Introduction
Thank you for selecting the MOON 760A Dual-
Mono power amplifier as a part of your hi-fi
reproduction system. This power amplifier has been
designed to offer state-of-the-art high-end
performance in an elegant package, while retaining
all the sonic hallmarks on which Simaudio has made
its reputation. We have spared no effort to ensure
that it is among the finest two-channel amplifiers
available. We have been building high-performance
audio equipment for over 30 years, and the
know-how gained through our cumulative
experience is an important reason why MOON
amplifiers are so musically satisfying.
Your new amplifier is a true Dual-mono design,
whereby each channel operates completely
independent of the other. The performance of
your 760A will continue to improve during the first
300 hours of listening. This is the result of a “break-
in” period required for the numerous high quality
electronic parts used throughout this amplifier.
Before setting up your new MOON 760A, we
encourage you to please read this manual
thoroughly to properly acquaint yourself with its
features. We hope you enjoy listening to the
MOON 760A Dual-Mono power amplifier as much
as the pride we have taken in creating this fine
audio product. We understand the power and
emotion of music and build our products with the
goal of faithfully capturing these elusive qualities.

Your MOON 760A Dual-Mono Power Amplifier incorporates many significant design features to achieve its
“world-class” level of performance. This is an abbreviated list of the more important features:
Our “no overall feedback” amplifier circuit design.
The results are: Real-time amplification is achieved
since interactions from the speaker back to the
amplifier are virtually eliminated; More accurate
musical reproduction with respect to tonality; Virtually
non-existent transient intermodulation distortion (which
is far more degrading to sonic performance than
harmonic distortion); The elimination of common
phase errors resulting from feedback.
A custom proprietary toroidal transformer design
with lower magnetic, electrical and thermal loss,
yielding an improved power transfer and lower
regulation factor, resulting in increased current speed
and better dynamics.
Fully balanced differential circuitry up to the output
stage.
Class A output to 5 watts for greater efficiency.
Full unsolicited RS-232 bidirectional feedback.
An oversized power supply.
An exceptionally short signal path for a faster
transient response.
Precision matched and fully decoupled proprietary
MOON Bipolar Output transistors with unprecedented
gain linearity resulting in improved bass response and
even more accurate sonic reproduction.
A high damping factor which yields superior musical
dynamics, improved signal speed and refined timbre
accuracy.
Ultra rigid chassis construction to minimize the effects
of external vibrations.
Designed to be powered up at all times for optimal
performance.
