Think of it as a 'take-away' device that can reduce the output of a certain range of frequencies.
Use it to tame a boomy room where one note seems to just kill the audience and overpower any other notes/frequencies that you need to be heard.
Unfortunately, on the B-200H and B-200 combo, the notch filter cannot be turned off. It's always on and you can just find an area of freqs that you don't/won't miss. :\
To use it:
Hit the note that is particularly strong or bounces because of room acoustics, and turn the knob until you find the spot where that note is attenuated.
