GENERAL DESCRIPTION
This data sheet describes the 104 ROM-code version of
the SAA7710T chip. The SAA7710T chip is a high quality
audio-performance digital add-on processor for digital
sound systems. It provides all the necessary features for
complete Dolby Pro Logic surround sound on chip.
In addition to the Dolby Pro Logic surround function, this
device also incorporates a 5-band parametric equalizer, a
tone control section and a volume control. Instead of Dolby
Pro Logic surround, the Hall/matrix surround and
Incredible sound functions can be used together with the
equalizer or tone control.
