Introduction; Technical Description - DPA 4017 User Manual

INTRODUCTION

The DPA 401 7 is a short and exceptionally lightweight shotgun microphone,
offering a very directional pickup pattern with the typical natural DPA clarity
maintained.
The 401 7 has been designed for a broad range of uses, from camera systems
to fixed positions at sports facilities and for booming in ENG, broadcast, and
film applications. Due to its remarkable clarity, wide dynamic range, and excellent
rejection characteristics, the 401 7 is equally at home in the recording studio and
when used for sound reinforcement/live music miking.
At just 2 10 mm (8. 3 inches) in length and 7 1 grams (2.5 ounces) in weight, the
401 7 is compact in size and among the lightest boom microphones available.
