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.

• 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
