taken striaght from the manual on thier site
Pad Switch (-10db switch)
Where a pad switch is fitted, this should only be used when the microphone is being used to record
exceptionally loud sound sources that risk overloading the microphone preamplifier to which the
microphone is connected, even when set to its minimum gain setting.
Low Cut (roll off switch)
Where fitted, the Low Cut switch activates a high-pass filter that reduces the amount of low frequencies in
the output signal from the microphone. Low Cut may be used to reduce the amount of bass boost caused
by the proximity effect when working very close to the microphone or to to exclude low frequency
signals, such as traffic and floor vibrations where the signal being recorded has little or no deep bass
content.
experiment with it. i recorded some piano yesterday and im loving this mic
