ositioning the microphone
Position
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
loudspeakers 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. 135°; see polar diagram).
