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 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.

• If you use a DVD-RAM with a cartridge, take the disc out

of the cartridge before inserting.

Daily Operations—Playback

(see pages 9 to 13)

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.

• 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 14 to 18)

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

multichannel playback format to decode 2-channel sources

into 5.1-channel. Dolby Pro Logic II enables to reproduce

spacious sound from original sound without adding any

new sounds and 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 Audios 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 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 rolls over upward and downward

rapidly.

• 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.
