• Excellent RF
Immunity
• Lightweight
• Uniform off-axis response
• Highly directional
Equipped with a highly directional supercardioid pickup pattern,
obtained using a supercardioid design with an interference tube
that provides excellent off-axis rejection, 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. 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.
Tune out the surroundings
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.
Small size, big performance
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.
Screwdriver-free filter access
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
