サンスイ「AU-Fエクストラシリーズ・プリメインアンプ/チューナー」カタログ・AU-Fエクストラシリーズ・昭和57年1月
A booklet for the SANSUI AU-F EXTRA lineup - three integrated DC amplifiers and a tuner under the shared “EXTRA VERSION” branding. The whole series is built around the Super FF circuit: direct-coupled stages without electrolytic capacitors, with a Diamond Differential input. The flagship AU-D907F EXTRA gets a full spread to itself - detailed circuit diagrams, internal photos and measurement graphs. AU-D707F EXTRA and AU-D607F EXTRA follow. The TU-S607 EXTRA is a quartz PLL synthesizer tuner, marketed as tuned to “disc-level sound”. The final spread shows silver-panel variants of the whole lineup plus the GX-A1 rack.

| アンプの創造から成長へそして、技術の到達点が見えてきた。今、音楽の高揚が聴こえる。 | From the creation of the amplifier to its growth - and now the peak of the technology has come into view. Now, the exaltation of music can be heard. |
| とどまることなく進化を続けるアンプテクノロジーのなかで、ひとつの到達点を極めたアンプの姿が見えてきました。AU-FEXTRAシリーズの誕生です。この最新鋭アンプは“音楽の生命感まで伝えきる生きた音楽再生”というサンスイの一貫したポリシィを骨格に、AU-707、AU-607以来、生まれ成長してきた数々の技術のすべてを集約しました。サーキットひとつを見ても、DC時代を拓いたワイドレンジDC、TIM歪ゼロを追求したダイアモンド差動回路、そして、パワー段で発生するあらゆる歪をゼロとしたサンスイ独自の決定的なサーキット、スーパー・フィードフォワード・システムと、時代を代表した技術の成果をあまさず投入。スーパーFF&ダイアモンド差動回路の完成度が極限まで高まったことはいうまでもなく、伝統のうえに最新のアプローチがなされた強力電源部やすでにサンスイのお家芸ともいえるマグネティック・ディストーション対策の徹底化、音楽性を最優先に設計されたMCポジション、そして、サイドパネルとトップパネルにリアルウッドを採用するなどして、ひときわ洗練されたデザイン……いずれをとっても到達の意を込めた“EXTRA”の名にふさわしいものです。その技術の厚さを裏付けるかのように、音が精彩に満ちて弾み、音楽の微妙な陰影までもあまさず再生。サンスイが目標としてきた、純粋に音だけを伝えるアンプの輪郭が浮び上ります。今、サウンドの到達点が聴こえてきます。 | In amplifier technology that never stops evolving, the shape of an amplifier that has reached a summit has come into view. This is the birth of the AU-F EXTRA series. Built on Sansui's consistent policy of "living music reproduction that conveys even the sense of life in the music," this state-of-the-art amplifier gathers all the technologies that have been born and grown since the AU-707 and AU-607. Looking at the circuits alone: the wide-range DC that opened the DC era; the diamond differential circuit that pursued zero TIM distortion; and Sansui's own decisive circuit that reduced to zero every distortion arising in the power stage, the Super Feedforward System - the fruits of technologies that represented their time have been put in without reserve. Not to mention that the Super FF and diamond differential circuits have been perfected to the limit, there is the powerful power supply section, in which the latest approach has been applied on top of tradition; the thorough countermeasures against magnetic distortion, which can already be called Sansui's specialty; the MC position, designed with musicality as the top priority; and a particularly refined design, with real wood adopted for the side and top panels... - any one of them is worthy of the name "EXTRA," which carries the meaning of arrival at a summit. As if to prove the depth of that technology, the sound is full of vividness and spring, reproducing even the subtle shades of the music without reserve. The outline of the amplifier that Sansui has aimed for, one that conveys purely the sound alone, rises into view. Now, the summit of sound can be heard. |
