Electro-Voice PC Boundary manual Applications, Technical Specifications

Engineering Data Sheet

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.
