The Moon 820S is a reference outboard power supply which can upgrade the performance of the 740P, 610LP, 810LP, 650D, 750D or 780D.

• Two custom proprietary toroidal transformers with lower magnetic, electrical and thermal loss, for an improved power transfer and a lower regulation factor. The result is increased current speed and better dynamics; one each for analog and digital power supplies.

• The analog and digital power supplies each have 2 special “pi-type” filters after the inital voltage rectification stage that reduce AC transmission noise, using 40,000uF of capacitance (4 x 10,000 uF) and dual choke inductance (2x 20mH).

• The analog and digital supplies each have 4 stages of our proprietary M-R2S circuit; A fully discrete voltage regulation circuit using a “precision reference” feeding an amplifier made up of numerous IC’s and transistors as opposed to a single voltage regulation chip. M-R2S outputs pure DC power that is exceptionally fast, very precise, has a virtually unmeasureable noise level, as well as absolute stable voltage.

• 4-Layer printed circuit boards with pure copper tracings and extremely low impedance characteristics yielding much shorter signal paths and drastically reduced noise levels.
