DPA 4018A

This mic is part of the flexible d:dicate Microphones Series. It has a highly-directional supercardioid pickup pattern with a smooth and uniform off-axis frequency response.

The d:dicate 4018A Supercardioid Microphone is designed for a broad range of music recording and broadcast/ENG/film long-distance miking applications. It can be used for booming, dialogue, interview and table or spot-recording use. The mic also offers superb expandability through modular accessories. It is ideal for use as spot or hanging mic for orchestra recording situations. The microphone capsule The supercardioid shape is frequency independent, securing an identical sound color around the microphone. The usual rear lobe heard on most supercardioids is minimized on this capsule. This makes it much more isolated without sudden frequency dependent peaks and dips. A truly flexible range This mic is part of the flexible d:dicate™ Microphone Series. At any time, and with no tools needed, it is possible to transform the d:dicate™ 4018A Supercardioid Microphone into a new configuration. You can combine it with another d:dicate™ or d:facto™ Microphone Capsule or Preamplifier.
