{"product_id":"ortofon-hifi-hifi-transformateur-st-7-387879","title":"TRANSFORMATEUR ST-7","description":"\u003ch3\u003eA Dedicated Solution for High-Quality Vinyl Playback\u003c\/h3\u003e\u003cp\u003eThis phono preamp is designed for users who want to get the most from their turntable without adding unnecessary bulk to their setup. Its discreet format and 2 kg weight reflect a serious design, intended to fit easily into an audio cabinet, listening space, or setup focused on digitizing records.\u003c\/p\u003e\u003cp\u003eIn a vinyl chain, the role of the phono preamp is crucial. It determines the output level, tonal balance and clarity of the musical message. Here, the approach clearly focuses on finesse, with wide bandwidth and performance suited to attentive listening, whether with recent pressings or older records.\u003c\/p\u003e\u003ch3\u003eFor Vinyl Enthusiasts, from the Living Room to the Dedicated Setup\u003c\/h3\u003e\u003cp\u003eThis model is particularly well suited to vinyl enthusiasts looking for a reliable link between their turntable and listening system. It can be integrated into a home hi-fi setup, a dedicated listening corner, or a work environment where the quality of analog playback remains essential.\u003c\/p\u003e\u003cp\u003eIt is also aimed at demanding users who want to make better use of their cartridge's potential and gain greater definition in the bass, midrange and high frequencies. For a collector, music lover or user accustomed to comparing different sonic signatures, this type of electronics provides real added value in terms of stability and precision.\u003c\/p\u003e\u003cp\u003eIn a more DJ- or archiving-oriented context, it can also serve as an interesting foundation for capturing a clean signal before recording or broadcasting. Its compact footprint makes it easy to integrate into confined spaces, without sacrificing perceived quality or the system's overall coherence.\u003c\/p\u003e\u003ch3\u003eWide-Band Reproduction for Enhanced Detail\u003c\/h3\u003e\u003cp\u003eThe first major strength of this phono preamp is its \u003cstrong\u003efrequency response from 15 Hz to 45 kHz\u003c\/strong\u003e. This extended range promotes spacious reproduction, with solid bass, clear midrange and highs that retain air without harshness. For vinyl listening, this type of performance is particularly appreciated when the goal is to preserve the nuances of a recording.\u003c\/p\u003e\u003cp\u003eThe \u003cstrong\u003e24 dB gain at 1 kHz\u003c\/strong\u003e effectively boosts the signal from the cartridge while maintaining balanced reproduction. This results in a more comfortable, better-structured listening experience that is easier to integrate into an existing chain. The goal is not to add excessive coloration, but to convey the musical content with clarity and control.\u003c\/p\u003e\u003cp\u003eAnother interesting point is that the stated values highlight a design focused on the system's electrical coherence. The \u003cstrong\u003e47 kOhms output impedance\u003c\/strong\u003e and \u003cstrong\u003e200 pF output capacitance\u003c\/strong\u003e contribute to integrating the preamp into a carefully designed setup. The recommended cartridge impedance, specified from \u003cstrong\u003e2 to 60\u003c\/strong\u003e, also shows that this model was designed to operate within a precise range depending on the selected cartridge.\u003c\/p\u003e\u003cp\u003eFinally, its compact \u003cstrong\u003e122 x 43.5 x 102 mm\u003c\/strong\u003e chassis makes it easy to position near a turntable or amplifier. Weighing \u003cstrong\u003e2 kg\u003c\/strong\u003e, it conveys a reassuring sense of solidity for everyday use, whether for casual listening, building a coherent vinyl system or upgrading an existing setup.