The Sound On Sound review says, "an end-address, supercardioid dynamic mic". The description here and on Heil's site says it's cardioid. Can you clarify whether this is cardioid or supercardioid?

TheDGPInteresting question! There's not really a set definition of what makes something supercardioid vs. cardioid. Polar patterns also vary with frequency as well so some microphones may have a narrower pickup pattern at higher frequencies vs. lower frequencies. This is why you get off-axis coloration on directional mics because the frequency response varies depending on the angle of mic to source.
It's sort of a medium pickup pattern. A wide cardioid would have about even response across the front 360 degrees and a hyper or supercardioid would have a lot less. The PR30 seems to be somewhere in between.

nicpopeIs there a single null to the rear of the mic or are there two nulls at 45 degrees from the rear? The Heil site shows a single null in the rear. I'm just confirming that that's the case.

TheDGPShould be a single null. The tighter you make the front the more that rear lobe starts to jut out but in this case straight behind should be total rejection.
