20Hz-20kHz HWith an overall length of just 233mm and weight of just 99g, this microphone adds virtually no heft to the end of a fish pole or the top of a minicam. Through the use of an innovative Audio-Technica design, the interference tube of the BP4073 provides a narrow acceptance angle, effective for long-distance pickup. The highly directional mics offer low self-noise and are fully RoHS-compliant â free from all substances specified in the EU directive on the reduction of hazardous substances (RoHS).
Designed for use in broadcasting, film/TV production and theater sound reinforcement applications
Direct-coupled, balanced output ensures a clean signal even in high-output conditions
Innovative acoustic design provides same directivity as mics up to 50% longer
