View our rental Terms & Conditions

 Boundary microphones are typically a low profile microphone placed on a flat surface such as a table, floor, or wall. It's cardioid pickup pattern favors sound coming from directly in front of the microphone. This pattern also has the benefit of being less sensitive to sound coming from behind the microphone element. Boundary microphones are often used in boardrooms, theater applications and sporting events.
