Launched in 2006, Discontinued in 2013

The P-7  preamplifier yields no sonic colorations, an incredible level of transparency, and an excellent signal-to-noise ratio. The P-7 can be fully integrated into a custom-install environment via an RS-232 port.

User manual

Technical aspects

 A dual-mono oversized power supply using 2 toroidal transformers in conjunction with 5 stages of DC voltage regulation and extensive choke filtering
 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
 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
 130 individual volume steps in 1dB and 0.5dB increments
 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
 RS-232 port for (i) full unsolicited bidirectional feedback and (ii) firmware updates
 IR input for external control
 12 Volt trigger output for remote operation
 SimLink™ controller port for 2-way communications with other compatible MOON components
 4-Layer printed circuit boards 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
 Includes FRM-2 remote control.
