Levelers are a form of automatic gain controls, which affect long-term average levels. The Leveler differs from the AGC in that it only attenuates the signal, it will not add gain. When the Leveler’s input signal exceeds the threshold, the leveler will attenuate the signal until it reaches the threshold point.
Right-clicking over certain settings will provide a menu of additional options. Control Dialog Boxes for Levelers can be minimized to create user control surfaces (see Customizing Component Objects).
