I almost instantly got an email from a VOXtra reader. He totally nailed me on the fact that most of my advice is geared towards large diaphragm condensers:
I do this for several reasons.
One it helps tame puffs of air as most of them will pass under the microphone, but the voice should travel THROUGH the recording path of the mic.
Also, because of the focus of this mic, I tend to not like pointing the mic at someone's face, as then you're picking up the nasal cavity (not a particularly pleasant source of resonance), and instead try to pick up the talent's chest (by design a much more cavernous source of resonance).
These mics, while built for very rugged conditions, can actually be pretty easily damaged forcing air into them if you're too close. For added protection I tend to use a foam wind sock, as opposed to a pop screen. No particular reason for that, just the way I tend to do it (though sometimes it allows me to be sneaky, and move the mic farther way from talent that like to crowd the mic by scootching the foam towards the end of the mic).
Also, as promo readers tend to wave and conduct their hands around their reads, this distance helps prevent the random smacking of the mic.
Now here's the tricky thing about miking yourself, depending on your space, all of what I just said might be TOTALLY wrong.
I've found good success with this set up, and usually my only adjustments from this initial setup are asking the talent to move a little closer or farther from the mic, but your mileage WILL vary.
I hope that helps, and thanks for the question!
