MOON 820S Reference Outboard Power Supply

Featuring state-of-the-art, custom-built dual toroidal transformers, choke filtering, and MOON's own MOON Reference Regulation System (M-R2S) circuit, the 820S is capable of doing what was once thought of as virtually impossible: improving on the already superlative power supplies built into MOON's products, by further reducing the noise floor while maintaining an even greater voltage stability. The astonishing sheer "blackness" of the musical background created by the addition of this power supply must be heard to be believed. 

The 820S is equipped with two sets of outputs; It can upgrade the performance of any one, or any combination of two of the following MOON Evolution products simultaneously:

• 740P Preamplifier
• 650D DAC/CD Transports
• 750D DAC/CD Transports
• 610LP Phono Preamplifiers
• 810LP Phono Preamplifiers

Each output provides DC power for both analog circuitry (audio) and digital circuitry (controller, CD transport, front panel displays) on 2 separate and unique XLR type cables.

Features:

Two custom proprietary toroidal transformers 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; One each for analog and digital power supplies

Special "pi-type" filters - 2 for each analog & digital supply - after the inital voltage rectification stage that reduce AC transmission noise, using 40,000uF of capacitance and Dual choke inductance (2x 20mH)

The analogue and digital supplies each have 4 stages of our M-R2S circuit; A fully discrete voltage regulation circuit using a "precision reference" feeding an amplifier comprised 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

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  

Designed to be powered up at all times for optimal performance.
