Directivity
Omni
Equal sensitivity to all direction, so that the microphone
doesn’t need to pointing toward the sound source. Low
handling and wind noise. Welcome by news gathering,
and music recording applications.
Cardioid
Picks up most signal on axis. Rejects side and picks up
least to the back. Suitable for live sound re-inforcement.
Apparent proximity effect and most singer likes to take
this bass boost advantages which is not good for speech.
Super Cardioid
Narrower than cardioid pattern. Suitable for multiple
microphone setup. Least sensitive angle pointing toward
side to rear where most stage monitors are located.
Same proximity effect as cardioid microphone.
Figure 8, bi-directional
Equal sensitive to both ends, and rejects the sides. Good
to noisy environment to reject distant noise and low
frequency. Also a good choice for stereo recordings, such
as Blumlein. Typical pressure gradient characteristic.
Shotgun
Based on interference tube theory, to achieve highest
axial signal pick-up and rejects off-axis sound as much
as possible. Due to poor wind noise rejection, suitable
wind screen shall be used at outdoor.
Select or set the directivity of your microphone for stereo recording, for various music instru-
ment, vocal, speech, and environmental sound pick-up. Pair of spaced omni for A/B stereo,
pair of near coincident cardioid for ORTF, and pair of coincident figure-8 at 90° setting for
Blumlein stereo.
CMH8CH polar variation
Double diaphragm structure with cardioid acoustic nature,
CMH8CH can be set at OMNI, Cardioid, and Figure-8
polar mode.
