MF-103 是Bob Moog 設計的12 段Phaser 效果器. 可調6 或12 段phaser 線路, 掃描速度可由LFO 控制. 適合搭配吉他, Bass, 鍵盤或聲卡輸出. MF-103 是Bob Moog 設計的12 段Phaser 效果器. 可調6 或12 段phaser 線路, 掃描速度可由LFO 控制. 適合搭配吉他, Bass, 鍵盤或聲卡輸出. MF-103 能稍微改變音色或做出讓你頭昏的極端相位效果. 聲音走純類比通道.
MF-103 12 段 phaser 是 Moog 模組合成器的後代. 適合處理任何樂器輸出或 line level 信號. 內建獨立 6 或 12 段 phaser, 共鳴控制以及可調效果強度及頻率的LFO.
12 段 phaser 控制參數包括掃描頻率(速度), 共鳴, LFO 頻率和LFO 控制強度. 以上參數可用旋鈕, 表情踏板 (MOOG EP-2) 或外接 CV 控制. 面版上可切換 6 或12段 phaser. 1/4” 插孔有聲音信號進出, 踏板/ CV 輸入, LFO 輸出和額外的掃描信號輸入. 堅固的繞道開關 (bypass) 適合桌上或地板操作.
Phaser 是一種梳狀濾波器, 頻譜顯示像梳齒有高有低. Phaser 隨LFO 變化, 改變掃描頻率, 讓聲音泛音增加或減少. 這就產生經典 “whooshing” phaser 效果.
Phaser 可為聲軌加入動感, 讓聲音更活潑. 用 MF-103 能輕易做出旋轉, 閃爍或顫音效果. 用一個音源就能讓聲音充滿舞台空間, 也能模擬喇叭旋轉效果, 甚至創造全新音色.
MF-103 有兩種梳狀濾波功能. 6段 phaser 模式, 頻譜中會出現 3 處凹陷. 12 段 phaser 模式, 頻譜中會出現 6 處凹陷. 這兩種效果聽起來完全不同. 此外, 可調整的回授線路能增加聲音共鳴或改變 phaser 效果強度.

Product Specifications
Features
* RATE rotary control, which varies LFO’s frequency over a 250:1 range.
* AMOUNT rotary control, which adjusts the amount by which the LFO output varies the phaser sweep.
* SWEEP rotary control, which moves the phaser frequency response over a six-octave range.
* RESONANCE rotary control, which adjusts the height and sharpness of the peaks of the phaser frequency response.
* DRIVE rotary control, which adjusts the gain of the audio input to the phaser.
* OUTPUT LEVEL rotary control, which balances the phaser signals with the bypassed signal.
* LO-HI rocker switch, which chooses between the low LFO range (0.01 Hz to 2.5 Hz) and the high LFO range (1.0 Hz to 250 Hz).
* LEVEL, a three-color LED that is used to set the DRIVE control.
* LFO, a LED that indicates the LFO rate.
* BYPASS, a two-color LED that tells whether the phaser is active or bypassed.
* ON/BYPASS, a rugged, smooth-acting ‘stomp switch.’
Jack Panel Features
* AUDIO IN 1/4″ phone jack – accepts any instrument-level or line-level audio signal from -16 dBm to +4 dbm. Input impedance is one megohm.
* AUDIO OUT 1/4″ phone jack – -4 dBm nominal output level. +8 dBm absolute maximum output level. Output impedance is 5,000 ohms.
* AUX OUT 1/4″ phone jack – -4 dBm nominal output level. +8 dBm absolute maximum output level. Output impedance is 5,000 ohms.
* RATE, AMOUNT, SWEEP, RESONANCE, all of which are stereo 1/4″ jacks that accept moogerfooger EP1 (or equivalent) expression pedals, or control voltages from two-circuit or three-circuit 1/4″ jacks.
* SWEEP IN – provides a means of applying an external +/- 2.5 volt control signal to the second 6-section phasing circuit, in place of the LFO. Input impedance is 50,000 ohms.
* LFO OUT 1/4″ phone jack – delivers the LFO waveform (triangular wave; +/- 2.8 volts) for use by other voltage-controlled devices. Output imedance is 600 ohms.
* +9V POWER INPUT jack – accepts standard 9 volt power adaptors (power adaptor included).
