Second, I said that the “omni” switch setting probably wasn’t really going to be actually “omni,” but was more likely to be figure-eight or the like. This was in response to both the capsule design, grille design, and older pictures of the circuit board which appeared to indicate that. In testing, I discovered that I was mistaken<\/em> – as you can see here, levels as seen in waveforms made by holding a tone generator at the four cardinal directions remain constant. But read on, after the graphs, because there’s a catch:<\/p>\n And here’s the same test, with the mic set to cardioid:<\/p>\n And here’s an M-Audio Nova, same conditions, for comparison:<\/p>\n The total pickup is certainly omnidirectional. But this is not<\/em> a true basket head on this thing, there are support brackets on the left and right sides, and that does<\/em> affect tone! High-end harmonics definitely<\/em> fall off on the left and right sides.<\/p>\n So while it does qualify as an omnidirectional microphone in “omni” mode, I’d have to call it flawed in that mode, and use something else – like an Oktava 012 with the omnidirectional head, which is built for true omnidirectional pickup and does not<\/em> exhibit this behaviour.<\/p>\n Alternately, I suppose it might be usable in that mode if you’re recording someone who is a tad screechy – aim the wrong side at the performer and presto, fewer high harmonics.
