Product Description
| · 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 6 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 (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 – 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 850P 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 for 2-way communications with other compatible MOON 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 · 4-Layer PCB’s 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 · Improved reliabilty through the elimination of moving parts · Includes FRM-3 remote control. |
