Description
d:dicate 4018C compact supercardioid microphone.
- Highly directional compact supercardioid
- Uniform directionality
- Low noise and high sensitivity for distant positioning
- Very sleek and compact boom, table or spot mic
The 4018C is a compact supercardioid booming microphone and is part of the modular DPA d:dicate recording microphones series.
At the length of only 6.4cm, the 4018C 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 the 4018C making it much more isolated without sudden frequency dependent peaks and dips.
Designed for a broad range of broadcast/ENG/film long-distance miking applications, such as booming, dialogue, interview and table or podium use, the 4018C offers superbly flexibility through modular accessories. The 4018C is also ideal for use as spot or hanging mic for orchestra recording situations.
