In contrast, directional super cardioid mics are specifically designed to accept
mostly signal coming from directly in front, and to reject signal coming from
behind or from the side. The super cardioid pattern is utilized by the Q7 (as
shown in the illustration below). For this reason, the Q7 excels in environments
where there is a good deal of unwanted ambient sound—it delivers those signals
originating directly in front of the mic capsule itself while rejecting those that origi-
nate from behind.
The polar pattern also determines how prone a particular mic is to inducing feed-
back. Feedback is that characteristic nasty howling sound that occurs when a mic
is placed too close to a loudspeaker—the signal from the loudspeaker is fed into
the mic, then into the loudspeaker, then into the mic, over and over again until an
oscillating tone is generated. Because the super cardioid pattern utilized by the
Q7 is so good at rejecting signal not coming from directly in front of the mic,
you’ll find that use of the Q7 greatly minimizes feedback problems.
