It is a distillation of the core architecture of the flagship MasterPhono, resulting in a streamlined, single-input, all-analog phonostage.\u003c\/p\u003e\n\u003cp\u003eThe mission is all MoFi: to preserve the sonic integrity MoFi’s mastering engineers capture in the studio by extracting maximum information from your cartridge with as little loss as possible—delivering a natural, unforced presentation without unnecessary complexity.\u003c\/p\u003e\n\u003cp\u003eSetup is fast and repeatable with gain and loading controls right on the front panel. Choose the setting that fits your cartridge, then use practical listening tools—mono, subsonic, mute, and dim—to tailor playback for real records in real rooms, without breaking the flow of a listening session.\u003c\/p\u003e\n\u003cp\u003eThe UltraPhono Pro is built around a fully discrete J-FET and MOSFET gain stage and a passive, zero-feedback RIAA network—choices made to preserve natural transients and tonal realism without editorializing the source. A seven-stage regulated power supply provides an exceptionally quiet foundation, letting dynamics and low-level detail come through with ease.\u003c\/p\u003e\n\u003cp\u003eA passive RIAA equalization network with zero feedback preserves natural transients and tonal realism. Precision film-foil parts maintain equalization accuracy within ±0.05 dB.\u003c\/p\u003e\n\u003cp\u003eGain and loading are right on the front panel for fast, repeatable setup. Dial in a cartridge in seconds, then lock it in with confidence.\u003c\/p\u003e\n\u003ch3\u003eFeatures\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eSingle-input implementation of MasterPhono’s core architecture\u003c\/li\u003e\n\u003cli\u003eFully discrete J-FET \u0026amp; MOSFET input\/output stages\u003c\/li\u003e\n\u003cli\u003ePassive RIAA equalization with zero feedback\u003c\/li\u003e\n\u003cli\u003eSeven-stage regulated balanced power supply\u003c\/li\u003e\n\u003cli\u003eFront-panel gain and loading controls\u003c\/li\u003e\n\u003cli\u003eUltra-low-noise design with carefully selected components\u003c\/li\u003e\n\u003cli\u003ePrecision RIAA accuracy (±0.05 dB)\u003c\/li\u003e\n\u003cli\u003eBrushed-aluminum panels with rigid steel frame\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\n\u003cp\u003e\u003cb\u003eInput:\u003c\/b\u003e RCA jack, voltage mode, single-ended\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eGain:\u003c\/b\u003e RCA output: 40 dB, 52 dB, 65 dB; Balanced output: 46 dB, 58 dB, 71 dB\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eLoading:\u003c\/b\u003e 100 ohms, 300 ohms, 500 ohms, 1k ohms, 47k ohms\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eOutput Impedance:\u003c\/b\u003e Balanced: 230 ohms; Unbalanced: 115 ohms\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eMax Output:\u003c\/b\u003e Maximum output @ 1% THD, 10 V RMS\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eRIAA Accuracy:\u003c\/b\u003e ±0.05 dB\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eDimensions (WHD):\u003c\/b\u003e 17\" x 2.5\" x 11.35\"\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eWeight:\u003c\/b\u003e 7 lb.\u003c\/p\u003e","brand":"MoFi Electronics","offers":[{"title":"Default Title","offer_id":52496699883704,"sku":"ULTPHONO-PRO","price":2495.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1564\/1247\/files\/MoFi_UltraPhono_Pro_Angle_Left.jpg?v=1772669445","url":"https:\/\/upscaleaudio.com\/products\/mofi-electronics-ultraphono-pro-mm-mc-phono-stage","provider":"Upscale Audio","version":"1.0","type":"link"}
