The MOON P-8 preamplifier is a dual-mono fully balanced differential design, representing
the next generation of MOON high-performance audio components. Using several newly developed proprietary technologies, this preamplifier yields
absolutely no sonic colorations, a level of transparency second-to-none, and possesses a signal-to-noise ratio would have been considered
unattainable until now. Further raising the bar, the P-8 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:
· 2-chassis design with the larger chassis housing the power supply, digital controller circuitry and
software processing. The smaller chassis contains audio circuitry ONLY
· RS-232 port for (i) full unsolicited bidirectional feedback and (ii) firmware updates
· Custom proprietary toroidal transformer design 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
· A dual-mono oversized power supply features 6 stages of DC voltage regulation and extensive
choke filtering
· SimLink controller port for 2-way communications with other compatible MOON components
· M-Ray volume control based on the R-2R resistor array configuration using metal film surface
mount resistors with 0.1% tolerances, resulting in no sonic degradation of the audio signal,
regardless of the selected volume setting
· M-Lock for “user selectable” maximum volume setting lock-out for each line input
· Power supply voltage regulation includes i²DCf (Independant 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 - 40 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 P-8 is bypassed
· 530 individual volume steps in 1dB and 0.1dB increments
· 12 Volt trigger outputs for remote operation
· An exceptionally short signal path measuring less than 8 inches in length from the rear panel's input to output connectors, yielding a much faster transient response
· Fully differential, no global feedback circuit topology, using absolutely no capacitors anywhere in the audio signal path
· 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
· 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-2 remote control.

Overseas MOON P-8 RS
The RS series of MOON audio components benefit from an even higher standard
of manufacturing process than the regular MOON versions. All significant differences are contained within the circuitry and construction
of each model.
RS versions are built using different materials and parts in certain areas. For example, printed
circuit boards are of a higher temperature grade than that of the military specification FR-4 material we normally use; Their traces are gold-plated
instead of a tin/lead composite. As well, all capacitors use improved dielectric materials.
MOON RS models meet and/or exceed stricter manufacturing processes as required to pass many international
safety standards such as those imposed by the E-U, Japan and South Korea. Cosmetically, the ONLY difference is the RS
logo on the front panel.
