A
shly, the first professional
audio manufacturer to release
a MOS-FET power amplifier,
is proud to introduce the next
generation, the FET-1000
Series.
During its first
decade, our original FET
Series became a standard for
applications requiring the utmost in sonic
excellence and extreme reliability. We
now improve upon that reputation by
offering more models with better specifi­
cations than ever before.
The FET-1000 series is offered in two
variations:
The FET-1 OOOM features LED meters
and balanced XLR or 1/4" inputs. This
design is intended for demanding sound
reinforcement, broadcast facilities, re­
cording studios, or any application where
visual monitoring and interfacing with bal­
anced equipment is essential.
The FET-1 OOOC is designed to meet the
needs of professional industrial installa­
tions such as theater, public address and
stadium use. In these situations meters
and XLR inputs are not typically required,
so the FET-1 OOOC is supplied without
meters and utilizes barrier strip and 1/4"
inputs. This amplifier provides all of the
same performance benefits as the
FET-1 OOOM at a lower cost.
The FET-1000 series represents Ashly's
ongoing dedication to extending the
boundaries of technology. Simple, stable
circuitry produces better sound. Ashly
MOS-FET amplifiers use a complemen­
tary, all-discrete design. The driver is pure
class-A and, because it has only two
stages, requires little compensation allow­
ing both speed and linearity with no
crossover-notch distortion.
The output stage consists of paralleled
power MOS-FETs for current gain. The
MOS-FETs have smooth transconduc­
tance curves and run at a relatively high
idle current, again preventing crossover
notch distortion. They require no dissipa­
tion-limiting protective circuitry and pro­
vide virtually infinite power gain, keeping
load reflections from the driver stage.
This promotes stability and low distortion
when driving reactive loads like loud­
speakers.
Special attention is paid to overload
performance; when an Ashly amp is over­
driven, it will clip cleanly with a slightly
rounded edge totally free from spikes and
glitches. Total immunity to power supply
variations insures that transient distor­
tions are never generated on program
material with wide dynamic range.
The result: powerful and quick ampli­
fiers that deliver unrestrained, uncolored
sound quality with remarkable accuracy.
Each Ashly power amplifier, like all Ashly
products, is now fully covered by our
exclusive five-year worry-free warranty.
