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:

• 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.
