Applications:
The PC Boundary is acoustically designed for high-quality sound reinforcement and broadcast applications. The frequency
response is tailored for wide-range sound reproduction with very natural sound pick-up. The PC Boundary microphone’s three
directional polar patterns allow the user to pick the directional polar pattern for optimum effect. For those applications where
gain-before-feedback is not a problem, an omnidirectional pattern is included. The PC Boundary microphone is ideal for
boardrooms, conference tables, or anywhere a high quality low profile microphone is required.
