KEM 970 Cardioid Plane microphone
The KEM970 Cardioid Plane “Line Array” Microphone, developed by the Institute for Radio Technology (IRT) in Munich, was engineered and manufactured by Microtech Gefell.
Consisting of 8 critically spaced capsules, this microphone system achieves a vertical acceptance angle of just 30°, being significantly narrower than shotgun interference-tube technology, whilst avoiding the related phase problems.
The wide cardioid characteristic in the horizontal plane allows the KEM 970 to effectively cover a wide sound stage, e.g a choir, or drama production, whilst being able to record typically at distances up to 3 times that of an omni. The very narrow vertical acceptance angle allows the microphone to deal with ease with unwanted reflected sound from above or below.
Popular applications for this microphone include:
Polar response viewed from side
Polar response from above
KEM 970 developed in co-operation with the "Institute for Broadcast Technology (IRT)" in Munich.