\u003c\/p\u003e\n\n\u003ch2\u003eTechnical specifications\u003c\/h2\u003e\n\u003cstyle\u003e@media(max-width:632px){table[data-wb-spec]{display:grid;grid-template-columns:minmax(0,1fr) minmax(0,1fr)}table[data-wb-spec] colgroup{display:none}table[data-wb-spec] tbody,table[data-wb-spec] tr{display:contents}table[data-wb-spec] td{display:block;overflow-wrap:anywhere;grid-row:var(--wb-l);background-color:var(--wb-lb)}table[data-wb-spec] td[data-r]{grid-row:var(--wb-r);background-color:var(--wb-rb)}table[data-wb-spec] td[colspan=\"2\"]{grid-column:1\/-1}table[data-wb-spec] td:empty{display:none}}\u003c\/style\u003e\n\u003ctable data-wb-spec style=\"width:100%;table-layout:fixed\"\u003e\n\u003ccolgroup\u003e\u003ccol style=\"width:25%\"\u003e\u003ccol style=\"width:25%\"\u003e\u003ccol style=\"width:25%\"\u003e\u003ccol style=\"width:25%\"\u003e\u003c\/colgroup\u003e\n  \u003ctr style=\"background-color:var(--wb-neutral-50);--wb-l:1;--wb-r:2;--wb-lb:var(--wb-neutral-50);--wb-rb:transparent\"\u003e\u003ctd style=\"text-align:left\"\u003e\u003cstrong\u003eCategory\u003c\/strong\u003e\u003c\/td\u003e\u003ctd style=\"text-align:left;font-weight:var(--font-body-weight-bolder)\"\u003ePhono Preamps\u003c\/td\u003e\u003ctd data-r colspan=\"2\"\u003e\u003c\/td\u003e\u003c\/tr\u003e\n\u003c\/table\u003e\n\u003ctable data-wb-spec style=\"width:100%;table-layout:fixed\"\u003e\n\u003ccolgroup\u003e\u003ccol style=\"width:25%\"\u003e\u003ccol style=\"width:25%\"\u003e\u003ccol style=\"width:25%\"\u003e\u003ccol style=\"width:25%\"\u003e\u003c\/colgroup\u003e\n  \u003ctr style=\"background-color:transparent;--wb-l:1;--wb-r:5;--wb-lb:transparent;--wb-rb:transparent\"\u003e\u003ctd style=\"text-align:left\"\u003e\u003cstrong\u003eFrequency response\u003c\/strong\u003e\u003c\/td\u003e\u003ctd style=\"text-align:left;font-weight:var(--font-body-weight-bolder)\"\u003e15 Hz - 45 kHz (+0 dB -2.5 dB)\u003c\/td\u003e\u003ctd data-r style=\"text-align:left\"\u003e\u003cstrong\u003eOutput capacitance\u003c\/strong\u003e\u003c\/td\u003e\u003ctd data-r style=\"text-align:left;font-weight:var(--font-body-weight-bolder)\"\u003e200 pF\u003c\/td\u003e\u003c\/tr\u003e\n  \u003ctr style=\"background-color:var(--wb-neutral-50);--wb-l:2;--wb-r:6;--wb-lb:var(--wb-neutral-50);--wb-rb:var(--wb-neutral-50)\"\u003e\u003ctd style=\"text-align:left\"\u003e\u003cstrong\u003eGain\u003c\/strong\u003e\u003c\/td\u003e\u003ctd style=\"text-align:left;font-weight:var(--font-body-weight-bolder)\"\u003e24 dB at 1 kHz\u003c\/td\u003e\u003ctd data-r style=\"text-align:left\"\u003e\u003cstrong\u003eDimensions\u003c\/strong\u003e\u003c\/td\u003e\u003ctd data-r style=\"text-align:left;font-weight:var(--font-body-weight-bolder)\"\u003e122 x 43.5 x 102 mm\u003c\/td\u003e\u003c\/tr\u003e\n  \u003ctr style=\"background-color:transparent;--wb-l:3;--wb-r:7;--wb-lb:transparent;--wb-rb:transparent\"\u003e\u003ctd style=\"text-align:left\"\u003e\u003cstrong\u003eRecommended cartridge impedance\u003c\/strong\u003e\u003c\/td\u003e\u003ctd style=\"text-align:left;font-weight:var(--font-body-weight-bolder)\"\u003e2 - 60\u003c\/td\u003e\u003ctd data-r style=\"text-align:left\"\u003e\u003cstrong\u003eWeight\u003c\/strong\u003e\u003c\/td\u003e\u003ctd data-r style=\"text-align:left;font-weight:var(--font-body-weight-bolder)\"\u003e2 kg\u003c\/td\u003e\u003c\/tr\u003e\n  \u003ctr style=\"background-color:var(--wb-neutral-50);--wb-l:4;--wb-r:8;--wb-lb:var(--wb-neutral-50);--wb-rb:var(--wb-neutral-50)\"\u003e\u003ctd style=\"text-align:left\"\u003e\u003cstrong\u003eOutput impedance\u003c\/strong\u003e\u003c\/td\u003e\u003ctd style=\"text-align:left;font-weight:var(--font-body-weight-bolder)\"\u003e47 kOhms\u003c\/td\u003e\u003ctd data-r colspan=\"2\"\u003e\u003c\/td\u003e\u003c\/tr\u003e\n\u003c\/table\u003e","brand":"Ortofon Hifi","offers":[{"title":"Default Title","offer_id":54361211633939,"sku":"387879","price":899.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0984\/0872\/6803\/files\/c70925d49cf47510e9896da715943fcb87f02b9e_9033_ST_7.jpg?v=1792634513","url":"https:\/\/woodbrass.com\/en\/products\/ortofon-hifi-transformateur-st-7-387879","provider":"Woodbrass.com","version":"1.0","type":"link"}
