MC only with no superfluous features, and easy front-panel controls for cartridge settings\u003c\/h2\u003e\n\u003cp\u003eThe reference Aura MC stage is the culmination of decades of electronic design development. It is a fully adjustable, three-stage, all symmetrical pre-amplifier designed purely to extract the very best performance from your moving coil cartridge and vinyl playback system.\u003cbr\u003e\u003c\/p\u003e\n\u003cp\u003eBuilt into a completely re-designed custom case, the Aura is dedicated to moving coil cartridges and stays clear of any compromises. There are no superfluous functions as they obstruct the signal path and degrade the sound quality. \u003cbr\u003e\u003c\/p\u003e\n\u003ch3\u003eDesign Innovation\u003c\/h3\u003e\n\u003cp\u003eThe Rega Aura is a three stage, all symmetrical pre-amplifier. The first stage is a symmetrical, complementary class-A amplifier, using parallel connected Linear Systems ultra-low noise FET (Field Effect Transistor) transistors configured as a symmetrical compound pair input stage. The use of FET transistors ensures there is no bias current flowing in the cartridge coil so as not to upset the delicate magnetic geometry of the cartridge. The input circuit configuration also alleviates the use of any coupling components between the cartridge output and the input stage FET transistors, which would degrade the sound. The complementary ultra-low noise FET transistors are carefully graded and matched for optimum performance. This stage drives the passive high-frequency part of the RIAA equalization stage.\u003cbr\u003e\u003cbr\u003eThe second stage is a symmetrical, class A, differential amplifier with a common base driver stage; this is also used as the active amplifier in the low-frequency part of the RIAA equalization stage. The third stage inverts the signal to provide a balanced output along with the output of the second stage; the third stage uses the same circuit topology as used in the second stage. The power supply is a symmetrical, discrete tracking power supply using fast diodes and a low noise voltage reference. Each stage has its own localized power supply and LED referenced current generators. To maximize headroom, the Aura has a power supply voltage, which is 60% higher than normally found in such a pre-amplifier. Very high quality, polypropylene capacitors have been used in the signal path. 1% tolerance polypropylene capacitors are used in the RIAA EQ stages and audio grade capacitors are used in the rest of the circuit. Gain, mute, and mono switching is implemented using high-quality relays.\u003cbr\u003e\u003c\/p\u003e\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eInput sensitivity (200 mV on unbalanced output)\u003c\/strong\u003e \u003cbr data-mce-fragment=\"1\"\u003e67 μV - 69.5 dB Gain Setting I\u003cbr data-mce-fragment=\"1\"\u003e131 μV - 63.5 dB Gain Setting II\u003cbr data-mce-fragment=\"1\"\u003e\u003cbr data-mce-fragment=\"1\"\u003e\u003cstrong\u003eGain input to unbalanced output\u003c\/strong\u003e\u003cbr data-mce-fragment=\"1\"\u003e63.5 dB min\u003cbr data-mce-fragment=\"1\"\u003e69.5 dB max\u003cbr data-mce-fragment=\"1\"\u003e\u003cbr data-mce-fragment=\"1\"\u003e\u003cstrong\u003eInput load:\u003c\/strong\u003e 50, 100, 150, 300, 400 Ω\u003cbr data-mce-fragment=\"1\"\u003e\u003cbr data-mce-fragment=\"1\"\u003e\u003cstrong\u003eCapacitive load:\u003c\/strong\u003e 1000, 2000, 3200, 4300, 5700 pF\u003cbr data-mce-fragment=\"1\"\u003e\u003cbr data-mce-fragment=\"1\"\u003e\u003cstrong\u003eOutput resistance (balanced, unbalanced):\u003c\/strong\u003e 100, 200 Ω\u003cbr data-mce-fragment=\"1\"\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cmeta content=\"text\/html; charset=utf-8\" http-equiv=\"content-type\"\u003e\u003cstrong\u003eDimensions (HWD):\u003c\/strong\u003e 17.1\" x 13.78\" x 3.46\" (435 x 350 x 88 mm)\u003cbr data-mce-fragment=\"1\"\u003e\u003cbr data-mce-fragment=\"1\"\u003e\u003cstrong\u003eWeight:\u003c\/strong\u003e 28.66 lb (13 kg)\u003cbr data-mce-fragment=\"1\"\u003e\u003cbr data-mce-fragment=\"1\"\u003e\u003cbr\u003e\u003c\/p\u003e","brand":"Rega","offers":[{"title":"Default Title","offer_id":32492334284860,"sku":"AURA MC","price":6695.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1564\/1247\/products\/Aurafrontviewwithdropshadow_2048x2048_dfe4a1e7-4bd2-4ff3-abd7-4645f956334c.jpg?v=1741631226","url":"https:\/\/upscaleaudio.pro\/products\/rega-aura-moving-coil-phonostage","provider":"Upscale Audio","version":"1.0","type":"link"}
