The DPA 2017 Shotgun Microphone is an extremely directional boom mic that combines crystal clear, authentic sound and stable, consistent performance, even under harsh conditions. What makes the 2017 special is that its acoustical performance sets it apart from other microphone designs. DPA crafted it to have efficient off-axis rejection combined with an off-axis frequency response that is much more linear than most similar shotgun mics. The 2017 shotgun mic performs consistently in a variety of conditions, like cold weather and humid environments as well as in generally harsh situations. Although the interference tube surrounding the capsule is quite long, the entire mic is contained in a shorter, lighter mic housing than many other mics. This makes the DPA 2017 shotgun mic a practical choice in a wide range of applications. DPA's 2017 microphone is designed to ensure that the sound from the primary sound source combines effortlessly with natural sound captured off-axis. The sound is clear and lifelike, including the heavily-attenuated off-axis input. It exhibits the same non-coloration of the off-axis response, i.e., it sounds like what is coming in on-axis, just damped accordingly with the side and rear entries. DPA 2017 Shotgun Mic Features Accurate, clean sound from the primary sound source combines effortlessly with natural sound captured off-axis Extraordinary durability, with reinforced construction to perform in challenging environments, including high humidity Outstanding off-axis rejection for optimal isolation of the desired sound source Extremely directional pick-up pattern, with an effective interference tube in a compact housing Easy to set up, position and use in fixed positions, on booms and on camera systems Low self-noise, for excellent performance in quiet environments or with many open microphones DPA 2017 Specifications Directional pattern Supercardioid at 1 kHz Principle of operation Pressure gradient Cartridge type Pre-polarized condenser Frequency response 20 Hz - 20 kHz Effective frequency range, ±2 dB, at 60 cm (23.6 in) 70 Hz to 18 kHz with typ. 2 dB soft boost at 15 kHz Sensitivity, nominal, ±2 dB at 1 kHz 25 mV/Pa (± 2 dB ) Equivalent noise level, A-weighted Typ. 13 dB(A) re. 20 µPa (max. 15 dB(A)) Distortion, THD < 1% 140 dB SPL (143 dB SPL peak) Dynamic range Typ. 130 dB Max.
