On top of omitting Op-Amps, the selected polystyrene capacitors (known among audiophiles as the ‘holy grail’ for phono preamplifiers) significantly contribute to the clean, clear, detail-oriented sonics that S2 Ultra delivers. With wide-ranging flexibility in gain, load \u0026amp; capacitance, it can handle with grace almost any cartridge you throw at it. Split RIAA equalization creates an ultra-accurate representation of the RIAA curve, further refining what you hear. To protect the circuitry from potentially harmful interference, the S2 enclosure features a 2-layer enclosure comprised of aluminum \u0026amp; steel.\u003c\/p\u003e\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eGeneral\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 1.25 lbs\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDimensions:\u003c\/strong\u003e 4.7\" x 4.1\" x 1.4\"\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/pro-jectusa.com\/international-warranty\/\" title=\"Pro-Ject Official International Warranty Page\" target=\"_blank\"\u003ePro-Ject 2 Year Warranty\u003c\/a\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003ePhonostage\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInput Impedance:\u003c\/strong\u003e 10Ω, 100Ω, 1kΩ, 47kΩ \/ 100pF\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInput C\u003c\/strong\u003e\u003cstrong\u003eapacitance\/impedance:\u003c\/strong\u003e 100pF, 200pF, 320pF and 420pF *\/47kΩ B (Input capacitance is irrelevant for low output MC cartridges.)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInput gain:\u003c\/strong\u003e 40 and 43dB B \/ 60 and 63dB A\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSNR MM:\u003c\/strong\u003e 85dBV (90dBV – ‘A’ weighted)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSNR MC:\u003c\/strong\u003e 65dBV (71dBV – ‘A’ weighted)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTHD MM:\u003c\/strong\u003e \u0026lt;0,0005%\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTHD MC:\u003c\/strong\u003e \u0026lt; 0,004%\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRIAA-equalisation curve accuracy:\u003c\/strong\u003e \u0026lt;0,4dB \/ 20Hz – 20kHz\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSubsonic filter:\u003c\/strong\u003e at 20Hz with 18dB\/octave\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInput:\u003c\/strong\u003e 1 pair RCA\/phono sockets\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLine-level output:\u003c\/strong\u003e 1 pair RCA\/phono sockets\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOutboard power supply:\u003c\/strong\u003e 18V\/500mA DC, suitable for your country’s mains supply\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePower consumption:\u003c\/strong\u003e 18V\/80mA DC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eA:\u003c\/strong\u003e typical for low output MC cartridges\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eB:\u003c\/strong\u003e typical for MM cartridges or high output MC\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Pro-Ject","offers":[{"title":"Black","offer_id":41236686209099,"sku":"PJ-PHONOBOX-S2-ULTRA-BLK","price":319.0,"currency_code":"USD","in_stock":false},{"title":"Silver","offer_id":41861284167755,"sku":"PJ-PHONOBOX-S2-ULTRA-SLV","price":319.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0023\/9255\/5595\/files\/project-phonobox-s2-ultra.webp?v=1736799092","url":"https:\/\/bloomaudio.mom\/products\/pro-ject-phono-box-s2-ultra","provider":"Bloom Audio","version":"1.0","type":"link"}
