MK 41S, CCM 41 S

– for pickup of speech or music at close

range (under 50 cm)

– supercardioid directional pattern which

is highly uniform throughout the fre-

quency range

– considerable attenuation of low frequencies

– excellent suppression of ambient noise

In its frequency response and in

the range of its applications this

microphone type resembles the

MK 4S or CCM 4S, but due to its

greater directivity it attenuates

reverberant sound further, and it is

less prone to feedback.

The rolloff of its low-frequency

response is offset by proximity

effect at close working distances.
