MF-102 SPECIFICATIONS

DESCRIPTION:

Analog effects module incorporating three functions: ring modulator, carrier oscillator,
and low-frequency modulating oscillator (LFO).

FRONT PANEL FEATURES:
FREQUENCY rotary control, which varies the carrier frequency over a seven-octave
range.
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.

DRIVE rotary control, which adjusts the gain of the audio input.
SQUARE-SINE rocker switch, which chooses between square and sine-like LFO
waveforms.
LO-HI rocker switch, which chooses between the low frequency carrier range (0.6 Hz to

80 Hz) and the high frequency carrier range (30 Hz to 4,000 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 indicator LED that tells whether the filter is on 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 1 megohm.
AUDIO OUT 1/4" phone jack - -4 dBm nominal output level. Output impedance is 600

ohms.
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.

CARRIER IN - provides a means of applying an external –4 dBm (0.5 volt RMS) signal to
the ring modulator, in place of the carrier oscillator. Input impedance is 1 megohm.
LFO OUT jack - delivers the LFO voltage (±1.5 volts) for use by other voltage-controlled
devices. Output impedance is 600 ohms.

CARRIER OUT jack - delivers the carrier signal (±1.25 volts) for use by other devices.
Output impedance is 600 ohms.
