Doepfer A-145-2 經典精簡版低頻震盪器

Doepfer A-145-2 是一款隸屬於 Slim Line 系列的低頻振盪器（Low Frequency Oscillator, LFO），專為模組化合成器玩家設計。它繼承了經典 A-145-1 的所有核心功能，但在面板空間上進行了極致優化，僅占用 4 HP 的空間，是小型系統或空間有限機櫃的理想選擇。

這款 LFO 模組能夠產生極寬頻率範圍的週期性控制電壓（CV）。內建三段頻率切換開關，頻率跨度極大：從最慢數分鐘循環一次的極低頻，到最高可達 4-5 kHz 的音頻範圍（Audio Frequency），讓它不僅能用於緩慢的濾波器掃描，也能作為簡單的音訊來源或進行音訊速率調變（Audio Rate Modulation）。

A-145-2 提供五種獨立波形輸出：鋸齒波（Sawtooth）、反向鋸齒波（Inverted Sawtooth）、三角波（Triangle）、正弦波（Sine）以及方波（Square）。使用者可以同時將這些波形發送至不同的目的地，例如調變 VCO 的脈衝寬度（PWM）或頻率（FM）、調整 VCF 的截止頻率（Cut-off Frequency），或是透過 VCA 進行振幅調變（AM）。

相較於前代，A-145-2 除了將寬度縮減一半，更增加了方波與鋸齒波的 LED 狀態指示燈，讓使用者能直觀觀察調變週期與訊號強度。此外，同步輸入（Reset Input）功能允許您透過外部門檻訊號（Gate）或時脈（Clock）重置 LFO 週期，確保調變節奏與樂曲完美同步。
