ALM Busy Circuits ALM009 Tangle Quartet 是一款專為 Eurorack 模組化合成器系統設計的高品質四通道線性電壓控制放大器(VCA)。在僅有 8HP 的精巧尺寸中,Tangle Quartet 集結了四個獨立且純淨的線性 VCA,並具備靈活的混音(Mix)功能,是目前市面上最受歡迎的實用型模組之一。
這款模組的核心採用了高品質的 2164 VCA IC,確保在處理訊號時具有極低的雜訊與失真,並且完全消除音訊滲漏(Bleed-free)的困擾,讓您的聲音動態表現極致精準。每個通道均設有獨立的訊號輸入與控制電壓(CV)輸入,並配備專屬的衰減器(Attenuation)旋鈕。當 CV 輸入未插入線材時,CV 輸入會自動內部連接(Normalised)至 5V 電壓,讓旋鈕可以直接作為手動增益(Gain)控制,實現如同傳統混音器般的直覺操作。
Tangle Quartet 的設計巧思在於其靈活的輸出邏輯:它提供四組獨立輸出以及一組總合混音輸出(Mix Output)。當某個通道的獨立輸出未被使用時,該訊號會自動匯入 Mix Output;一旦插入線材提取獨立輸出,該通道便會從總合混音中移除。這種設計讓 Tangle Quartet 不僅是四個獨立的 VCA,更能隨時變身為一個電壓控制混音器(Voltage Controlled Mixer),或是將部分通道用於音訊、部分通道用於處理調變訊號(CV)。
此外,本模組採用 DC-coupled 設計,這意味著它不僅能處理一般的音訊,也能完美精準地處理慢速變化的 CV 訊號,如 LFO 或 Envelope。不論是用於複雜的振幅調變(AM)、手動控制多個聲音來源的比例,還是作為系統末端的總輸出混音,Tangle Quartet 都能以極小的空間佔用提供最強大的功能支援。對於空間有限但追求高品質音訊路徑的模組玩家來說,Tangle Quartet 是建立穩定、乾淨音訊鏈的首選
