The incredible success of Pro-Ject's Phono Box Ultra 500, incited it to introduce this marvelously sounding phono preamp into the regular S2 line. The solid metal casing protects against interference, and the internal design remains as spectacular as before.\u003cbr\u003e\u003cbr\u003eA fully discrete, op-amp-less design, allows an incredibly harmonious sound. On top of leaving out operational amplifiers,  Pro-Ject decided to use polystyrene capacitors, which significantly contribute to the high-end sound of the Phono Box S2 Ultra. These capacitors are known amongst audiophiles as the holy grail for phono preamplifiers. The split RIAA equalization enables a pin-point accurate representation of the RIAA curve, a luxury many other phono preamps do not possess.\u003cbr\u003e\u003c\/p\u003e\n\u003ch3\u003eFeatures\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eNo operational amplifiers used\u003c\/li\u003e\n\u003cli\u003eAudiophile-grade polystyrene capacitors\u003c\/li\u003e\n\u003cli\u003ePrecise split RIAA equalization\u003c\/li\u003e\n\u003cli\u003eSwitchable subsonic filter\u003c\/li\u003e\n\u003cli\u003eSwitchable input impedance\/capacitance\u003c\/li\u003e\n\u003cli\u003eFour adjustable gain levels\u003c\/li\u003e\n\u003cli\u003eSolid metal casing protects from interference\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eInput impedance:\u003c\/strong\u003e 10\/100\/1,000 \/47,000 Ohm\u003cbr\u003e\u003cstrong\u003eInput capacitance:\u003c\/strong\u003e 100\/220 pF\u003cbr\u003e\u003cstrong\u003eGain switch:\u003c\/strong\u003e 40\/43\/60\/63 dB\u003cbr\u003e\u003cstrong\u003eSubsonic switch:\u003c\/strong\u003e -18 dB @ 20 Hz\u003cbr\u003e\u003cstrong\u003eSignal-to-noise ratio:\u003c\/strong\u003e 89 dB\u003cbr\u003e\u003cstrong\u003eTHD+N (MM\/MC):\u003c\/strong\u003e 0.00052% \u003cbr\u003e\u003cstrong\u003eRIAA accuracy:\u003c\/strong\u003e \u0026lt; 0.4 dB \/ 20 Hz - 20 kHz\u003cbr\u003e\u003cstrong\u003ePower consumption:\u003c\/strong\u003e 18 V \/ 80 mA\u003cbr\u003e\u003cstrong\u003eOutboard power supply:\u003c\/strong\u003e 18 V DC \/ 500 mA\u003cbr\u003e\u003cstrong\u003eDimensions (WHD): \u003c\/strong\u003e4\" x 1.45\" x 4.68\" (103 x 37 x 119 mm)\u003cbr\u003e\u003cstrong\u003eWeight:\u003c\/strong\u003e 1.25 lb (570 g)\u003cbr\u003e\u003c\/p\u003e","brand":"Pro-Ject","offers":[{"title":"Black","offer_id":31369106030652,"sku":"PHONOBOX S2 ULTRA BLK","price":319.0,"currency_code":"USD","in_stock":true},{"title":"Silver","offer_id":31369106063420,"sku":"PHONOBOX S2 ULTRA SIL","price":319.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1564\/1247\/products\/phono-box-s2-ultra-1-product.jpg?v=1741631546","url":"https:\/\/upscaleaudio.pro\/products\/pro-ject-phono-box-s2-ultra-phonostage","provider":"Upscale Audio","version":"1.0","type":"link"}
