ABOUT SUPER AUDIO

Super Audio CD is the next-generation audio disc format. It has been jointly developed and standardized by Sony and Phillips of the Nether- lands which are CD licensers. Compared with the Pulse Code Modula- tion (PCM) system used for digital audio recording as typified by conventional CDs, the Super Audio CDs are recorded using the Direct Stream Digital (DSD) system which has about 4 times more information per unit time. The system theoretically achieves a dynamic range of 120 dB within the audible frequency band and a wide playback frequency band that exceeds 100 kHz. It is capable of recording a maximum of 255 programs for up to 109 minutes.

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 single-layer discs.

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.

COMPACT DISCS

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 analog records.

Handle discs carefully so as not to damage or scratch the front side. To protect the disc, avoid placing it in the following locations:

–In direct sunlight or near a source of heat like a heater.

–In a place which is damp or dirty.

–In a place which could be exposed to rain, such as near a window.

Always keep the disc surface clean.

Up to six billion data units are recorded on the front side of the disc. When cleaning the disc surface, always be sure to use a special compact disc cleaner and wipe as shown below.

Wipe in a radial direction. Do not wipe in circumferential direction.

•Do not use conventional record cleaner for analog records, as this will adversely affect the disc surface.

Store discs properly by placing them in their disc cases.

•Do not attach a piece of paper or sticker on the label side of disc. When a disc has a piece of plastic tape or rental CD label with paste protruded from the edge or when a disc has a trace of such a sticky object, do not attempt to play the disc. If such a disc is played on the CD player, impossibility of taking out the disc or other malfunction may result.

•Do not use a disc with a special shape.

Do not attempt to play a disc with a special shape such as a heart- shaped disc or octagonal disc. Otherwise the equipment malfunction may result.
