tments
• REAR
* Rear speaker position
Correctly specify the location of the rear speakers to 
enjoy the surround effect.
• Set to “SIDE,” if the location of the rear speakers 
corresponds to section A below.
• Set to “REAR,” if the location of the rear speakers 
corresponds to section B below.
This setting affects only “VIRTUAL REAR 
SHIFT,” “VIRTUAL MULTI REAR,” and 
“VIRTUAL MULTI DIMENSION” mode 
(page 54). This setting does not affect the Super 
Audio CD Multi audio signals.
• SUBWOOFER
Notes
• The cut off frequency for the subwoofer is fixed at 
120 Hz.
• If your speakers are too small to reproduce low 
bass frequencies, utilize a subwoofer for low 
frequency sound. When you set the speaker 
settings to “SMALL,” the bass redirection 
circuitry will be activated and the bass 
frequencies for the speakers are output from the 
subwoofer.
• Even if there are fewer than 6 speakers connected, 
the player distributes the audio signal components 
to the front speakers.
◆ DISTANCE

to the speakers. 
Set the distance to your front speakers in 
“FRONT” first (A). Then adjust the values in 
“CENTER” (center speaker B), and 
“REAR” (rear speaker C) to reflect the 
actual distance to your center speaker, and 
rear speakers.
Be sure to change the value in the Setup 
Display each time you move the speakers. 
Start from the front speaker. The default 
adjustments are in parentheses.
LARGE
(REAR/SIDE): Normally select 
this position. Select according

Glossary
Album (page 61, 63)
A unit in which to store JPEG image files or 
MP3 audio tracks on a DATA CD. (“Album” 
is an exclusive definition for this player.)
Chapter (page 12)
Sections of a picture or a music feature that 
are smaller than titles. A title is composed of 
several chapters. Depending on the disc, no 
chapters may be recorded.
Dolby Digital (page 23, 81)
Digital audio compression technology 
developed by Dolby Laboratories. This 
technology conforms to multi-channel 
surround sound. The rear channel is stereo 
and there is a discrete subwoofer channel in 
this format. Dolby Digital provides the same 
discrete channels of high quality digital audio 
found in “Dolby Digital” theater surround 
sound systems. Good channel separation is 
realized because all of the channel data is 
recorded discretely and little deterioration is 
realized because all channel data processing 
is digital. 
Dolby Surround (Pro Logic) (page 23)
Audio signal processing technology that 
Dolby Laboratories developed for surround 
sound. When the input signal contains a 
surround component, the Pro Logic process 
outputs the front, center and rear signals. The 
rear channel is monaural.

DTS (page 23, 82)
Digital audio compression technology that 
Digital Theater Systems, Inc. developed. This 
technology conforms to multi-channel 
surround sound. The rear channel is stereo 
and there is a discrete subwoofer channel in 
this format. DTS provides the same discrete 
channels of high quality digital audio.
Good channel separation is realized because 
all of the channel data is recorded discretely 
and little deterioration is realized because all 
channel data processing is digital.
DVD VIDEO (page 8)
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 is 4.7 GB (Giga Byte), which is 7 
times that of a CD. The data capacity of a 
double-layer and single-sided DVD is 8.5 
GB, a single-layer and double-sided DVD is 
9.4 GB, and double-layer and double-sided 
DVD is 17 GB.
The picture data uses the MPEG 2 format, a 
worldwide standard of digital compression 
technology. The picture data is compressed to 
about 1/40 (average) of its original size. The 
DVD also uses a variable rate coding 
technology that changes the data to be 
allocated according to the status of the 
picture. Audio information is recorded in a 
multi-channel format, such as Dolby Digital, 
allowing you to enjoy a more realistic audio 
presence.
Furthermore, various advanced functions 
such as the multi-angle, multilingual, and 
Parental Control functions are provided with 
the DVD.
DVD-RW (page 8)
A DVD-RW is a recordable and rewritable 
disc that is the same size as a DVD VIDEO. 
The DVD-RW has two different modes: VR 
mode and Video mode. DVD-RWs created in 
Video mode have the same format as a DVD 
VIDEO, while discs created in VR (Video 
Recording) mode allow the contents to be 
programmed or edited.
DVD+RW (page 8)
A DVD+RW (plus RW) is a recordable and 
rewritable disc. DVD+RWs use a recording 
format that is comparable to the DVD VIDEO 
format.
File (page 61, 64)
A JPEG image recorded on a DATA CD 
(“File” is an exclusive definition for this 
player.) A single file consist of a single 
image.
Film based software, Video based 
software (page 21)
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 theaters.
Video based DVDs, such as television 
dramas or sit-coms, displays images at 30 
frames/60 fields (24 frames/50 fields) per 
second.
Normal (Interlace) format (page 21)
Normal (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.
,continued
90
Progressive format (page 21)
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 25 or 30 frames 
(50-60 fields) in one second, the Progressive 
format can show 50-60 frames in one second. 
The overall picture quality increases and still 
images, text, and horizontal lines appear 
sharper. This player is compatible with the 
480 progressive format.
Progressive JPEG
Progressive JPEGs are used mostly on the 
internet. They are different from other JPEGs 
in that they “fade in” gradually instead of 
being drawn from top to bottom when 
displayed on a browser. This lets you view the 
image while it is being downloaded.
Scene (page 12)
On a VIDEO CD with PBC (playback 
control) functions, the menu screens, moving 
pictures and still pictures are divided into 
sections called “scenes.”
Super Audio CD (page 8)
A Super Audio CD disc can reproduce sounds 
that are extremely faithful to the original 
sound by use of DSD (Direct Stream Digital) 
technology. This technology utilizes a 
sampling frequency of 2.8224 MHz, which is 
64 times that of a conventional CD, and 1-bit 
quantization that enables the disc to hold 4 
times the amount of information that a 
standard PCM format CD can hold. Super 
Audio CDs are divided into the following 
types.
• Super Audio CD (single layer disc)
This disc consists of a single HD layer*.
*High density signal layer for the Super Audio CD
• Super Audio CD (dual layer disc)
This disc consists of dual HD layers and is 
capable of extended play over long periods.
Also, as the dual layer disc consists of dual 
HD layers on one side only, you do not have 
to turn the disc over during playback.
• Super Audio CD + CD (Hybrid disc)
This disc consists of an HD layer and a CD 
layer. Also, as the dual layers are on one 
side only, you do not have to turn the disc 
over during playback. You can play the CD 
layer using a conventional CD player.
• 2 channel + Multi-channel Super Audio CD
This disc consists of the 2 channel playback 
area and the multi-channel playback area.
Title (page 12)
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 (page 12)
Sections of a picture or a music feature on a 
VIDEO CD, CD or DATA CD (the length of 
a song). (“Track” in DATA CD is an 
exclusive definition for this player.)
Video Index (VIDEO CD) (page 15)
A number that divides a track into sections to 
easily locate the point you want on a VIDEO 
CD. Depending on the disc, no index may be 
recorded.
