The MOON P-7 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, an incredible level of transparency, and a very impressive signal-to-noise ratio. Further raising the bar, the
P-7 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 3 toroidal transformers in conjnction with 5 stages
of DC voltage regulation and extensive choke filtering
· SimLink controller port for 2-way communications with other compatible MOON components
· M-eVOL volume control circuit based on a resistive array configuration with 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
· “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
· 130 individual volume steps in 1dB and 0.5dB increments
· 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 - 24 stages in all
· 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
· 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-7 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.
