ABOUT THE DISCS WHICH CAN BE
PLAYED BY THIS UNIT
This unit can play the following 4 kinds of discs.
(As seen with the label surface facing up)
1. Super Audio CDs (single-layer discs)
Super Audio CDs feature a 2-layer construction, and the layer on
which the Super Audio CD signals are recorded is called the high-
density (HD) layer. Only Super Audio CD signals are recorded on
2. Super Audio CDs (dual-layer discs)
These discs have two HD layers to enable prolonged playback. They
are made with a semi-transparent film so that both layers can be
played without having to flip the disc over. Switching between the two
playback layers is done automatically.
3. CD/CD-R/CD-RW discs (recorded in the CD-DA format)
(Conventional music CDs)
These are the music CDs available in stores today.
4. Hybrid discs (Super Audio CD + CD)
These feature a combination of the CD layer of conventional discs and
one HD layer of the Super Audio CDs.
When one of these discs is read by this unit, priority is given to playing
the HD layer of the Super Audio CD. To play the CD layer, switch over
to this layer by pressing the
button on the main unit or on
the remote control unit while the unit has stopped operating.
The glossy side shining like a rainbow is the front side of the disc, and
the side on which the label is printed is the back.
Unlike conventional turntables for playing analog discs, the SA-1 Super
Audio CD Player reads the information recorded on the disc from
underneath without contacting it using a beam of laser light. Therefore,
the performance of a compact disc will not degrade like conventional
