2-chassis design with the larger chassis housing the power supply, digital controller circuitry, software processing and the LED display. The smaller chassis contains ONLY audio circuitry · Full unsolicited RS-232 bidirectional feedback · 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 · An oversized dual-mono power supply features 6 stages of DC voltage regulation and choke filtering · SimLink controller port allows for 2-way communications between other compatible MOON Evolution Series components · M-Ray volume control circuit based on the R-2R resistor array configuration that uses 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 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 - 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 volume of the P-8 is bypassed · 530 individual volume steps in 1dB and 0.1dB 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 9 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 reliabilty through the elimination of moving parts · Low operating temperature for a longer than normal life expectancy.
