The DPA 4017B is a short and exceptionally lightweight shotgun microphone that truly measures up to DPA’s impressive reputation for accuracy, clarity, and musicality. 

Equipped with a highly directional supercardioid pickup pattern, obtained using a supercardioid design with an interference tube that provides excellent off-axis rejection. Designed for a broad range of applications, the phantom powered 4017B is ideal for use with camera systems, in fixed positions at sports facilities, for broadcast/ENG/film booming, and even studio recording environments.
 
Extensive research and development has been undertaken to optimize the sound coming from the sides and behind the microphone. Minimizing the often very un-linear response of a shotgun microphone due to its side lobes is one of the key accomplishments of the 4017B. The condenser capsule uses a high voltage pre-polarized back plate, endowing the shotgun with high output as well as wide dynamics, extremely low noise and distortion specifications.
 
At just 210 mm (8.3 in) in length and 68 g (2.4 oz) in weight, the aluminum-bodied DPA 4017B is among the smallest and lightest boom microphones available. But that’s not to say that it’s small on performance. Fully immune to RF emission, the 4017B’s 19 mm (0.75 in) condenser cartridge is capable of handling peak SPLs of 152 dB before clipping.
 
The 4017B features two onboard filters that are activated via an ingenious switching ring design. With the simple twist of two sturdy rings, engineers can implement a high-frequency boost that adds a 4 dB shelf at 8 kHz and a first-order bass roll-off below 120 Hz to minimize handling and wind noise. A permanent third-order high-pass filter at 50 Hz effectively removes unwanted low frequency disturbance from handling and wind noise.
