MOON EVOLUTION SERIES                                 Updated: May 19, 2009
P-7 Dual-mono Preamplifier
 



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 MOON 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
· An oversized dual-mono power supply using 3 toroidal transformers in conjnction
  with 5 stages of DC voltage regulation and extensive choke filtering
· SimLink controller port allows for 2-way communications between other compatible
  MOON Evolution Series 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-7 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
· Four-layer PCB tracings; Layers 1 and 3 for the audio signals, layer 2 for the ground
  plane and the bottom layer for power supplies. The advantages include better
  ground and power supply circuit layouts resulting in a much shorter signal path
  and 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
· Low operating temperature for a longer than normal life expectancy.

Overseas MOON RS Series

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.
