EDIT: For Phantom II CUSTOM (my original statement here was wrong and misleading) a full digital signal (0dBFS) will give 96dB Sound Pressure Level when 96dB is set in the Max dB SPL field of the config screen. The other volume settings will not change this sensitivity (but will change volume of course).
