To obtain the best possible surround sound, set 
for the type 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 57).
The default settings are underlined.
To return to the default setting

 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.
 You cannot adjust the size of the speaker, as this 
setting is used for specifying the speaker type.
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
 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.

Album

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 movie theatre sound format 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,” with the subwoofer channel is 
designated as the 0.1 channel (since it functions 
only when a deep bass effect is needed). All six 
channels in this format are recorded separately 
for superior channel separation. Furthermore, 
since all the signals are processed digitally, less 
signal degradation occurs.
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 colourations.
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.
xMusic mode
The Music mode is for use with any stereo music 
recordings, and provides a wide and deep sound 
space.
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.
DTS
Digital audio compression technology 
developed by Digital Theater Systems, Inc. 
developed. This technology conforms to 5.1-
channel surround. This format comprises of 
stereo surround channel and a discrete 
subwoofer channel in this format. DTS provides 
the same 5.1 discrete channels of high quality 
digital audio. Superior channel separation is 
realized due to all channel data being recorded 
discretely and processed digitally.
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 
a worldwide standard of digital compression 
technology. The picture data is compressed to 
about 1/40 of its original size. DVD also uses 
variable rate coding technology that processes 
allocated data 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.
Multi-angle function
Various angles, or viewpoints of the video 
camera, of 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 viewers 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.
Region Code
This system is used to protect copyrights. A 
region number is allocated on each DVD system 
or DVD disc according to the sales region. Each 
region code is shown on the system as well as on 
the disc packaging. The system can play the 
discs that match its region code. The system can 
also play discs with the “ ” mark. Even when 
the region code is not shown on the DVD, the 
region limit may still be activated.
Scene
On a VIDEO CD with PBC (playback control) 
functions, the menu screens, moving pictures 
and still pictures are divided into sections called 
“scenes.”
Title
The longest section of a picture or music feature 
on a DVD, movie, etc., in video software, or the 
entire album in audio software. 
Track
Section of a picture or a music piece on a CD, 
VIDEO CD or MP3. An album is composed of 
several tracks (MP3 only).

							68GB
VIDEO CD
A compact disc that contains moving pictures.
The picture data uses the MPEG 1 format, one of 
a worldwide standard of digital compression 
technology. The picture data is compressed to 
about 1/140 of its original size. Consequently, a 
12 cm VIDEO CD can contain up to 74 minutes 
of moving pictures.
VIDEO CDs also contain compact audio data. 
Sounds outside the range of human hearing are 
compressed while sounds we can hear are not 
compressed. VIDEO CDs can hold 6 times the 
audio information of conventional audio CDs.
There are 2 versions of VIDEO CDs.
 Version 1.1: You can play only moving 
pictures and sounds.
 Version 2.0: You can play high-resolution still 
pictures and enjoy PBC functions.
This system conforms to both versions.
