During its first decade, our original FET Series becâme 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 specifications than ever before. The FET-2000 series is offered in two variations: The FET-2000M features LED meters and balanced XLR or 1/4" inputs. This design is intended for demanding sound reinforcement, broadcast facilities, recording studios, or any application where visual monitoring and interfacing with balanced equipment is essential. The FET-2000C is designed to meet the needs of professional industrial installations such as theater, public address and stadium use. In these situations meters and XLR inputs are not typically required, so the FET-2000C is supplied without meters and utilizes barrier strip and 1/4" inputs. This amplifier provides all of the same performance benefits as the FET-2000M at a lower cost. The FET-2000 series represents Ashly’s ongoing dedication to extending the bound- aries of technology. Simple, stable circuitry produces better sound. Ashly MOS-FET amplifiers use a complementary, all-discrete design. The driver is pure class-A and, because it has only two stages, requires little compensation allowing 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 transconductance curves and run at a relatively high idle current, again preventing crossover notch distortion. They require no dissipation-limiting protective circuitry and provide virtually infinite power gain, keeping load reflections from the driver stage. This promotes stability and low distortion when driving reactive loads like loudspeakers. Special attention is paid to overload performance; when an Ashly amp is overdriven, it will clip cleanly with a slightly rounded edge totally free from spikes and glitches. Total immunity to power supply variations insures that transient distortions are never generated on program material with wide dynamic range. The result; powerful and quick amplifiers that deliver unrestrained, uncolored sound quality with remarkable accuracy. To ensure compatibility with every installation and insure the protection of every user, Ashly power amplifiers are listed with U.L. Plus, each is backed by Ashly's exclusive five-year worry-free warranty. U.L.
