Super Audio CD is a new high-quality audio
disc standard where music is recorded in the
DSD (Direct Stream Digital) format
(conventional CDs are recorded in the PCM
format). The DSD format, using a sampling
frequency 64 times higher than that of a
conventional CD, and with 1-bit quantization,
achieves both a wide frequency range and a wide
dynamic range across the audible frequency
range, and so provides music reproduction
extremely faithful to the original sound.
Types of Super Audio CDs
There are two types of discs, depending on the
SA-CD layer and CD layer combination.
SA-CD layer: A high-density signal layer for
Super Audio CD
CD layer
1)
:
A layer that is readable by a
conventional CD player
Single layer disc
(a disc with a single SA-CD layer)
Hybrid disc
2)
(a disc with an SA-CD layer and a CD layer)
An SA-CD layer consists of the 2 channel area
or the multi-channel area.
2 channel area: An area in which 2 channel
stereo tracks are recorded
Multi-channel area:
An area in which multi-
channel (up to 5.1 channels)
tracks are recorded
Example:
When the 2 channel area and the multi-channel area
are recorded on an SA-CD layer of a hybrid disc
1)
You can play the CD layer on a conventional CD
player.
2)
Since both layers are on one side, it is not necessary
to turn the disc over.
3)
Press SA-CD/CD to select the layer you want to
listen to (see page 9).
4)
In case of a disc with both areas, press MULTI/2CH
to select the area you want to listen to (see page 10).
