These microphones are tailored for
people speaking in loud environments,
an application primarily all about speech
intelligibility. They are therefore used
in close proximity and lower frequen-
cies are attenuated. This enables envi-
ronmental noises to be faded out and
compensates for the “proximity effect”,
avoiding the voice having a booming,
artificial quality which would be tiring
and reduce speech intelligibility
CCM 4S:
– cardioid for a pickup distance of
approx. 50 cm
CCM 40:
– cardioid for a pickup distance of
approx. 50 cm
– high-frequency emphasis for better
speech intelligibility in reveberant
venues (e.g. churches)
CCM 4VXS:
– cardioid for a pickup distance of less
than 10 cm
– lateral pickup
– high-frequency emphasis for better
speech intelligibility

cardioids for
