Simaudio 820S Power Supply

Beautiful Customer Trade In. As New Box Packing and Manual. Reference Outboard Power Supply which can upgrade the performance of the 740P, 610LP, 810LP , 650D , 750D or 780D Design features 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. The following accessories should be included inside the box with your power supply: 9 AC power cable Two (2) 4-Pin XLR cables for analog section DC power Two (2) 5-Pin XLR cables for digital section DC power Owner’s manual Warranty and product registration information (USA and Canada only)
