Hi!
When recording exterior sound with moderate wind using my camera mounted AT897 shotgun mic and wind sok for the purpose of going to 5.1 in post do I engage the mic 80Hz 12dB/octave flat roll off switch? And if so how can I prevent low end rumble/distortion in the aquisition?
Thanks for your input...

You can allways ad a lowcut in post, doing it in the mic gives you a little more headroom on the recording device. 80hz is pretty low, with only 12db/oct you'll hear some hz further down. I don't know what could happen under 80hz that's worth to record, explosions, city-rumble, indutrial-noise, big ship leaving harbor, or music, if it's for human voice cut it at 80hz you don't need to go lower...

how can I prevent low end rumble/distortion in the aquisition?

Get a good windshield and lowcut at 80hz
