The DPA 4017B Shotgun Pencil Microphone utilises a modified 4011 cardioid capsule within an interference tube design offering a low noise hyper-cardioid polar pattern. It is very light weight (2.4ozs/68gms) and is ideal for multi tasking, including ENG, fixed sports applications and of course main boom miking.
For greater control the microphone is fitted with a 50Hz high pass filter which can be increased to 120Hz accessed via a ring switch on the barrel of the microphone. A second switch gives a 4dB presence boost at 8Khz. In the design particular attention has been paid to ensuring a smooth off-axis response as well as maintaining the usual DPA sonic linearity on-axis. Capable of handling SPLs up to 152dB, immunity to RF emissions and fitted with adjustable filters, the 4017B is a very versatile super-directional broadcast/film microphone.
The 4017B capsule can be interfaced with any of the series pre-amps – The C pre-amp, for example, will reduce the length of the mic, but does not include the filters.
