Active Filter

The following sections describe how to configure and activate input channel filters.

Use the Active Filter drop-down list to select among active filters. Selecting a filter highlights its node on the graph and displays its current settings. You can configure up to four active filters per input channel.

NOTE: There are no filters configured by default. Press the Add Filter button to create a filter for the input channel. When you add a filter, it appears in the Active Filter drop-down list, and on the active filter graph.

In graph view, you can click on a filter node and drag it to the desired location on the graph. The setting fields immediately reflect changes made by dragging filter nodes.
