The AT4073a features a broad band, linear on axis frequency response, with maximum rejection of sounds from both the sides and the rear of the microphone. Rear polar lobing, common in shotgun microphones, has been greatly reduced and the off axis response remains highly uniform. The resultant lack of sound coloration on and off axis makes the AT4073a particularly useful for miking dynamic action in film/TV audio as well as in "spot" miking techniques in the music studio or theater.
