Exteriors settings (SE 300)

If you can hear a low rumble from the wind or when you move the mic around and hear that rumble. Then it's time to kick in the low cut. Combine the lowcut with affective wind protection makes the AKG a nice mic for outdoor use. My fav place to use the CK93 is interior car. The lowcut filters out frequencies below whatever the cutoff freq is. It might be 75hz. I forget what it is on the SE300.

Bass roll-off basically takes the frequencies below a certain level, typically 80 or 100Hz or so, and lowers the volume more and more as the frequencies get lower, generally by 3dB per octave.

Hate to be the bloke that brings this one up. But in terms of what freq range and by how much the mic actually cuts you should look at your manual that came with the mic. If not you can find it online for sure. My teacher in audio school always told us: RTFM!

Your question should be more along the lines of when should you NOT use the low cut. Wind noise can be a factor even indoors with a stationary mic mounted on a podium or desk and the speaker talking into it - breath exhalation and nose snorts is wind. Low frequency rumble from footsteps, air conditioning units on the roof, passing trucks, etc can sneak in up the mic stand. One of the problems that can occur is that some of these very low frequency sounds can actually be louder than you think they are because of the falloff of the ear's sensitivity - you can't hear 'em but they're there and the mic CAN hear 'em, sometimes strong enough to cause overload or clipping, etc. So many workers will keep the low cut turned on all the time, turning it off only when recording sounds that have signifigant low freqency elements like drums and other muscial instruments, male operatic vocals, etc.
