The MF-102 Ring Modulator is a direct descendant of the original Moog modular synthesizers. It contains three complete modular functions: a ring modulator, a voltage-controlled carrier oscillator, and voltage-contolled dual-waveform LFO. It can be used to process any instrument-level to line-level signal.
A ring modulator produces sum and difference frequencies between the audio input and a carrier oscillator. The ring modulator's LFO can be used to modulate the carrier frequency. The moogerfooger ring modulator can create effects ranging from subtle tremolo to harmonically rich distortion, gong-like sounds, sweeps, swoops, and divebombs. It can be subtle, or outlandish in it's use - you decide!
Rate rotary control, which varies the LFO's frequency from 0.1 Hz to 25 Hz
LFO amount rotary control, which adjusts the amount that the LFO output sweeps the carrier oscillator
Mix rotary control, which crossfades continuously from unmodulated to modulated audio
All those parameters are also controllables via CV external signals or pedals (6.35" mono or stereo jack)
Level, a three-color LED that is used to set the DRIVE control
Square-sine rocker switch, which chooses the LFO waveform
Lo-hi rocker switch, which chooses between the low frequency carrier range (2 Hz to 130 Hz) and the high frequency carrier range (60 Hz to 4,000 Hz)
Bypass, a two-color LED that tells whether the ring modulator is on or bypassed
Audio in 1/4" phone jack - accepts any instrument-level or line-level audio signal from -16 dBm to +4 dbm
Aux audio in - provides a means of applying an external signal to the ring modulator, in place of the carrier oscillator
Audio out 1/4" phone jack - -4 dBm nominal output level
LFO out jack - delivers the LFO voltage for use by other voltage-controlled devices
Carrier out jack - delivers the carrier signal for use by other devices
Frequency, Rate, LFO amount, mix, 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
+9V power input jack - accepts standard 9 volt power adaptors (power adaptor included)
Case black panel with hardwood sides - classic analog appearance.
Dimensions 9" x 6" x 2-1/2" (228.6 x 152.4 x 63.5mm)
Weight 2lbs (0.90kg)
