The Evolution
of preamplification
The MOON 740P preamplifier is a
dual-mono fully balanced
differential design, following in
the footsteps of the MOON 850P
reference. This "next generation"
series preamp uses various
recently in-house developed
technologies that help create a
level of performance that can be
best described as astounding.
Intended for those seeking
high-performance in an elegant,
stylish yet uncomplicated package,
the MOON 740P leaves your music
uncolored and free of any grain and
noise; The purity of the signal
remains uncompromised, allowing the
music to be heard as was intended
from day it was recorded. Further
raising the bar, as is the case with
all series models, the
740P can be fully integrated into a
custom-install environment via an
RS-232 port. As well, a plethora of
user selectable cosmetic options are
available at the time of purchase.
Significant Design Features
Full unsolicited RS-232
bidirectional feedback
A dual-mono oversized power supply
using 2 toroidal transformers in
conjunction with 5 stages
of DC voltage regulation and
extensive choke filtering
4 stages of our newly developed
M-LoVo (MOON Low Voltage) DC
regulation circuit; a highly
sophisticated circuit made up of a
clever combination of IC’s and
discrete parts that is virtually
free of noise, yielding an
exceptionally fast, precise, and
stable DC voltage. The result is a
power supply with a virtually
unmeasureable noise floor
SimLink controller port for 2-way
communications with other compatible
MOON components
M-eVOL2 volume control circuit using
MDAC’s (operating in a current
steering R-2R configuration)
which alter the audio signal’s
amplitude yielding no sonic
degradation of the signal,
regardless
of the selected volume setting
530 individual volume steps in 1dB
and 0.1dB increments
M-Lock for “user selectable” maximum
volume setting lock-out for each
line input
Power supply voltage regulation
includes i²DCf (Independent
Inductive DC Filtering); There is
one inductor dedicated to each
integrated circuit type component (DAC,
Op-Amp, etc.) in the
audio circuit’s signal path - 24
stages in all
“Gain offset” for each individual
line input with a ±10dB range
Each line input is fully
configurable to be “home-theater
ready”, where the gain section of
the
740P is bypassed
4-Layer PCB’s with pure copper
tracings for a much shorter signal
path; This results in
greater sonic accuracy and a
dramatically improved
signal-to-noise ratio
12 Volt trigger output for remote
operation
Ultra rigid chassis construction to
minimize the effects of external
vibrations
Accurate matching of the very finest
quality electronic components in a
symmetrical circuit design
Improved reliabilty through the
elimination of moving parts
Includes FRM-3 all-aluminum back-lit
remote control.
