Setting kMultiChannelMixerParam_Volume above 1

In the docs and header  the maximum value of kMultiChannelMixerParam_Volume is 1.0 (unity gain) 

   However,  i've noticed that passing values above 1  seems to increase the volume a little extra.  Values above 2 seem to negate this effect.

AudioUnitSetParameter(self.micmodule.submixerUnit,kMultiChannelMixerParam_Volume,kAudioUnitScope_Input, 0, 2.0 ,0);

I would like to make use of this boost in my soundboard app   -  is there an actual amplification of the signal happening here?
