Toroid Pattern Applications
The toroid pattern rejects sound from directly above the microphone to reduce noise from video projectors or other sources of
unwanted sound. It is the simplest way to ensure equal coverage among all talkers, while retaining the benefits of the rejection
provided by a directional polar pattern. When this pattern is used, the audio is sent over a single channel. Therefore, when au-
tomatic mixing is desired, configure the microphone to use multiple directional patterns instead of the toroid pattern.
Noise from a ceiling-mounted projector is rejected, while all talkers are covered.
