Audio-technica BP4073 Line + Gradient Condenser Microphone
The Audio-Technica BP4073 is a shotgun condenser microphone that adds virtually no heft to the end of your fish pole boom or to the top of a minicam. The BP4073 mic's overall length is just 9.17" and it weighs just 3.5 oz. Through the use of an innovative Audio-Technica design, the interference tube of the BP4073 microphone provides a narrow acceptance angle, effective for long-distance pickup. This highly directional mic offers low self-noise and is fully RoHS-compliant—free from all substances specified in the EU directive on the reduction of hazardous substances (RoHS). Requires 48V DC phantom power.
