F.A.T.AMPS
bringing the legendary power of adcom to
the new frontier of high resolution audio
fast analog transform amplifiers

high resolution
audio raises the bar!
Now, audio playback can be better than
ever before! DVD-Audio and SACD
high-resolution formats provide an
unprecedented level of precision to
audio playback. Thesenew formats have
up to five times the frequency bandwidth
of conventional CDs. The dynamic range
is an incredible 144dB, which is 48dB
more than conventional CD. And both
formats support multi-channel play-
back so you can enjoy the amazing
immersion that a multi-channel audio
system can provide.
can your old audio
system deliver the
promised land of
high resolution?
In the old low-resolution days, amplifier
design was easier. Creating an amp was a
straightforward design process using
tried and true techniques that had not
changed much in many years. But if you
are going to design a power amplifier
that can produce very high output
levels and also amplify signals over a
very wide frequency range, you have to
move fast. To design an amplifier
circuit to be fast and accurate, we
needed to use a new design approach.
f.a.t. amps
to the rescue!
The heart of F.A.T. technology is our
Power-Rig circuit topology which pro-
vides incredible transient response.
When combined with our huge
monoblock power supplies, the massive
power reserves provided by the banks of
power supply capacitance give you Fast
Analog Transform (F.A.T.) technology.
What you get is wide dynamic range and
broad frequency response.
The Result? Cutting-edge power
amplifiers designed to maximize
the performance of the newest high
resolution audio formats. Listen for
yourself and experience what a F.A.T.
amp can do for your audio or home
theater system. And remember: power
never becomes obsolete.
Let’s face it. In the world of audio, loudspeakers are a necessary evil. Until some mad scientist develops the direct neural tap, we will always need to
listen to music as sound waves that travel through the air. But why are loudspeakers evil? Because speakers are power-hungry beasts that waste
tons of energy, especially the smaller, less efficient mini-monitors so popular today. But fear not. ADCOM power amplifiers can slay the evil
loudspeaker beast. ADCOM power amplifiers have always been designed with a large capacity of output transistors mounted to efficient heat sinks. We have
always designed huge torriodial power transformers with thousands of micro-Farads of power supply capacitance to make sure your power amp has the
reserves and wide dynamic range your evil power-sucking speakers crave.
