Depth
This indicates the gain reduction of the selected filter. The range of available
gain values is between 0db and –18dB in 0.5dB increments, with a default
setting of 0dB.
Type
This indicates the bandwidth type of the selected filter. Select High Q or Low
Q from the pull-down menu. Low Q is the default value.
Feedback Filters
The feedback filters controls appear as a row of LED-style indicators. You
can specify the number of fixed versus dynamic filters by sliding the red
brackets left and right with the mouse. Active filters are indicated in yellow and
appear in the Response Graph. Refer to the Filter Allocation section on page
59 for further explanation.
FIXED
These filters remain at their current frequencies regardless of
newly detected feedback.
DYNAMIC
These filters are automatically deployed by the DFR when it
detects feedback.
Lock
Click this button to prevent both the deployment of new filters and the deepening of existing filters. Use this option to
keep the DFR from deploying filters for program material that contains desired feedback or sounds closely
resembling feedback (such as guitar effects, synthesized tones, or pipe organ).

Snapshot
This feature allows you to freeze an image of the current response curve by clicking
the [Take] button and then display it in the background for comparison by clicking the
[Show] button. The [Show] button appears lighted in green when the snapshot is
displayed. For a more in-depth description of the snapshot feature, see the Snapshots
section on page 33.
