Feedback Suppressor (Inputs only)
The Feedback Suppressor (FBS) provides automatic feedback control. This is done by constantly monitoring the audio
and automatically adjusting any one of 12 lters to remove feedback. Notch and Parametric Filter types are used, depending on
the characteristics of the feedback. Because feedback suppression is more effective on an single input rather than an output mix
of channels, the FBS is only available on inputs, and only at the 48 kHz sampling rate. The FBS is DSP resource-intensive, so if
a FBS is used, the FIR lter on the same channel's output gets disabled in order to allow the DSP power necessary for the FBS.
Filter Parameters
Filter (number) - Current Active Filter (highlighted).
Filter In/Out - Green = Filter In (engaged), Red = Filter Out (disengaged).
Filter Lock - Locks Filter at its current setting, when locked the detector will no longer adjust the lter.
Filter Mode - There are three lter modes:
Restricted: Filter will only broaden or deepen.
Floating: Detector may release lter after oat time or modify lter type.
PEQ: Detector will not modify the lter however the user may control the lter.
Type - Selected Filter Type (Parametric or Notch).
Frequency - Selected Filter Center/Corner frequency.
Level - Selected Filter Boost/Cut amplitude.
Bandwidth - Selected Filter Bandwidth (or Q).
Feedback Detector Parameters
Sensitivity - Detector Sensitivity to feedback
Float Time - Time before a oating lter will start to release.
