The Distression Program
The Frequency Distression algorithm is extremely ver-
satile at creating frequency compressed or distorted
effects.
Distression is a Mono in (left channel), Dual Mono
output program. The right channel input is ignored and
not processed. These programs can be run in any 480L
configuration.
ALL PRESETS SHOULD BE UTILIZED
“PRE-FADER” FROM THE CONSOLE SOURCE.
This program can be thought of as a low pass/high pass
crossover feeding independent compressor modules.
The high pass compressor feeds a dedicated distortion
module capable of driving various parametric controls.
The Frequency Distression programs represent a wide
variety of different frequency-compressed and dis-
torted effects from the very subtle to the awesome
sublime. Many presets are simply labeled with an
instrument name. This suggests the type of instrument
which should be fed into the effect input.
About the Parameters
Page 1
DST (Distortion Mix - sine/cosine)
DST controls the amount of signal following treble
compression either passing through the distortion
module or bypassing around it.
EXM (Expansion Mix - linear)
EXM controls the amount of signal following treble
compression either passing through all of the distortion
parameters (including the distortion expansion) or by-
passing it. A LARC value of 0 means absolutley no
amount of distorted signal is being passed to XOM.
XOV (Crossover Frequency)
XOV is a6dB/octave low frequency, 12dB/octave high
frequency sliding filter which determines what frequen-
cies are low frequency and high frequency.
HFC (High Frequency Cut)
HFC controls the roll-off characteristics of the distorted
content of the signal.
XOM (Crossover Mix - sine/cosine)
XOM controls the mix of low frequency and high
frequency signals. It is the final mix control in the
program.
DGN (Distortion Gain)
DGN controls the amount of distortion gain up to 6dB.
