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.
• Some DVD Audios prohibit downmix. When you play
back such a disc, “LR ONLY” appears on the display and
the System plays back the left front and right front signals.
• 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.
• 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/JPEG/ASF 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 15)
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.
Creating 3-dimensional Sound Field—3D Phonic:
• While you use the headphones, 3D Phonic is canceled
temporary.
• 3D Phonic is also applied to the optical digital output
signals through the OPTICAL DIGITAL OUTPUT
terminal.
Changing the Color System and Scanning Mode:
• If you play back an NTSC disc with the color system set to
“PAL (PROG),” the disc will be reproduced using “PAL
60” format, however, if the TV does not support this
format, the screen may not display properly.
• If you play back a PAL disc with the color system set to
“NTSC (PROG),” you can watch the playback pictures, but
the following symptoms may occur:
– The items on the disc menu will be blurred, and be shown
slightly shifted when highlighted.
– The aspect ratio of the picture may differ from the
original aspect ratio.
– The picture movement is not smooth.
• 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.
• When you play back an NTSC disc in progressive scanning
mode, the System outputs the NTSC signal regardless of
the color system settings.
Setting the Clock:
• “0:00” 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.
Unique DVD/VCD Operations (see pages 16 to 18)
Selecting the Sound Track:
• On some DVD Video discs, you cannot change audio
languages while playing back.
Playing Back Bonus Group:
• You cannot select a track in the bonus group for Program
Play.
Special Picture Playback:
• During slow-motion playback, no sound will be
reproduced.
• While zoomed in, the picture may look coarse.
