• 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 6,4 cm (2,5 in), 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. |
