• Highly directional
Supercardioid
• Uniform, frequency independent directionality
• Low noise and high sensitivity for distant positioning
• Excellent for spot miking orchestra sections or singers
The 4018A is a highly directional, first-class supercardioid
microphone and is a part of the modular DPA d:dicate Recording
Microphones series.
With its remarkably well controlled supercardioid shape and uniform
off-axis frequency response, the 4018A offers high separation
without odd off-axis frequency peaks and dips. 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 4018A making it much more
isolated.
Designed for a broad range of music recording and
broadcast/ENG/film long-distance miking applications, such as
booming, dialogue, interview and table or spot-recording use, the
4018A also offers superb expandability through modular accessories.
The 4018A is ideal for use as spot or hanging mic for orchestra
recording situations. |
