Gain Staging Kontakt 6

Dear Community,
my impression of the Kontakt player as a VST plugin is, that the overall levels being fed into the Nuendo Mixer are too low. Where to check the gain staging from Kontakt6 into Nuendo for proper levels? Just take care for the Nuendo side here in this particular forum, so don´t bother with Kontakt.
maybe there is some kind og gain before the VST is sent to the mixer or such…

I would like to restore all to default settings in Nuendo to make sure that the VST PlugIn behaves correctly.
