Updated: December 19, 2006
P-8 Reference Dual-mono Preamplifier
|
 
|
Also available with black faceplate      
|
|  
|
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 MOON 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, software
processing and the LED display. The smaller chassis contains ONLY audio circuitry ·
Full unsolicited RS-232 bidirectional feedback ·
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 ·
An oversized dual-mono power supply features 6 stages of DC voltage regulation and choke filtering ·
SimLink controller port allows for 2-way communications between other compatible MOON Evolution Series components ·
M-Ray volume control circuit based on the R-2R resistor array configuration that uses 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 circuit 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 volume of the P-8 is bypassed ·
530 individual volume steps in 1dB and 0.1dB increments ·
Fully differential, no global feedback circuit topology, using absolutely no capacitors anywhere in the audio signal path ·
An exceptionally short signal path measuring less than 9 inches in length from the rear panel's input to output
connectors, yielding a much faster transient response ·
Four-layer PCB tracings; 1 on top for ground plane, 1 on the bottom for power circuitry and 2 in middle for the
audio signals. The advantages include better ground and power supply circuit layouts resulting in a much shorter
signal path and dramatically improved signal-to-noise ratio ·
Extremely 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 ·
Low operating temperature for a longer than normal life expectancy.

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.
