They call it hypercardioid but it looks more like a short shotgun.
Part of the CMS series, in conjunction with the C451 pre-amp, the CK8 has a narrow acceptance angle making it suitable for 'float' use or for medium distance recording. Please note that this microphone exhibits a small pick-up lobe to the rear as well.
