Maybe you are confusing things by using the term pre fader when this option doesn't exist in Cubase.
The input gain will affect the meter in both "Post Fader" & "Post Panner" settings.
It will not make any difference when metering is set to "Input"
Oh, dear, it's going to be a tougher transition from C6.5 than I thought
It's exactly the same
