Audio-Technica BP4073 Line + Gradient Condenser Microphone Product Description
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).
