The last filter (High shelf) is the Treble control.
You can experiment with different response targets and EQ parameters yourself if you'd like, the website is pretty easy to use.
Just make sure that you type in the correct Min/Max Fc/Q/gain values and filter types into the Custom Parametric Eq configurator, otherwise you won't be able to copy the values over to your RME.
You can find these in the User Manual, the ADI Remote App, or directly within your ADI-2.
