FBS Settings

The Settings tab enables selection of the feedback suppressor parameters.

•For Composite View show: — The graph view is set by one of three buttons:

•Only Dynamic FBS Filters

•Only Fixed FBS Filters

•Dynamic & Fixed FBS Filters (default)

•Mode: Q — Adjusts the notch filter Q used by dynamic filters. Similar to the parametric filter Q, it changes the bandwidth of the filter. The default setting can be modified in Tools>Options. The range is from 5 to 65. Larger values provide less change to the audio frequency response while lower values can provide greater feedback suppression but with more impact to the tonal response of the source audio.

Suggested values for specific applications are:

Q Value Application

7Voice with considerable feedback potential

30 Voice with less feedback potential

65 Music with minimal feedback potential

•Attack Time — Sets the time at which dynamic filters are generated after feedback detection. A longer attack time (greater than 200 ms) reduces the chance that music or audio content will trigger the dynamic filters to respond. A shorter attack time (less than 2 ms) reduces the time between when feedback is detected and suppressed.

•Hold Time — Expressed in hours:minutes:seconds up to 9 hours. Hold time sets the time a dynamic filter setting persists before the filter is cleared. When hold time is disabled, dynamic filters persist indefinitely unless cleared manually or the device is power cycled.

Hold time reverts to 00:00:00 when disabled (Enable unchecked).
