DFR is assigned to a channel. When disabled, the DFR filters are turned off.

Assign the DFR block to an input channel or mix bus.
Click this button to prevent both the deployment of new filters and the automatic adjustment
of existing filters. Freeze the DFR to keep it from deploying filters for program material that
contains sounds that closely resemble feedback (such as guitar effects, synthesized tones,
flute or pipe organ). The button appears lighted in blue when the freeze feature is enabled.
During this time, filters remain manually adjustable.
Clears all settings in the DFR block and reverts all filters back to Unlocked (Dynamic).
