Since those are derived from the internal re-clocking process they have the same ultra-low jitter qualities as the basic clock signal embedded in the audio signals

a selectable high-pass filter at 75Hz is available which will prevent low-end noise such as air conditioners and traffic from being recorded

which can be further shaped with the use of two switches on the rear side of the microphone

and a slight boost in the highest frequencies that lends presence and freshness to the voice

while the 100 Hz setting is optimized for speech and vocals (where 100 Hz corresponds to the lowest notes of a baritone)
