Most left you will find the input volume control. This will set up the amount of signal going into the delay lines. Remember that overdriving the filter gives an more harmonically rich sound so feel free to experiment with higher levels.
This is where the output mix and panning settings are controlled. The dry (unprocessed) signal and the output of the delay lines have their own output volume and panning knobs.
The dry mix enabled switch is an easy way to stop dry signal coming through. Since a delay is often used as a send effect (inserted on a bus) you wouldn't want dry signal coming through in that case. This is a valuable feature when you are browsing presets which were not specifically designed for this kind of usage. This setting cannot be saved in a preset and therefore will not be altered when browsing presets.
