What is a Ring Modulator?
A ring modulator mixes your audio
input signal with a carrier oscillator to produce sum and difference
frequencies. Imagine that the ring modulator's carrier oscillator is producing a
500 Hz sine wave, and your input signal is a 100 Hz sine wave. The ring
modulator's output will be a complex waveform. You will hear two pitches: 400 Hz
and 600 Hz. You will not hear your original input or the carrier
oscillator.
The moogerfooger 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.
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, sweeps, swoops, and divebombs.
The moogerfooger ring modulator's control parameters are
signal mix, carrier frequency, LFO rate, and LFO amount. All of the ring modulator.
s parameters can be controlled with expression pedals or external
control voltages as well as by rotary panel controls. Panel switches select LFO
waveform and carrier frequency range. 1/4" jacks are provided for audio input
and output, pedal/control inputs, carrier input, and carrier output.
Features
- FREQUENCY - rotary control, which varies
the carrier frequency over a six-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
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).
- 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 ring modulator 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.
- AUDIO
OUT - 1/4" phone jack - -4 dBm nominal output level.
- 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.
- AUX
AUDIO IN - provides a means of applying an external signal to the ring modulator, in place of the carrier oscillator.
- 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.
- +9V
POWER INPUT - jack - accepts standard 9 volt power adaptors (power adaptor included).
