Audio-Technica BP 4071 Richtmikrofon

and weight of just 4.0 oz, the mic adds virtually no heft to the end of a fish pole or the top of a minicam. Through the use of an advanced, propriety Audio-Technica design, the interference tube of the AT4073a provides a narrow acceptance angle that would require a tube 50 percent longer using conventional technology. Audio-Technica has pioneered a unique interference tube design* in the AT4071a and AT4073a shotgun mics that provides the same directivity as mics up to 50 percent longer.

Designed for critical long-distance pickup in broadcasting, film/TV production and theater sound reinforcement applications

Direct-coupled, balanced output ensures a clean signal even in high-output conditions

Exclusive acoustic design* provides same directivity as mics up to 50% longer

Switchable 150 Hz hi-pass filter

Rugged housing made of lightweight structural-grade aluminum alloy
