Marsh Sound Design A-200 Stereo Power Amplifier - Manual (Page 7)

Preface

ust as a great performer spends years learning his or her instruments, so a master designer spends years
understanding the complexities of audio circuitry and the science of electronics.
The Marsh Sound Design team builds its products to the most exacting standards of design and construction, for
simplicity of use, long life and timeless performance. Your investment in a Marsh product means that you can
forget about the hardware and focus on years of enjoyment.
For more than 30 years, author, lecturer, engineer, and inventor, has shared the art of
perfecting audio circuits with other designers. Now, his goal is to bring you his accumulated experience in the
service of music.
The A200S gives out 120 watts per channel, for a total of 240 watts. The A200S is designed with a High End circuit
with very low-noise FETs. A balanced, complimentary differential input circuit makes the A200S even more
linear than other systems.
Complex? Yes, but elegant and effective. The output stage has two pairs of high current, paralleled, bi-polar
power transistors to meet the peak current demands of any speaker system. Dynamic transient sounds come
through with full impact and clarity. Servo-controlled, direct-coupled circuitry is used throughout the circuitry
for extremely high resolution sound.
