Микрофон DPA 4017B Shotgun
Описание
SHOTGUN MICROPHONE
At just 210 mm (8.3 in) and 68 g (2.4 oz), this mic is one of the shortest and lightest shotgun condenser microphones available. At the same time, it offers impressive accuracy, clarity and musicality.The mic is fully immune to RF emission and the 19 mm (0.75 in) condenser cartridge is capable of handling peak SPLs of 152 dB before clipping. Designed for a broad range of applications, the d:dicate™ Microphones Series is ideal for use with camera systems, in fixed positions at sports facilities, for broadcast/ENG/film booming and even studio recording environments.
The microphone capsule
The 4017B Shotgun Microphone is equipped with a highly-directional hypercardioid pickup pattern; obtained using a supercardioid design with an interference tube that provides excellent off-axis rejection. Its unique directional pattern is useful when you need exceptionally high directivity with high background noise rejection. It is convenient when you cannot place the mic close enough to the sound source. The MMP-B preamplifier is best if you want easily accessible high boost and low cut switches.Extensive research and development has been undertaken to optimize the sound coming from the sides and back of the microphone. One of the key accomplishments is that we have minimized often very un-linear response of a shotgun microphone due to its side lobes. 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.The d:dicate™ 4017B Shotgun Microphone features two onboard filters. They are activated via an ingenious switching ring design. With a simple twist of two sturdy rings, engineers can implement a high-frequency boost that adds a 4 dB shelf at 8 kHz. This compensates for hi loss when used with windjammers. A first-order bass roll-off below 120 Hz minimizes 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.The d:dicate™ 4017B Shotgun Microphone is also available with Rycote Windshield and suspension system – a fully-packed and ready-to-go solution.

За производителя
DPA Microphones е компания от Дания, производител на професионални микрофони. Всичко започва през далечната 1950 година, когато предшествениците на DPA Microphones, Brüel & Kjær разрабоват първите толкова прецизни и точни микрофони. Прецизен звук, безкомпромистна последователност и изключителна надеждност, вече повече от шест десетилетия DPA Microphones пишат своята история в музикалния бизнес и не само, микрофони на компанията се ползват в CNN и Формула 1. Всички продукти на DPA Microphones се изработват и тестват ръчно във фабриката им в Alleroed, Дания.
