RG-1 Reference Groove 指標 黑膠唱盤與 Reference Tonearm - New Gen 新指標 唱臂,可能是世界上第一套透過黑膠唱片,讓聽眾體驗最接近錄音室原裝母帶的參考級模擬播放系統。無論音樂表現,準確度,細節交待,以至背景寧靜度抑或栩栩如生的動態表現,皆達至首屈一指的最高境界。最終結果就是為黑膠唱片營造靜如深海的播放背景,造就樂手們所彈奏的每個音符,歌者所獻唱的每句歌詞,同樣充滿生命力。
極高剛性碳化鎢主軸與航天級磷青銅軸套
別出心裁的 RG-1 主軸部份包括航天級磷青銅軸套,超精度碳化鎢主軸和氮化矽滾珠,符合最高工業標準要求的加工處理,確保主軸達致完美的靜音運行。加上廠方獨門研發,分別以具有抗磨、消泡、疏水物質和冷卻劑成份配製而成 L-1G 專用潤滑油,長期保持最佳性能。
瑞士精製24極同步馬達
構成 RG-1 的動力核心,是一枚瑞士精製24極同步馬達,組裝時將會率先固定於動用原件鋁磚挖空製作的屏蔽外套裡,底部加入縮醛製墊片及獨立軸承系統,作為跟動用6組螺絲直接固定於底盤之上,配備獨立吸震素材的大型縮醛基座相連。每當起動時,鋁製屏蔽外套身上的橙色矽膠帶,將負責管轄整個馬達的水平擺動範圍,從而抵消過多的驅動力,確保皮帶擁有恆定張力,免除諧震的產生機會。配合最新改良,提供 33.3 / 45 兩段播放速度的 Tempo Motor Drive 拍子 馬達驅動系統及 Pulse-HB 人手精製電源過機線,全面發揮 RG-1 的應有實力。
締造線性阻尼和一體化無共振結構的兩件頭鋁轉盤
轉盤環節分別由2件動用 CNC 數控車床進行加工的鋁材生產,配合6枚不銹鋼螺絲組裝而成,締造線性阻尼和一體化無共振結構,同時實現了最佳慣性重量比,令轉速得以保持在恆定水平。轉盤底部的中央位置設有跟超精度碳化鎢主軸相連的定位支點,有助消除主軸耦合接點上的不平均壓力,從而達致最高性能及耐用效果。轉盤表面鑲有具備校聲作用,嚴選2mm厚黑色亞加力生產的唱片墊。主軸頂部採用活動式設計,廠方建議用家把唱片放在轉盤之後,先把主軸頂部抽起才進行播放,此舉能防止不必要諧震漫延到唱片,從而影響唱針的循跡能力。
底座以不同厚度亞加力板及隔離組件所構成
結構上,RG-1 選用不同厚度的亞加力板,作為多層式無諧振底座的生產素材,取其一致的剛性及抗振效能。所有亞加力板將會動用 CNC 電腦數控車床進行切割,並透過自家研發,設計頗為複雜的隔離組件作為耦合素材,成功為唱臂、唱頭和唱片提供了最佳的展示實力平台。讓聽眾每次使用 RG-1 播放心愛曲目時,都會成為念念不忘,回味無窮的音樂體驗。
