Simaudio Moon 850P


Significant Design Features:
· 2-chassis design with one chassis housing the power supply, digital controller circuitry and software processing. The other chassis contains the audio circuitry
· The preamplifier's audio section is located on its own dedicated circuit board, which is mounted with our M-Octave damping system· Custom proprietary toroidal transformer design with lower magnetic, electrical and thermal loss, yielding an improved power transfer and lower regulation factor. The result is increased current speed and better dynamics
· A dual-mono oversized power supply features 4 stages of DC voltage regulation and extensive choke filtering
· M-Ray volume control based on the R-2R resistor array configuration using metal film surface mount resistors with 0.1% tolerances, resulting in 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· 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 - 40 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 gain section of the P-8 is bypassed
· 530 individual volume steps in 1dB and 0.1dB increments
· RS-232 port for (i) full unsolicited bidirectional feedback and (ii) firmware updates
· 12 Volt trigger outputs for remote operation
· IR input for external control
· SimLink controller port allows for 2-way communications between other compatible MOON Evolution Series components
· 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
· Fully differential, no global feedback circuit topology, using absolutely no capacitors anywhere in the audio signal path
· Four-layer PCB tracings for 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.
