About discs
Playable and non-playable disc types are as follows:
The DVD Logo is a trademark.
• CD-R and CD-RW discs recorded in the SVCD, Video
CD, Audio CD, MP3 or JPEG format can be played
back. However, some discs may not be played back
because of the disc characteristics or recording
conditions.
Note that unfinalized discs cannot be played back.
• DVD-R discs recorded with the DVD VIDEO format can
be played back. However, some discs may not be
played back because of the disc characteristics or
recording conditions.
Note that unfinalized disc cannot be played back.
• DVD VIDEO players and DVD VIDEO discs have their
own Region Code numbers. This unit can play back
only DVD VIDEO discs whose Region Code numbers
include "2."
Examples of playable DVD VIDEO discs:
The unit is compatible with the PAL and NTSC systems,
and can play back discs whose Region Code numbers
include number "2." You can select "NTSC" or "PAL"
while using the NTSC/REMOTE/PAL switch on the rear

• Playing back discs listed as "Non-playable discs" above
may generate noise and damage speakers.
• This unit can play back audio signals recorded in CD-G,
CD-EXTRA, CD-TEXT and MIX-MODE CD discs.
Some audio formats used on discs are described below.
• Linear PCM
Uncompressed digital audio, the same format used on
CDs and most studio masters.
DVD AUDIO supports up to six channels at sample
rates of 48/96/192 kHz (also 44.1/88.2/176.4 kHz) and
sample sizes of 16/20/24 bits.
DVD VIDEO supports two channels at sampling rates
of 48/96 kHz and quantization of 16/20/24 bits.
Audio CD/Video CD limited to two channels, 44.1 kHz
at 16 bits.
• MPEG Multichannel
A surround audio format which can handle the
augmentative 7.1-channel format (rare for home use),
as well as 5.1-channel.
• Dolby Digital
A surround audio format configured with six channels.
Because the "LFE (Low-Frequency Effect for sub-
woofer, etc.)" channel, one of the six channels, is an
auxiliary channel, this format is called "5.1-channel
system."
Not all Dolby Digital discs contain six (5.1) channel
information.
• DTS (Digital Theater Systems)
A surround audio format configured with six (5.1)
channels which is same as Dolby Digital. Because the
compression ratio is lower than Dolby Digital, it
provides wider dynamic range and better separation.
Not all DTS discs contain six (5.1) channels
information.
• MLP (Meridian Lossless Packing)
A format for DVD AUDIO with the compression ratio of
about 2:1 while allowing the PCM signal to be
completely recreated by the MLP decoder (required in
all DVD AUDIO players). It supports up to 192 kHz/24
bit.
The associated indicator lights up in the display window
when playing back a disc.
* When playing back a DVD AUDIO disc recorded by
MLP (Meridian Lossless Packing; a lossless audio
compression system that can completely recreate the
PCM signal), no indicator lights up in the display
window.
Note that with some formats and/or depending on the
unit’s [DIGITAL AUDIO OUTPUT] setting, digital audio
signals may not be always transmitted from the unit’s
DIGITAL OUT jacks as they are recorded on the disc.
See [DIGITAL AUDIO OUTPUT] on page 60 for details.
