Overview

AT4073a

The AT4073a has been discontinued. The BP4073 is a similar model, click here for more information. The AT4073a sets new standards in small size and light weight. With an overall length of just 9.13” 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.
