multichannel

The Audio Video Preamplifier is designed to be flexible with respect to its audio
configurations, as well. In its standard configuration, it provides the standard 5.1
channel selection of outputs made popular by home theater. However, it also in-
cludes an extra two channels that may be used in any of several ways, whether
to accommodate larger rooms (separate side and rear speakers) or more sophisti-
cated audio processing (Dual Drive™ surrounds, for example). It is just a matter
of what you want the system to do. That way, you can have the system the way
you want it to work, rather than bieng limited to the way we thought you' d want
it to work. (After all, a no-compromise, high performance audio system should
not be "one size fits all.")
Conventional audio DSP design requires the addition of costly hardware every

audio computer

time you wish to add functionality . In these designs, Dolby Digital (AC-3) has its
own, dedicated DSP chip and associated supporting circuitry; so does DTS; so
does MPEG/Musicam. Want a new feature? Buy more hardware.
This strikes us as ridiculous.
Y ou would not buy a computer for writing, knowing that you would have to buy
another computer for calculations, and another for graphics, and a fourth for data-
base work. To do so would be enormously wasteful, as expensive microproces-
sors would sit idly by while you were doing something else.
The same is true in "audio computers."
The Proceed Audio Video Preamplifier is helping to define a new generation of
powerful DSP (Digital Signal Processing) engines that can load software in and
out of memory dynamically, as your computer does. Want to listen to a Dolby
Digital soundtrack? The AVP loads the appropriate software and runs it. Movie
over, want to listen to CD? No problem. Oh, the CD is DTS-encoded? Still no
problem — the DTS software is loaded and runs on the same chip that had been
running Dolby Digital a few moments ago.
Madrigal was an early partner of Motorola in developing the next generation of
DSP chips, the 56300-series. Designed to replace the aging 5600X series, these
new chips offer twice the performance and vastly more flexibility . With two such
chips in each Audio Video Preamplifier, we have the power to run these pro-
grams as well as our own proprietary digital filtering algorithms.
Why did we develop such advanced technology? Simple: better performance for
today, and for tomorrow.
