Positioning the microphone
If sibilance or “popping” occurs, position the microphone
not directly in front of the mouth but slightly to the side.
In order to prevent feedback, position monitor loud-
speakers so that they are located in the angle area of the
highest cancellation of the microphone.
In order to prevent interference due to crosstalk between
adjacent sound sources, try to position the microphone
so that the interfering sound source is located in the
angle area of the highest cancellation of the microphone
(approx. 150°; see polar diagram).
