Super Audio CD (SACD)
An SACD 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 2.8224MHz, 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. SACDs are divided
into the following types.
• Super Audio CD (single layer disc)

This disc consists of a single HD layer*.
Press SACD/CD repeatedly so that the SACD indicator
on the player lights up.
* 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.
Press SACD/CD repeatedly so that the SACD indicator
on the player lights up.
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. Press
SACD/CD while the disc is stopped to select the layer
you want to listen to. Also, as the dual layers are on one
side only, you do not have to turn the disc over during
playback. You can play the CD layer using a
conventional CD player.

This Player Can Play the Following Discs

DVD
A DVD disc contains both audio and visual data, and is
either 12 or 8 centimeters in diameter. A 12 centimeter disc
can hold 7 times the amount of data contained in a CD-
ROM, which translates to 4 consecutive hours of playing
time (8 hours for double-sided discs). DVD discs are
divided into 4 types: single sided single layer, single sided
double layer, double sided single layer, and double sided
double layer.

• Single-layer single-sided: Capacity 4.7 GB

• Double-layer single-sided: Capacity 8.5 GB

• Single-layer double-sided: Capacity 9.4 GB

• Double-layer double-sided: Capacity 17 GB
