for pickup of speech or music at close range (under 50 cm)
cardioid pattern
considerable attenuation of low frequencies
emphasis of high frequencies
for severe acoustic conditions
This microphone type has the same features as the MK 4 S, but in addition emphasizes the frequency response in the 9 kHz region by 4 dB. This effects a further improvement of speech intelligibility, particularly in very reverberant venues such as churches.
The MK 40 or CCM 40 is used primarily for sound reinforcement of speech.
It is not particularly recommended for music recording.
