The Cardioid Microphone Type 4012 is a hi-voltage (130 V) condenser microphone with a linear frequency response from 40Hz to 20kHz (±2dB) and an incredible SPL handling capability of 168dB SPL peak before clipping occurs. Type 4012 is acoustically identical with the popular Type 4011, 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.
