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, i.e. sound arriving at different angles won't sound the same. That's no problem in typical studio applications--but it's a severe disadvantage for stereo recording with coincident or closely-spaced pairs of microphones.

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 :)

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 the curves show something that's between a cardioid and a supercardioid (depending on frequency).

- DPA generally publishes frequency response curves "corrected" for a 30 cm measurement distance, while most other major manufacturers use 1 meter. So if you compare DPA's graphs to those of other manufacturers, subtract several dB of low-frequency response from whatever DPA says,

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

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

Sweet! I always preferred the lemo connectors for the B+Ks/DPAs as well! Ive never personally run them, but ive recorded on the same stand as the 4023s many times, and the lemos seem like the way to go! Much easier to coil up the cables at the end of the night, and you can store your 4023 caps/bodies in a small padded case ;)
