Technical aspects

4 stages of our M-LoVo (MOON Low Voltage) DC regulation circuit; a highly sophisticated circuit that is virtually free of noise, yielding an exceptionally fast, precise, and stable DC voltage. The result is a power supply with a virtually unmeasureable noise floor
A dual-mono oversized power supply using 2 toroidal transformers in conjunction with 5 stages of DC voltage regulation and extensive choke filtering
M-eVOL2 volume control circuit using MDAC’s (operating in a current steering R-2R configuration) which alter the audio signal’s amplitude, yielding no sonic degradation of the signal, regardless of the selected volume setting
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; 24 stages in all
M-Lock for “user selectable” maximum volume setting lock-out for each line input
“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 740P is bypassed
 RS-232 port for (i) full unsolicited bidirectional feedback and (ii) firmware updates
IR input for external control
12 Volt trigger output for remote operation
SimLink™ controller port for 2-way communications with other compatible MOON components
4-Layer printed circuit boards 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
Includes FRM-3 remote control
