Xaoc Devices Lublin 是一款高品質的雙通道 Voltage-Controlled Amplifier(VCA)模組,專為 Eurorack 模組系統設計。其核心特色在於結合了精準、低雜訊的 VCA 電路,以及能模擬 vactrol 動態行為的 ping 輸入設計,使其在動態塑形、節奏聲音與音量包絡生成方面展現出高度音樂性。
Lublin 的每一個通道皆為完全獨立、結構相同的 VCA,具備 exponential CV 響應,並額外配置一組專用的 Ping Input。這個 ping 輸入並非單純的觸發,而是透過精心設計的全類比電路,模擬傳統 vactrol 在受激發時的增益變化行為,使聲音呈現出類似撥弦或敲擊類聲學樂器的自然衰減特性。
與傳統 Lowpass Gate(LPG) 不同的是,Lublin 並不會隨著音量衰減而削減高頻內容,而是 僅針對增益進行控制,完整保留頻寬。這使得 Lublin 特別適合處理諧波結構豐富的聲音來源,例如 Xaoc Devices 的 Odessa additive VCO,或其他數位振盪器、複雜波形與疊加合成聲源。
為了避免類 vactrol 行為過於單一,Lublin 提供了三種不同的 ping 響應模式(natural、shortened、prolonged),並搭配一顆可變電位器,讓使用者能在自然衰減、短促打擊感與拉長壓縮式包絡之間自由調整。這不僅能用來創造類似 bongo、木箱鼓等打擊聲,也能塑造厚實、緊縮感十足的 kick 或低頻動態形狀。
在電路設計上,Lublin 採用了 以 CV 飽和為核心的增益限制機制,確保即使在高增益或強烈調變條件下,也不會因音訊放大過度而產生不必要的失真。這讓模組在維持音色乾淨度的同時,仍保有足夠的動態範圍。
此外,Lublin 為 DC-coupled 設計,代表它不僅能處理音訊訊號,也能安全、精準地用於 CV 訊號處理,例如動態調變、包絡塑形、LFO 電壓控制等用途,使其成為一顆在聲音與控制訊號之間都極具實用性的 VCA 模組。
