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.
