Features
Playback of the Super Audio CD recorded
in the DSD format
The DSD (Direct Stream Digital) format is the core
technology of a Super Audio CD, allowing music
reproduction that is extremely faithful to the original
sound.
The DSD format, using a 2.8224 MHz sampling frequency
64 times higher than that of a conventional CD, and the 1-
bit quantization, makes possible recording of more than
four times the data information of the PCM format which
is used for a conventional CD.
Different from the PCM format which performs data
decimation and interpolation via digital filters, the DSD
format adopts the simple playback process. In other
words, the A/D converted 1-bit digital signal only passes
through an analog low-pass filter before playback.
As a whole, the DSD format achieves both a wide
frequency range of, theoretically, over 100 kHz, and a
wide dynamic range across the audible frequency range
resulting in high-quality music reproduction faithful to
the original sound.
To play back a Super Audio CD recorded in the DSD
format with exceptional quality, the SCD-XB940 employs
a newly developed DSD decoder and a D/A converter
system, as well as a chassis and loading mechanism
especially designed for this unit.
Playback of a conventional CD with
higher quality
The SCD-XB940 can also play back a conventional CD
with higher quality than a conventional CD player. To
provide enhanced quality, the SCD-XB940 employs
various advanced technologies. For example, a 24-bit
precision variable coefficient (V.C.) digital filter is
provided for CD playback (see page 18). By selecting one
of five filters which have different cutoff characteristics,
you can adjust the tone quality in accordance with the
music source or your audio system.
Others
• A Super Audio CD can mark up to 255 track/index
numbers. This feature applies to SCD-XB940.
• The supplied remote is capable of controlling either the
SCD-XB940 and a conventional Sony CD player.

Provides well-balanced natural sound, with a large scale
feel and rich reverberation.
Suitable for listening to any kind of music when you are
relaxed.
4: Silky (slow roll-off)
Provides a wide scale feel with associated subtleties.
Suitable for light classical music, especially strings.
What is a variable coefficient (V.C.) digital
filter?
CD players use digital filters to eliminate the noise
generated during sampling. You can change the tone of
your music by changing the cutoff characteristics of the
digital filter.
Sharp roll-off and slow roll-off
Digital filters can be roughly classified into sharp roll-off
types and slow roll-off types, according to their cutoff
characteristics.
Sharp roll-off filters quickly cut off noise over 22.05 kHz
generated during sampling. This is a superior way of
completely reproducing signals below 20 kHz and is the
basic principle behind digital audio.
On the other hand, slow roll-off filters cut off noise
generated during sampling, and are able to hold pre-
ringing and post-ringing (a kind of sound smearing) in
the impulse response signal to a minimum.
Note
The Digital Filter function primarily changes characteristics
outside the audible frequency. They cannot affect changes within
the audible frequency such as those provided by the tone controls
of the amplifier. Therefore, with certain combinations of
hardware and software, there may be no noticeable effect after
switching the filter.

Additional
Information
This chapter provides additional
information that will help you
understand and maintain your Super
Audio CD player.
Precautions
On safety
• Caution — The use of optical instruments with this product
will increase eye hazard.
• Should any solid object or liquid fall into the cabinet, unplug
the player and have it checked by qualified personnel before
operating it any further.
On power sources
• Before operating the player, check that the operating voltage of
the player is identical with your local power supply. The
operating voltage is indicated on the nameplate at the rear of
the player.
• The player is not disconnected from the mains as long as it is
attached to the mains, even if the player itself has been turned
off.
• If you are not going to use the player for a long time, be sure to
disconnect the player from the mains. To disconnect the mains
lead, grasp the plug itself; never pull the cord.
On placement
• Place the player in a location with adequate ventilation to
prevent heat build-up in the player.
• Do not place the player on a soft surface such as a rug that
might block the ventilation holes on the bottom.
• Do not place the player in a location near heat sources, or in a
place subject to direct sunlight, excessive dust or mechanical
shock.
On avoiding deterioration of sound quality
• Do not touch the lens inside.
On operation
• If the player is brought directly from a cold to a warm location,
or is placed in a very damp room, moisture may condense on
the lenses inside the player. Should this occur, the player may
not operate properly. In this case, remove the disc and leave
the player turned on for about an hour until the moisture
evaporates.
• During power on, some noise may be heard while the disc is
being loaded into the Super Audio CD player. This is not a
malfunction.
On adjusting the volume
• Do not turn up the volume too much while listening to a
portion with very low level inputs or no audio signals. If you
do, the speakers may be damaged when a peak level portion is
played.
On inserting a disc
• You may hear a transmission or a mechanical sound from the
player. This indicates that the player is automatically adjusting
its internal mechanisms according to the inserted disc.
You may also hear the mechanical sound from the player when
you insert a warped disc.
