With its first-class design and perfect performance, the BW-30 wired boundary microphone has become the best choice for speech and language reinforcement in studios, courtrooms, classrooms and conference rooms. A unidirectional sensor is built in to reduce environmental noise interference. The best conditions for use are on a solid, smooth surface that reflects sound. Due to the built-in ultra-low noise amplifier, the microphone can pick up and restore clear, natural sound.
