Erica Synths Black VCF Coupler 是專為 Black High Pass VCF 與 Black Low Pass VCF 設計的衛星擴展模組。單獨使用 HP VCF 與 LP VCF 時,各模組獨立作為高通與低通濾波器運作;接入 VCF Coupler 後,三模組協同形成完整的多模式濾波系統,解鎖帶通(Bandpass)與帶阻(Band Reject / Notch)兩種額外濾波模式,兩種模式的中心頻率(Center Frequency)與頻寬(Bandwidth)均可手動及 CV 控制。Coupler 的加入不影響 HP VCF 與 LP VCF 的獨立操作能力,三模組可隨時拆離各自運用,形成高度靈活的模組化濾波生態。
解鎖帶通與帶阻濾波模式
・Black HP VCF + LP VCF + VCF Coupler 三模組搭配後,整體系統新增以下兩種濾波模式:
・帶通(Bandpass):僅允許設定頻率範圍內的頻率通過,頻帶以外的高頻與低頻均被衰減
・帶阻(Band Reject / Notch):精確消除特定頻率範圍,其餘頻率完整保留,適合頻率梳狀染色與諧振移除
中心頻率與頻寬獨立控制
・帶通與帶阻模式的中心頻率(Center Frequency)可手動旋鈕及 CV 控制,掃動濾波器位置
・頻寬(Bandwidth / Q)可手動調整,從極窄銳利的諧振峰至寬頻段平滑過渡均可設定
・所有參數均支援手動與 CV 雙重控制,可進行動態的頻譜塑造
不影響原有模組獨立性
・接入 Coupler 後,Black HP VCF 與 Black LP VCF 仍可作為獨立的高通與低通濾波器各自運作
・Coupler 提供額外功能路徑,不強制改變任何既有模組的訊號路由
