DPA MICROPHONES 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 only 6.4cm, the 4018C has a highly directional super-cardioid 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 a spot or hanging mic for orchestra recording situations.
