Designed for a broad range of long-distance broadcast, ENG and film miking applications, such as booming, dialogue, interview and table or podium use, the d:dicate™ 4018 Supercardioid Microphone offers superb flexibility through modular accessories.
This microphone 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 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.
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.
- Low noise and high sensitivity
