Audio-Technica BP4073 9in Line Gradient Long Distance Pickup Microphone

The Audio-Technica BP4073 is a compact and lightweight line gradient microphone designed for exceptional performance in broadcasting, film/TV production, and theater sound reinforcement. At just 9.17 inches in length and weighing a mere 3.5 ounces, it adds virtually no heft to the end of a fish pole or the top of a mini camera. This microphone incorporates an innovative Audio-Technica design in its interference tube, providing a narrow acceptance angle that is highly effective for long-distance pickup.

This highly directional microphone boasts low self-noise and operates in compliance with the RoHS directive, meaning it is free from all substances specified in the EU directive on the reduction of hazardous substances. Whether you're capturing sound in challenging environments or need superior audio quality for professional applications, the BP4073 delivers reliable performance.
