The conventional A/V receiver or its modestly powered multi-channel ampliļ¬er counter -
part may be ļ¬ne 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 ADCOMs 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 conļ¬guration 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 typ ical receiver p ower rating schemes), the 7700s
easily deliver all the current and vise-grip driver control that
todays power-hungry, low-impedance loudspeakers demand.
But not only do state of the art home theater ampliļ¬ers 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 . C onventional ampliļ¬er designs are simply incapable of
reproducing such extremes, leaving behind that sonic information
you have paid extra for. To design an ampliļ¬er this fast and accu -
rate required a new design approach: F.A.T. Amps!
The heart of ADCOMs F.A.T. (Fast Analog Transform) technology is
our Power-Rig Ā® 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. a m p s a r e n o t o n l y p o w e r f u l a n d q u i c k b u t a l s o S . A . F. E .Ā®:
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 indeļ¬nitely until the short is corrected!
