Its production was discontinued a few years ago, but the requests to bring it back were overwhelming. That’s why we’ve introduced its return, with a new and improved design. The aesthetics of the Phono One is unchanged, however, maintaining the classic and timeless look of the original version. The Phono One, from its beginning, was designed for those who require a phono preamplifier that offers the highest possible sound quality.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eTechnical Specifications\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eType: Stereo Phono Valve preamplifier\u003c\/li\u003e\n\u003cli\u003eClass: pure A\u003c\/li\u003e\n\u003cli\u003eRIAA : passive +\/- 0.1 dB (20 Hz \/ 20 KHz)\u003c\/li\u003e\n\u003cli\u003eOutput Impedance: 800 ohm.\u003c\/li\u003e\n\u003cli\u003eOutputs: 1 x line\u003c\/li\u003e\n\u003cli\u003eGain : 54 dB\u003c\/li\u003e\n\u003cli\u003eTotal Harmonic Distortion (THD): 0.1 % @ 1V output\u003c\/li\u003e\n\u003cli\u003eSignal to Noise Ratio (S\/N): 80 dB\u003c\/li\u003e\n\u003cli\u003eInputs: 1 for MM or High Output MC cartridge (\u0026gt;2mV)\u003c\/li\u003e\n\u003cli\u003eInput Impedance: 47 Kohm – 100 – 50 – 22 ohm \/ 100 – 200 – 320 – 420 pF ( selectable)\u003c\/li\u003e\n\u003cli\u003eFeedback factor: 0 dB.\u003c\/li\u003e\n\u003cli\u003eValves: 5 x ECC83 \/ 12AX7\u003c\/li\u003e\n\u003cli\u003ePower supply: external\u003c\/li\u003e\n\u003cli\u003eDimension: 37.3 x 5.84 x h 24.63 cm.\u003c\/li\u003e\n\u003cli\u003eNet Weight: 3.6 Kg circa (including power supply)\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Unison Research","offers":[{"title":"Default Title","offer_id":59018979901775,"sku":"UNS.PHONOONE.MH","price":3100.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0796\/1663\/9311\/files\/unison-research-phono-one-mahagon-image1-big_ies14112944.jpg?v=1791287580","url":"https:\/\/music1st.eu\/products\/uns-phonoone-mh","provider":"MUSIC1ST","version":"1.0","type":"link"}
