Dolby Digital	1.0 - 7.1+	Discrete	Audio codec which allows for higher
Plus			bitrates, 7.1 channels or more
			(currently limited by HD DVD,
			Blu-ray disc™ standards), while still
			remaining compatible with older
			5.1 systems. The codec was designed
			based on Dolby Digital but provides
			the necessary versatility going into the
			future.
Dolby TrueHD	1.0 - 7.1+	Discrete	This is a true next-generation
			surround mode where the audio
			is bit-for-bit identical to the high-
			resolution studio master audio.
			Similarly to Dolby Digital Plus
			the track contains a 5.1 core for
			backwards compatibility.
DTS-HD	5.1 - 7.1	Discrete	This is a bit-for-bit identical copy
Master Audio			of the studio master track on your
			media, and therefore produces the
			best possible reproduction. Master
			Audio still contains the DTS core to
			remain backwards compatible with
			older DTS systems.
DTS-HD	5.1 - 7.1	Discrete	This is used when there is not
High Resolution			enough space on the disc to hold the
Audio			complete Master Audio track. Though
			not a bit-for-bit representation, High
			Resolution Audio provides increased
			bitrates while still providing the DTS
			core for backwards compatibility with
			older systems.

The first thing the SSP-800 Surround Sound Processor does is recover the various channels delivered by your source with accuracy and fidelity. This might be a single-channel mono signal, a Dolby Digital Surround EX soundtrack with

6.1channels, or anything in between. The signal may have been delivered via

satellite receiver, cable set-top box, DVD, or even downloaded from the Internet.

Once the SSP-800 has decoded the selected signal, you can then choose to send it to the output unchanged, or you can add further processing, often called post- processing. This kind of processing is particularly useful for utilizing additional surround speakers with limited audio track sources. For instance, processing a

2-channel stereo source with Dolby Pro Logic IIx generates a 7.1-channel output so that you can enjoy the audio source in full surround sound.
