FET-1500C

shly, the first professional

audio manufacturer to release

a MOS-FET power amplifier,

is proud to introduce the next

generation, the FET-I500

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-1500 series is offered in two

variations:

The FET-1500M 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-1500G 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-1500C is supplied without

meters and utilizes barrier strip and 1/4"

inputs. This amplifier provides all of the

same performance benefits as the

FET-1500M at a lower cost.

The FET-1500 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.
