 Threshold slider and field: Sets the threshold level at which the frequency band
defined by the Center Freq. and Bandwidth parameters is divided into upper and
lower frequency ranges.
 Speed slider and field: Sets the modulation frequency for the defined frequency band.
 CF (Center Frequency) Modulation slider and field: Sets the intensity of center
frequency modulation.
 BW (Band Width) Modulation slider and field: Sets the amount of bandwidth
modulation.
 Graphic display: Shows the frequency band defined by the Center Freq. and
Bandwidth parameters.
 Center Freq. (Frequency) knob and field: Sets the center frequency of the frequency
band to be processed by the Spectral Gate.
 Bandwidth knob and field: Sets the bandwidth of the frequency band to be
processed by the Spectral Gate.
 Low Level slider and field: Blends the frequencies of the original signal below the
selected frequency band with the processed signal.
 Super Energy knob and field: Controls the level of the frequency range above the
threshold.
 Sub Energy and field: Controls the level of the frequency range below the threshold.
 High Level slider and field: Blends the frequencies of the original signal above the
selected frequency band with the processed signal.
 Gain slider and field: Adjusts the amount of gain for the final output signal.
Using the Spectral Gate
Using the Center Freq. and Bandwidth parameters, set the frequency band you want to
process using the Spectral Gate. The graphic display visually indicates the band defined
by these two parameters.
Once the frequency band is defined, use the Threshold parameter to set the level
above and below which the frequency band is divided into upper and lower 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 also mix the frequencies from the original signal outside the frequency band
defined by the Center Freq. and Bandwidth with the processed signal. Use the Low
Level slider to blend the bass frequencies below the defined frequency band with the
processed signal, and use the High Level slider to blend in frequencies above the
defined frequency band.
