RING MOD/DISTORTION
Pressing RING MOD/DISTORTION in the main MULTIFX page will show this screen:
A ring modulator is a device with two inputs and one output. One input carries the audio source
and the other a sine wave signal of variable frequency. The two signals are modulated to produce
sum and difference frequencies. For example, if one input is a sine wave of 500Hz and the other is
a sine wave of 750Hz, the output will carry the original signals AND the sum (1250Hz) and the
difference (250Hz). The result is enharmonic and ‘clangy’ sounds. With harmonically rich sounds
fed to the ring modulator, the sounds can be even more discordant.
Other effects are also possible. If the modulating oscillator’s frequency is low, the effect will be a
tremolo effect. At frequencies of 100Hz or so, you can produce the famous ‘dalek’ voices and other
robotic, metallic effects on speech. At high frequencies, the results are rather unpredictable and
largely depend on the audio input signal but, basically, they can best be described as discordant
and clangourous. The parameters are:
RMOD FREQUENCY This sets the frequency of the sine wave modulation signal. It is variable
from 1Hz - 5000Hz
RMOD DEPTH Sets the depth of the ring modulation effect.
The distortion processor offers variable distortion from mild clipping to heavy metal filth! The
parameters are:
DISTORTION Sets the amount of distortion
OUTPUT LEVEL Sets the output level of the distortion processor. This can be used to
compensate for the high gain you get with high DISTORTION levels.
The ACTIVE switch on F10 allows you to bypass the RMOD/DISTORTION effect.
