Expander
Widens the dynamic range of the signal. Low-level signals such as noise are diminished. Both mono
channel and stereo channel expanders are provided.
Mono channel expanders have one input, one output, and one KeyIn input. Stereo channel expanders
have two inputs, two outputs, and one KeyIn input.
Double-click a component to open the component editor for it. The parameters are the same for mono
channel and stereo channel components.
