Super Audio CD
A Super Audio CD disc can reproduce sounds
that are extremely faithful to the original sound
by use of DSD (Direct Stream Digital)
technology. This technology utilizes a sampling
frequency of 2.8224 MHz, which is 64 times that
of a conventional CD, and 1-bit quantization that
enables the disc to hold 4 times the amount of
information that a standard PCM format CD can
hold. Super Audio CDs are divided into the
following types.
• Super Audio CD (single layer disc)
This disc consists of a single HD layer*.
* High density signal layer for the Super Audio CD
• Super Audio CD (dual layer disc)
This disc consists of dual HD layers and is
capable of extended play over long periods.
Also, as the dual layer disc consists of dual HD
layers on one side only, you do not have to turn
the disc over during playback.
• Super Audio CD + CD (Hybrid disc)
This disc consists of an HD layer and a CD
layer. Also, as the dual layers are on one side
only, you do not have to turn the disc over
during playback. You can play this CD layer
using a conventional CD player.

Title
The longest section of a picture or music feature
on a DVD, movie, etc., in video software, or the
entire album in audio software.
Track
Section of a picture or a music piece on a Super
Audio CD, CD, VIDEO CD or MP3. An album
is composed of several tracks (MP3 only).
VIDEO CD
A compact disc that contains moving pictures.
The picture data uses the MPEG 1 format, a
worldwide standard of digital compression
technology. The picture data is compressed to
about 1/140 of its original size. Consequently, a
12 cm VIDEO CD can contain up to 74 minutes
of moving pictures.
VIDEO CDs also contain compact audio data.
Sounds outside the range of human hearing are
compressed while sounds we can hear are not
compressed. VIDEO CDs can hold 6 times the
audio information of conventional audio CDs.
There are 2 versions of VIDEO CDs.
• Version 1.1: You can play only moving
pictures and sounds.
• Version 2.0: You can play high-resolution still
pictures and enjoy PBC functions.
This receiver conforms to both versions.
