fast analog transform amplifiers
The conventional A/V receiver or its modestly powered multi-channel amplifier counter-
part may be fine for dribbling some inoffensive background music around the home. But
to accurately drive and control serious loudspeaker designs of realistic live-sound levels in
large volume spaces... power and grunt of Big Rig proportion is in order!
Introducing ADCOM’s latest entries into the world of earthmoving
equipment: the GFA-7705 and GFA-7707. The same Big Rig design
available in either 5- or 7-channel versions. And should your system
need future expansion the 5-channel 7705 can easily be upgraded
to a 6- or 7-channel configuration by your ADCOM dealer.
At a real 200 watts per channel (continuously into 8 ohms, [300
watts into 4 ohms] at rated bandwidth/distortion—not to be
confused with typical “receiver” power rating schemes), the 7700s
easily deliver all the current and vise-grip driver control that
today’s power-hungry, low-impedance loudspeakers demand.
But not only do state of the art home theater amplifiers need to be
this powerful—they also need to be fast. The new high-resolution
multi-channel audio formats require greater speed and low-distor-
tion precision across a wider frequency bandwidth than ever
before. Conventional amplifier designs are simply incapable of
reproducing such extremes, leaving behind that sonic information
you have paid extra for. To design an amplifier this fast and accu-
rate required a new design approach: F.A.T. Amps!
The heart of ADCOM’s F.A.T. (Fast Analog Transform) technology is
our Power-Rig® direct-coupled circuit topology which both elimi-
nates (slower) capacitive coupling in the signal path and also
prevents any possible speaker-damaging stray DC current from
reaching the output.
When combined with our monstrous power supply banks the result-
ing extremely wide bandwidth (3 Hz-130 kHz), high-current swing
capability and wide dynamic range deliver the necessary rapid
transient response to effectively track and amplify all subtleties and
nuances without loss or strain.
F.A.T. amps are not only powerful and quick but also S.A.F.E.®:
Self-Annealing Fuse-Equipped! In the event of a dead short to either
a loudspeaker or speaker cable leads, the GFA-7705/07 enters into
the self-protect S.A.F.E. mode. The S.A.F.E. circuit continues to pro-
tect your Big Rig investment indefinitely until the short is corrected!
