Assuming you mean "TimeFactor" on Eclipse 4.0B….
These effects are stereo in stereo out. You can set up the Eclipse to be stereo in or mono in.
If you choose mono in, you can then select which of the two channels is the input and feed it to both input channels. This is done explicitly, using I/O Mode under LEVELS – the Eclipse will NOT make any assumptions for this setting based on your other input settings.
