Learning More about This System
Before Operating the System
(see pages 8 to 11)
Playable Disc Types:
• If you play back an NTSC disc with this setting set to 
“PAL,” you can watch the playback pictures (the disc will 
be reproduced using “PAL 60” format), but the TV screen 
may roll over upward and downward rapidly.
• If you play back a PAL disc with this setting set to 
“NTSC,” 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.
• 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 the 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.
– 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), the signals recognized as the linear PCM 
signal, however, no indicator lights up in the display 
window.
Daily Operations—Playback 
(see pages 12 to 16)
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.
• For MP3/WMA/JPEG playback...
– MP3/WMA/JPEG discs are required a longer readout 
time than regular CDs. (It depends on the complexity of 
the group/file configuration.)
– Some MP3/WMA/JPEG 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/JPEG files with 
the extension code <.mp3>, <.wma> or <.jpg> 
(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.
• When discs* in more than one tray are loaded on the disc 
trays, they are played in sequence as follows:
Ex.:When DISC 2 is pressed:
DISC 2]
DISC 3]
DISC 4]
DISC 5]
DISC 1
(then stops)
* When no disc is loaded on the tray, that disc number is 
skipped.
Daily Operations—Sound&Other Adjustments 
(see pages 17 to 20)
Adjusting the Volume:
• Be sure to turn down the volume before connecting or 
putting the headphones.
Reinforcing the Bass Sound:
• RHYTHM AX function also affects the sound through the 
headphones.
• While listening with the headphones, you cannot adjust the 
subwoofer level.
• RHYTHM AX function and subwoofer level setting does 
not affect recording.
• You can adjust the subwoofer level while RHYTHM AX 
is on.
• The subwoofer lamp changes brightness according to the 
subwoofer level.
Selecting the Sound Modes:
• The sound mode lamp and Surround mode lamp change 
brightness according to selecting Sound mode.
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 3D PHONIC Mode:
• While you use the headphones, 3D PHONIC mode is 
canceled temporary.
• 3D PHONIC setting is also applied to the optical digital 
output signals through the OPTICAL DIGITAL OUTPUT 
terminal.
