Super Audio CD

The Super Audio standard is based on Direct Stream Digital (DSD) technology. This new direct-stream digital format comprises a 1-bit system that has a digital sampling frequency that is 64 times higher than that of conventional audio CD. The results are spectacular: a frequency response of over 50k Hz and a 120 dB dynamic range over the entire audible spectrum. Mixed with as many of the original frequencies as possible, the audio information audible for human ears sounds much more natural.

All audible frequencies are, after all, embedded in the frequency range as emitted by the sound source. A better reproduction does not exist! For the first time your ears will relive reality.

The next standard: hybrid disc

The Super Audio CD is the evolution of the CD that provides ultra-high-quality sound. Additional features, including multi-channel, can be offered. On the high density (HD) Super Audio CD you may have access to separate areas, containing two-channel stereo and multi- channel.

But that is not all! The hybrid version of the SACD guarantees backward compatibility with the installed base of CD and DVD players. In addition to the HD layer, the hybrid disc contains a standard density CD layer with conventional two-channel stereo CD audio information. The two layers are read from the same side of the disc. The HD layer is read by a DVD laser. The bottom reflective layer with conventional CD sound is read by the CD laser through the second, semi-transmissive HD layer.

	SA-12S1:
	reality in sound... and vision		English
	The SA-12S1 will not only surprise you with its superior

	reproduction of almost all existing audio formats.
	Connected to your TV, your SA-12S1 presents VCD and
	DVD video information as perfect digital studio-quality
	images with truly 3-dimensional digital multi-channel
	audio. Story sequences can be screened from your own
	choice of camera angle. You can break down language
	barriers with sound tracks in as many as eight languages,
	plus - if available on disc - as many as 16 subtitling
	languages. Video becomes a new experience. That makes
	the SA-12S1 an essential component in a state-of-the-art
	audio-video system.
	Super Audio CD
	You will recognize Super Audio CDs
	by the logo. There are three types of
	Super Audio CDs: single-layer, dual-
	layer and hybrid discs. Each type may
	contain two areas of recorded information: a High
	Quality Stereo area and a High Quality Multi-channel
	area.
	- The single layer disc may contain both information
	areas.
	- The dual layer disc may contain both information areas
	but a double amount of information can be stored on
	the disc thanks to the second layer.
	- The hybrid disc may contain not only both information
	areas but also a second, standard CD layer, making it
	playable on standard CD players.
	Recorded information may vary per area. This is
	indicated in the disc inlay. Areas can be selected
	separately before or during playback. When playing
	Super Audio CDs, the player can be operated via the
	keys on the player front and the remote control or via
	the On-Screen Display on your TV.
