Additional Information
Learning More about This System
Introduction (see pages 1 to 2)
Playable Disc Types:
• About audio format
– Linear PCM: Uncompressed digital audio, the same
format used for CDs and most studio masters.
– Dolby Digital: Compressed digital audio, developed by
Dolby Laboratories, which enables multi-channel
encode to create realistic surround sound.
– DTS (Digital Theater Systems): Compressed digital
audio, developed by Digital Theater Systems, Inc., which
enables multi-channel like Dolby Digital. As the
compression ratio is lower than for Dolby Digital, it
provides wider dynamic range and better separation.
• If you use a DVD-RAM with a cartridge, take the disc out
of the cartridge before inserting.
Daily Operations—Playback (see pages 7 to 11)
Listening to the Radio:
• If you store a new station into an occupied preset number,
the previously stored station in that number will be erased.
• When you unplug the AC power cord or if a power failure
occurs, the preset stations will be erased in a few days. If
this happens, preset the stations again.
Playing Back a Disc:
• On some DVD, SVCD, or VCD discs, the actual operations
may be different from what is explained in this manual, due
to the programming and disc structure; such differences are
not a malfunction of this System.
• When playing back a DVD Audio disc recorded in MLP
(Meridian Lossless Packing; a lossless audio compression
system that can completely recreate the PCM signal), the
signals are recognized as the linear PCM signals, however,
no indicator lights up on the display.
• This System can recognize up to 4 000 files in a disc. Also,
the System can recognize up to 150 files per group and up
to 99 groups in a disc.
– If there are any unplayable files in a folder, those files are
also counted in the total file number.
– Playable files which do not belong to any groups are
handled as Group 1.
• For MP3/WMA playback...
– MP3/WMA discs require a longer readout time than
regular CDs. (It depends on the complexity of the group/
file configuration.)
– Some MP3/WMA files cannot be played back and will
be skipped. This results from their recording processes
and conditions.
– When making MP3/WMA discs, use ISO 9660 Level 1
or Level 2 for the disc format.
– This System can play back MP3/WMA files with the
extension code <.mp3> or <.wma> (regardless of the
letter case—upper/lower).
– It is recommended that you make each MP3/WMA file at
a sampling rate of 44.1 kHz and at bit rate of 128 kbps.
This System cannot play back files made at bit rate of less
than 64 kbps.
Daily Operations—Sound & Other Adjustments
(see pages 12 to 16)
Reinforcing the Bass Sound:
• The adjustment for the subwoofer level does not affect the
sound through the headphones.
Creating Your Own Sound Modes—User Mode:
• When you unplug the AC power cord or if a power failure
occurs, the User Mode settings will be erased in a few days.
If this happens, set the User Modes again.
Selecting the Surround Modes:
• Dolby Pro Logic II Modes: Dolby Pro Logic II Mode is a
multichannel playback format to decode 2-channel sources
into 5.1 channels. Dolby Pro Logic II reproduces spacious
sound from original sound without adding any new sounds
or tonal colorations.
• While you use the headphones, the Surround Mode is
canceled temporarily (“STEREO” appears) and you cannot
use SURROUND MODE and EFFECT.
• Some DVD Audio discs prohibit downmix. While playing
back such a disc...
– You cannot change the Surround Mode. (“MULTI CH”
appears on the display.)
– The System plays back the left front and right front
signals when you have selected “STEREO” for the
Surround Mode or when you use the headphones. (“LR
ONLY” appears on the display.)
Changing the Scanning Mode:
• You cannot change the scanning mode to progressive in the
following cases:
– When your TV does not support the progressive video
input.
– When you have not connected your TV to the unit using
a component video cord.
Setting the Clock:
• “AM 12:00” will flash on the display until you set the
clock.
• The clock may gain or lose 1 to 2 minutes per month. If this
happens, reset the clock.
