Type 4012 is acoustically identical with the popular Type 4011-TL, but differs in the powering method which enables the 4012 to handle these extreme sound pressure levels. The off-axis characteristics of the 4012 Cardioid Microphone are totally linear, a unique quality which has taken a lot of attention to obtain. So any leakage that occurs from off-axis sound sources is still a faithful reproduction of these sounds, though attenuated according to the true first order cardioid pick-up pattern.
