BP4073 Line + Gradient Condenser Microphone
With an overall length of just 9.17” and weight of just 3.5 oz, 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 – 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
- Switchable 80 Hz hi-pass filter & 10 dB pad
- Rugged housing made of lightweight structural-grade aluminum alloy
- RoHS-compliant – free from all substances specified in the EU directive on the reduction of hazardous substances (RoHS)
