Using the Spectral Gate
One way to familiarize yourself with the operation of the Spectral Gate would be to start
with a drum loop. Set the Center Freq. to its minimum (20 Hz) and the Bandwidth to its
maximum (20,000 Hz) value so that the entire frequency range is processed. Turn up the
Super Energy and Sub Energy knobs, one at a time, then try different Threshold settings.
This should give you a good sense of how different Threshold levels affect the sound of
Super Energy and Sub Energy. When you come across a sound that you like or consider
useful, narrow the Bandwidth drastically, gradually increase the Center Freq., and then
use the Low Level and High Level sliders to mix in some treble and bass from the original
signal. At lower Speed settings, turn up the CF Mod. or BW Mod. knobs.
Follow these steps to acquaint yourself with the Spectral Gate
Set the frequency band you want to process by using the Center Freq. and Bandwidth
The graphic display visually indicates the band defined by these two parameters.
After the frequency band is defined, use the Threshold parameter to set the appropriate
All incoming signals above and below the threshold level are divided into upper and
lower frequency ranges.
Use the Super Energy knob to control the level of the frequencies above the Threshold,
and use the Sub Energy knob to control the level of the frequencies below the Threshold.
You can mix the frequencies that fall outside the frequency band (defined by the Center
Freq. and Bandwidth parameters) with the processed signal.
Use the Low Level slider to blend the frequencies below the defined frequency band
with the processed signal.
Use the High Level slider to blend frequencies above the defined frequency band with
the processed signal.
You can modulate the defined frequency band using the Speed, CF Modulation, and BW
Speed determines the modulation frequency.
CF (Center Frequency) Modulation defines the intensity of the center frequency
BW (Band Width) Modulation controls the amount of bandwidth modulation.
After making your adjustments, you can use the Gain slider to adjust the final output
level of the processed signal.
