AudioUnits filters

Hi (and Happy New Year)!
Does somebody could describe how signals over 0db -resulting of the use of AudioUnit filter to boost a frequency range- are processed by Audirvana?
As an example, if I apply a gain of +6dB at 30hz, tacking into account the dynamic compression of most of the pop and rock songs, I may certainly overpass the “0db level”. In this case, what’s the “behave” of Audirvana: does it limit and clamp the signal at 0db using limiter/compression mechanism? Should I expect to get a sensitive increase of signal distortion? else?
