Introduction
Thank you for selecting the
MOON 820S power supply
as a part of your hi-fi reproduction system. This power
supply has been designed to upgrade the “already
state-of-the-art of performance” of any one, or any
combination of two of the following MOON Evolution
products simultaneously: 740P Preamplifier, 650D and
750D DAC/CD Transports, 780D DAC, 610LP and 810LP
Phono Preamplifiers.
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 products are so musically satisfying.
Before setting up your new MOON 820S , we encourage
you to please read this manual thoroughly to properly
acquaint yourself with its features. We hope you enjoy
using the
MOON 820S power supply 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 820S Power Supply incorporates many
significant design features to achieve its “world-class”
level of performance. This is an abbreviated list of the
more important features:
Two custom proprietary toroidal transformers with lower
magnetic, electrical and thermal loss,
yielding an improved power transfer and lower regulation
factor. The result is increased current speed
and better dynamics; One each for analog and digital power
supplies.
Special "pi-type" filters – 2 for each for analog & digital
supplies - after the inital voltage rectification stage
that reduce AC transmission noise, using 40,000uF of
capacitance and dual choke inductance (2x 20mH).
The analog and digital supplies each have four stages of our
M-R2S circuit; A fully discrete voltage
regulation circuit using a "precision reference" feeding an
amplifier comprised of numerous IC's and transistors, as
opposed to a single voltage regulation chip. M-R2S outputs
pure DC power that is exceptionally fast, very precise, has a
virtually unmeasureable noise level, as well as absolute stable
voltage.
4-Layer printed circuit boards with pure copper tracings and
extremely low impedance characteristics
yielding much shorter signal paths and drastically reduced
noise levels.
Ultra rigid chassis construction to minimize the effects of
external vibrations.
Designed to be powered up at all times for optimal
performance.
