Attached is a first stab at a shotgun polar response. I tried to hit the following 1kHz response points from the CK98
-5dB @ 60 deg
-20dB @ 90 deg
-15dB @ 180 deg
The ME66 is not quite as directional. It's front lobe is almost exactly the same as a supercard but the rear lobe has more attenuation.
-MIQ
This chart is very misleading, unfortunately.
It only shows a theoretical pattern at a single frequency which is totally meaningless for an interference tube gun mic.
A gun mic. will normally have a super-cardioid capsule, so the low frequency response will be the same as a super-cardioid.
However, it has an interference tube on the front - this will make the microphone more directional as frequency rises.
This is the polar-pattern of the
MKH 60 which shows this effect very clearly:-
(low frequencies up to 1kHz are on the left and high frequencies 2kHz and above are on the right)
This is the polar-pattern of the
ME 66:-
(low frequencies up to 1kHz are on the left and high frequencies 2kHz and above are on the right)
I hope this helps.
