Width
This adjusts the MAXIMUM width, in octaves, for filters set by FBX. The width of filters set by FBX is variable, but will never exceed the width set here, except for very low frequencies.
Depth
This adjusts the MAXIMUM depth, in dB, for filters set by FBX. The depth of filters set by FBX is variable, but will never exceed the depth set here.
Persistence
This adjusts how long feedback must be present for before FBX will set a filter. Longer values mean feedback will take longer to be filtered out.
Sensitivity
Sensitivity adjusts the level at which harmonics inhibit filters from being set. Use lower values when there may be pure tones in the program, higher values for speech.
Dynamic Filter Timer
This option allows you to set a time upon which Dynamic filters will automatically release. Factory default setting is O. At this setting, Dynamic filters will not release until they are needed to eliminate new feedback. This occurs only when all Dynamic filters have previously been set.
Factory Defaults Button
Clicking here will restore all FBX parameters to the factory default settings.
The FBX parameters dialog allows you to adjust the FBX to match your particular application.
