The recent development of digital sources capable of greatly enhanced playback resolution brings a wealth of design challenges to the world of high end audio. To meet these demands, innovative solutions to the inherent limitations of current amplifier design had to be developed to fulfill the promise of today's new digital formats. Introducing the Jeff Rowland Design Group Model 112, a digital-age amplifier more than equal to the demands of audio's new millennium.


Featuring a unique two-tiered chassis design in which the power supply is separated from the amplifier circuitry, the Model 112's internal design effectively isolates sensitive signal circuitry from unwanted electromagnetic field contamination. A powerful toroidal power transformer gives the Model 112 the ability to handle even the most difficult loudspeaker loads with ease.

The Model 112 utilizes a machined solid aluminum billet chassis that serves not only as an elegant testament to Jeff Rowland Design Group's well-earned reputation for superior artistic design, but offers a completely non-resonant and RF/EMI shielded platform from with the musical presentation can begin. The amplifier provides a full complement of balanced and single-ended inputs, a unique "wheel lock" binding post for secure loudspeaker cable connection and an on/off DC input jack for home theater applications.

Internally, the Model 112 uses an ultra-fast, integrated circuit input/output topology that couples unquestioned reliability with unparalleled sonic performance. Modern "small geometry" surface mount technology provides the shortest possible signal path to attain unrivaled transparency. A low-impedance "balanced buss" power distribution system delivers clean, accurate DC power directly to critical circuit components. The end result is an amplifier with astonishing dynamics that far exceed its power rating.

Time to open the door to a new musical reality. The Jeff Rowland Design Group Model 112 - a beautiful realization of 21st Century audio

在Hi-End音響廠商中,很少有像Jeff Rowland這麼「守舊」的。許多廠商通常是產品每年翻新一次,媒體才會投以關愛的眼光;擴大機不夠,最好連喇叭、CD唱盤一起做;客人永遠不嫌多,最好從便宜到高價產品通通都有。




Jeff Rowland卻不來這一套,他們只做擴大機,不涉入非專長領域;堅持品質第一原則,寧可高價也不妥協;他們延續一貫聲音理念,不隨波而逐流。已經除役的產品,像是Model 8、9、10後級,Coherence On等前級,在二手市場上都是炙手可熱的器材。我們介紹的Synergy IIi前級原型在1996年就推出了,由於使用結實無共振的基座設計與分離式電源供應,這部前級的傑出表現在全世界獲得極高的評價。1998年這部前級升級為第二代Synergy II,到了2000年採用Coherence前級部分技術(如表面黏著技術,縮短訊號路徑)又改良為Synergy IIi。一部產品幾年來可以在市場上長賣,顧客的支持,就是Jeff Rowland擴大機穩定耐用、好用,而且好聽的最佳證明。



接著在Model 102、112立體聲與201單聲道後級上,Jeff Rowland更大膽的採用了脈波調變式放大(ICEpower R模組),Jeff Rowland是第一個使用ICEpower的Hi End音響廠家。這個模組最早是丹麥Henrik科技大學博士Karsten Neilsen所研發,後來與B&O合作在1999年成立Bang & Olufsen ICEpower公司。Jeff Rowland表示它並不是另外一種D類PWM功放,而是突破性且已成熟的技術,它讓製造廠商以及最終消費者都得到好處,甚至地球也因為它的超高效能而舒緩了全球暖化。在與這種高效能科技結合之中,我們並沒有損失任何東西,特別是音樂性。目前有越來越多廠家加入ICEpower的行列,Jeff Rowland卻有本事將數位擴大機做得優雅柔和與細膩,聲音溫暖而驅動力又強。
