Vent Normalization Instructions: (note: may not be available for every computer/version) This should help ensure that folks are not too loud/soft when you hear them on vent.
Go to Setup
Enable Direct Sound
Select the SFX Button
Select Compressor and click Add.
Under Compressor Properties use the following settings:
Gain = Adjust for how loud you want people to be. (I use 15)

Threshold = Around -30
Ratio = 100
Pre delay = 4.0
