Filters

Graph setup window. Each mic/line input has four configurable filters that can be
used as filters or equalizers. By default, they are not enabled and the filter types are
not defined. Below is a description of each feature in the window.
Active Filter
Active Filter selects among filters on the graph. Note that no filters exist until you
click Add Filter (see Figure 3.26).
