MF-101 Lowpass Filter

種類 效果器

Maceo Parker Improv Experiment w/Moogerfoogers

MF-101 低通濾波器, 是原始MOOG 模組合成器的後代. 包括voltage-controlled控制低通濾波器和envelop follower 兩個部分, 可處理吉他或樂器信號.

這個moogerfooger 濾波器控制參數包括 混音, 截斷頻率Cutoff, 共鳴Resonance , Envelop 控制量等. 所有參數都能用渴望被轉的旋鈕, 表情踏板或外部CV 控制. 面板上還可切換2 pole 或4 pole, envelop follower 快速或緩慢.  1/4” 插孔為聲音進出, 控制踏板/ CV 輸入, envelop follower 輸出. 耐用的bypass 開關適合桌上或腳踩操作.

低通濾波器lowpass filter 可移除聲音中的高頻. 讓聲音變柔或悶掉. 截斷頻率轉低, 聲音聽起來會更悶. MF-101 像遮光廉, 拉下一點遮掉窗戶上方, 再拉遮掉一半, 拉到底遮掉整個窗戶, 等於把所有頻率檔掉. 調大共鳴Resonance控制, 可增加接近截斷頻率泛音的音量. Moogerfooger 濾波器處理聲音能力和經典minimoog 和Moog 模組合成器上的濾波器一樣

MF-101 Lowpass Filter
Product Specifications

* CUTOFF rotary control, which varies the filter’s cutoff frequency over an eight-octave range.
* RESONANCE rotary control, which varies the shape of the filter’s response, from pure lowpass to actual oscillation.
* ENVELOPE AMOUNT rotary control, which adjusts the amount that the input signal’s envelope sweeps the filter cutoff frequency.
* MIX rotary control, which crossfades continuously from unfiltered to filtered audio.
* DRIVE rotary control, which adjusts the gain of the audio input.
* SMOOTH-FAST rocker switch, which chooses between smooth and fast envelope follower response.
* 2-POLE 4-POLE rocker switch, which chooses between 2-pole (bright) and 4-pole (deep) filter frequency
* response.
* LEVEL, a three-color LED that is used to set the DRIVE control.
* ENV, a LED that indicates the strength of the envelope voltage.
* BYPASS, a two-color LED that tells whether the filter is on or bypassed.
* ON/BYPASS, a rugged, smooth-acting ‘stomp switch.’
