P-7 RS Pre-Amplifier

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. "Celebrating Over 25 Years Of Excellence".

Significant Design Features:

• Full unsolicited RS-232 bidirectional feedback

• An oversized dual-mono power supply using 3 toroidal transformers in conjunction 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 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 - 24 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-7 is bypassed

• 130 individual volume steps in 1dB and 0.5dB 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 8 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 reliability through the elimination of moving parts

• Low operating temperature for a longer than normal life expectancy.
