MOON P-3 Stereo Preamplifier

Congratulations!

Thank you for selecting the MOON P-3 Stereo preamplifier as a part of your hi-fi reproduction
system. This preamplifier 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-chan nel preampli fiers availabl e. We
have been building high performance audio equipment for over 20 years, and the know-how gaine d
through our cumulative experience is an important reason why MOON preamplifiers are s o musically
satisfying.

The performance of your P-3 will continue to improve during the first six weeks of us e. This is the
result of a “break-in” period required for the numerous high quality electronic parts used throughout
this preamplifier.

Please read this manual thoroughly to acquaint yourself with this product’s features prior to using it.
We hope you enjoy listening to the MOON P-3 Stereo preamplifier 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 reproducing these elusive qualities.

MOON P-3 Stereo Preamplifier

Introduction

Your MOON P-3 Stereo preamplifier incorporates many significant design features to achieve its
“world class” level of performance. This is an abbreviated list of the more important features:

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.

An oversized power supply.

An exceptionally short capacitor-free signal path measuring only eleven inches in length for a faster
transient response.

Class “A” circuit topology.

A gain section that uses a Crystal microprocessor functioning as a “shunt to ground” that doesn't
degrade sonic performance regardless of the selected setting.

J-FET input devices and MOSFET output devices.

One single-ended audio input which functions as a “pass-through”, bypassing the gain stage to
accommodate a component such as a home-theater processor, whose own volume control is used instead.

Extremely rigid chassis construction to minimize the effects of external vibrations.

Accurate matching of the very finest high quality electronic components.

A symmetrical circuit design.

Pure copper circuit board tracings with extremely low impedance characteristics.

Designed to be powered up at all times for optimal performance.

Low operating temperature for a longer than normal life expectancy.
