A rule like that would rarely need be broken, because very few actual hypercardioid microphones exist. Most microphones that are said to have a hypercardioid pattern are closer to being supercardioids. That's true of Neumann, AKG, Beyer and others, while Schoeps and Sennheiser call theirs supercardioids (although their actual directional patterns are hardly any different from those of Neumann or AKG).

The polar diagram of a true hypercardioid would look much like that of a figure-8, but with a somewhat shrunken rear lobe; its sensitivity at 180° is only 6 dB less than its sensitivity at 0°. (For a true supercardioid that difference is around 11.7 dB.)

--Just one note about the polar diagrams that were posted earlier in this thread, which as someone pointed out, are NOT those of the model that this thread is mainly about: Any variation in the pattern at different frequencies means that for different angles of sound incidence (arrival), the microphone will have different frequency response curves. That's no problem for typical studio applications (spot miking), but it's a disadvantage for stereo recording with coincident or closely-spaced pairs of microphones, since those recording methods are based on the microphones having essentially identical frequency response at all angles of incidence.

--best regards

No, I don't think you would, since the polar diagram posted earlier in this thread doesn't indicate anything close to a hypercardioid pattern. Rather, the pattern appears to be somewhere between cardioid and supercardioid, depending on the frequency.


DPA hasn't posted a diagram for the new 4018 yet. I think the diagram posted was for their 4018v vocal mic. So maybe the 4018 pattern will be different

But thanks for the explanation anyway :)

scb, many thanks for pointing that out. I'll change my earlier posting, because I don't want to be saying something that's untrue of the 4018. That model is the subject here, and people could easily misunderstand.

The people who quoted my message back, could you please edit that out? (It's not necessary to quote entire messages back on a threaded discussion board anyway--people can see the message that you're replying to.)

I just heard that the 4018 caps are now available on a limited basis (guessing for top customers). Prices and specs should be out very soon!

^^^ Cool!  Are you going to check out the strain relief on the active cables too?

they mentioned possibly a 3rd kind of active cable. Since the 2 announced are side and rear cable, I have to wonder if there will be a lemo one....

pricing for the 4018 seems to be the same as the 4011

If what's just above this message is DPA's set of polar diagrams for the new microphone, then scb, you wouldn't need to break your "no hypers" pledge for this microphone, because it isn't a hypercardioid. Rather, the curves show it as being somewhere between a cardioid and a supercardioid, depending on frequency.

In addition, DPA generally publishes frequency response curves that are corrected for a 30 cm (or about 14") measurement distance, while the other major manufacturers generally use 1 meter. So for directional (pressure gradient) microphones, such graphs include more bass boost from proximity effect than other manufacturers' graphs do. This makes the microphones appear to have better low-frequency response than if DPA used the same measurement approach as the other major manufacturers.

While DPA is admirably open about how they make their measurements, I don't know how many readers realize that they should mentally subtract several dB of low-frequency response from what is shown in these graphs, unless 14" is really a typical miking distance for them. That is, assuming that these are 30 cm graphs as has been DPA's usual practice in the past.

This doesn't apply to their omnidirectional microphones, of course, which are pressure transducers.

(For that matter, the other manufacturers' 1-meter distances also give the low end of their directional microphones a small boost over what would really be picked up in a free-field situation, but at least those curves can be fairly compared to one another since the measuring distance is the same.)

I guess I should change the thread title - DPA calls it a Supercardioid :)

and thanks again for the excellent information!

I've been told there may be a MMP-EL "lemo" style active cable in early 2014. Not sure on the name, but since MMP-ES is "side" and MMP-ER is "rear," I assume the lemo might be MMP-EL
