ot too many years ago the only audio power
amplifiers available to the consumer were two-
channel stereo designs. As a result, early home
theater enthusiasts needed to buy two stereo amplifiers
and one mono amplifier just to power a simple Dolby Pro-
Logic® home theater system. As the
popularity of home theater
grew, many manufacturers
began to offer 5 and 6
channel amplifiers based on
existing lower-power
amplifier designs. These
amplifiers worked fine with
Dolby Pro-Logic decoders
because Pro-Logic
decoders “phase steer” their
signals, and never demand
high power from all channels at
the same time. 
In terms of amplifier performance
however, the new Dolby Digital® and
DTS® formats separate the men from
the boys. These new digital formats offer 5.1 channels of
full-range discrete audio and are not only capable of
demanding power from multiple channels at the same
time, they frequently do. This means that using Dolby
Digital® and DTS® formats requires a power amplifier
capable of high power with ALL channels driven.
Unfortunately, most affordable multi-channel amplifiers fail
in this respect today.
The Outlaw design team, fully aware of the deficiencies of
the current crop of amplifiers, went to one of the industry’s
premier amplifier manufacturers to design the Model 750.
We asked him to create an amplifier that had no limitations
in the reproduction of movie sound tracks, or in any of the
new digital audio formats. Our goal was to produce an
investment-grade component, one that we would be proud
to own ourselves. In addition to meeting our performance
standards, this amplifier had to be affordable, and highly
reliable.
From these design criteria came Outlaw Audio’s first
product, the Model 750 five-channel power amplifier. From
the glass-epoxy, mil-spec circuit boards to the rugged, 13
gauge powder-coated, steel chassis, this unit utilizes the
finest components available. 
The heart of the Model 750 is a high-current power supply
with enough energy to reproduce any dynamic, whether it
comes from a soundtrack explosion or a symphony
crescendo. We accomplished this through the use of a
massive toroidal transformer with ten separate windings,
one pair for each channel of the amplifier. In addition, each
channel has approximately 20,000 uF of total filter
capacitance, provided by computer-grade, premium
electrolytic filter capacitors. This guarantees that the Model
750 has ample reserves of peak power
regardless of signal demands.
To manage the heat produced by all
high-power amplifiers, most
manufacturers rely on
inexpensive muffin fans to
blow air over the output
transistors. We feel this is
unacceptable, because fans
create noise which is clearly
audible in a home theater
system. In addition, fans suck
dirt and dust into the unit
which can shorten the product
life. Rather than use
inexpensive fans, we chose the more elegant
solution of utilizing over-sized heat sinks to dissipate the
heat. Each of the five amplifier modules in the Model 750
is built around a huge milled-aluminum heat sink with 396
sq. in of surface area. This allows the amplifier to stay cool
during operation, while remaining absolutely silent.
