– wide cardioids
– polar pattern very well maintained
throughout the frequency range
– a favorable compromise between
omni (good low-frequency response)
and cardioid (consistent directional
pattern at all frequencies)
Uses:
CCM 21: often preferred for use as a
spot microphone, or as the main
pair for overall stereo pickup
CCM 21H: often preferred for use
when recording vocals, acoustic
guitar or percussion

CCM 21
CCM 22
– “Open Cardioid”
– optimal combination of classic car-
dioid directionality (CCM 4) with
the sonic character of the wide car-
dioid (CCM 21)
– directional pattern largely constant
throughout the frequency range
Uses:
for spot miking and as a soloist’s
microphone
