Re: A kind of microphone
Posted: Tue Jun 18, 2019 6:32 pmSorry Rex, we old pharts who have been in the audio biz can run indefinitely and maybe not quite on the original topic, either....quite.
Those specs make it look like a good mic for many uses, and it's indeed cute - which matter to some.
The key statement to me was "good about feedback" which indicates two things (maybe). The patern's not bad - OK, and that frequency response they plot isn't super-smoothed quite as much as most are.
Those who do live PA work are real sensitive to good pattern (also for rejecting room reverb, usually) but a "smooth" curve - doesn't have to be "flat" and these aren't, no biggie, actually. In real life, even in perfect anechoic chambers, most transducers may average out fairly flat on a 1/3 or 1/2 octave smoothed curve (which is what's usually published), but in reality have 10 or even 20 db peaks or dips hidden by that smoothing - and those result in horrible live performance as PA mics, as it's the gain at that little peak and bingo - feedback, even when the rest of the range can barely be heard.
This is in fact the reason I told the story about measuring impulse response, as it's a fast way to show that up along with an FFT.
