FIGURE 1. KSM44 Front and Back
Cardioid. Picks up sounds directly in front of the microphone and is least
sensitive to those in back. Cardioid is the most commonly used pattern in studio
recording and live-sound applications. See Figure 4.
Omnidirectional. Picks up sound equally from all directions. This pattern
is best for picking up room ambience and miking several sources at once, such as
singers or an ensemble. Omnidirectional patterns do not exhibit proximity effect.
See Figure 6.
Bidirectional. Picks up equally from the front and back of the microphone
while rejecting sounds from the sides. Bidirectional is often used in microphone
configurations for stereo recording (such as mid-side and Blumlein techniques).
See Figure 8. Note: As with all bidirectional microphones, sounds picked up from
the front will be in polarity with the source and those picked up from the back will
be out of polarity with the source.
