SSL (Solid State Logic) Super Analogue Mic Preamplifier X-Rack Module-XR621

瓦器錄音室Studio B的設備建置目標以60~90年代間的英國、美國與德國的經典好聲音為建置藍本，格外針對聲音源的採樣環節多所琢磨，在麥克風以及麥克風前級上持續投入巨資以確保擁有各式享譽國際經典Console的經典聲音，舉凡SSL、NEVE、API、Focusrite、Tascam、Euphonix、Helios、Manley、Millennia...
這些動輒台幣數百上千萬元的Console，MuScene Studio以模組化的方式完整蒐羅其原始的經典聲音特質;透過模組內部與原始Console完全相同的零組件、線路設計，確保每個Console Channel上所擁有的character and tone被完整的複製到了微型化的Module裡，如此在僅僅只有五十平方米左右的錄音室裡卻能擁有十餘種大型經典Console的原始音色與音質。

MuScene Studio此次引進 SSL Super Analogue Mic Preamplifier X-Rack Module-XR621，把英國經典的SSL XL9000 J/K系列大尺寸類比Console的原始音質、音色給完整複製進了MuScene Studio Studio B，期許能提供給尋求此款Console的完美音質追尋者一個極具性價比的解決方案。

國內除了極少數規模數錢萬、上億元的大型錄音室、成音後期處理室以外，一般人極難擁有或維持SSL XL9000 J/K系列的Console;龐大的電力消耗、天價的維修與建置費用、頂級的電子原件...導致時下流行的Project/Home Studio少有SSL經典的好聲音。

SSL Super Analogue Mic Preamplifier XR621具備與XL9000 J/K系列大尺寸類比Console Mic Pre模組完全相同的電路設計、放大迴路與電子零組件原件，故此能完整複製其原始Mic Pre音色，但也因而導致SSL Mic Pre Module的價格極度昂貴;相較於原始的XL9000系列
Console，價格則是明顯的親民的多。

如此經典的Mic Pre當然也具備了無與倫比的表現參數，相關資料如下:
