and European 
model, the colour system is different. Set the

Album
Section of a music piece or an image on a data 
CD containing MP3 audio tracks or JPEG files.
Chapter
Subdivision of a title on a DVD. A title is 
composed of several chapters.
Dolby Digital
This sound format for movie theatres is more 
advanced than Dolby Surround Pro Logic. In 
this format, the surround 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.
Dolby Surround Pro Logic
As one method of decoding Dolby Surround, 
Dolby Surround Pro Logic produces four 
channels from two-channel sound. Compared 
with the former Dolby Surround system, Dolby 
Surround Pro Logic reproduces left-to-right 
panning more naturally and localizes sounds 
more precisely. To take full advantage of Dolby 
Surround Pro Logic, you should have one pair of 
surround speakers and a center speaker. The 
surround speakers output monaural sound.
Dolby Pro Logic II 
Dolby Pro Logic II creates five full-bandwidth 
output channels from two-channel sources. This 
is done using an advanced, high-purity matrix 
surround decoder that extracts the spatial 
properties of the original recording without 
adding any new sounds or tonal colorations.
xMovie mode
The Movie mode is for use with stereo television 
shows and all programs encoded in Dolby 
Surround. The result is enhanced soundfield 
directionality that approaches the quality of 
discrete 5.1-channel sound.
Glossary

							70GB
xMusic mode
The Music mode is for use with any stereo music 
recordings, and provides a wide and deep sound 
space.
DTS
Digital audio compression technology that the 
Digital Theater Systems, Inc. developed. This 
technology conforms to 5.1-channel surround. 
The rear channel is stereo and there is discrete 
subwoofer channel in this format. DTS provides 
the same 5.1 discrete channels of high quality 
digital audio. The good channel separation is 
realized because the all channel data is recorded 
discrete and processed in digital.
DVD
A disc that contains up to 8 hours of moving 
pictures even though its diameter is the same as 
a CD.
The data capacity of a single-layer and single-
sided DVD, at 4.7 GB (Giga Byte), is 7 times 
that of a CD. Furthermore, the data capacity of a 
dual-layer and single-sided DVD is 8.5 GB, a 
single-layer and double-sided DVD 9.4 GB, and 
a dual-layer and double-sided DVD 17 GB.
The picture data uses the MPEG 2 format, one of 
the worldwide standards of digital compression 
technology. The picture data is compressed to 
about 1/40 of its original size. The DVD also 
uses the variable rate coding technology that 
changes the data to be allocated according to the 
status of the picture.
The audio data is recorded in Dolby Digital as 
well as in PCM, allowing you to enjoy more 
realistic audio presence.
Furthermore, various advanced functions such 
as the multi-angle, multilingual, and Parental 
Control functions are provided with the DVD.
File
Section of a picture on a data CD containing 
JPEG image files.
Film based software, Video based 
software
DVDs can be classified as Film based or Video 
based software. Film based DVDs contain the 
same images (24 frames per second) that are 
shown at movie theatres. Video based DVDs, 
such as television dramas or sit-coms, displays 
images at 30 frames (or 60 fields) per second.
Interlace format
Interlace format shows every other line of an 
image as a single “field” and is the standard 
method for displaying images on television. The 
even number field shows the even numbered 
lines of an image, and the odd numbered field 
shows the odd numbered lines of an image.
Multi-angle function
Various angles, or viewpoints of the video 
camera, for a scene are recorded on some DVDs.
Multilingual function
Several languages for the sound or subtitles in a 
picture are recorded on some DVDs.
Parental Control
A function of the DVD to limit playback of the 
disc by the age of the users according to the 
limitation level in each country. The limitation 
varies from disc to disc; when it is activated, 
playback is completely prohibited, violent 
scenes are skipped or replaced with other scenes 
and so on.
Playback Control (PBC)
Signals encoded on VIDEO CDs (Version 2.0) 
to control playback.
By using menu screens recorded on VIDEO 
CDs with PBC functions, you can enjoy playing 
simple interactive programs, programs with 
search functions, and so on.
Progressive format
Compared to the Interlace format that alternately 
shows every other line of an image (field) to 
create one frame, the Progressive format shows 
the entire image at once as a single frame. This 
means that while the Interlace format can show 
30 frames (60 fields) in one second, the 
Progressive format can show 60 frames in one 
second. The overall picture quality increases and 
still images, text, and horizontal lines appear 
sharper. This system is compatible with the 480 
progressive format.
