Dpa 4018c

DPA 4018C

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 4018 Supercardioid Microphone offers superb flexibility through modular accessories.
This microphone is part of our flexible pencil mic 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.

Features:

• Low noise and high sensitivity
• Highly directional for high isolation
• Most controlled supercardioid shape
• Uniform, frequency independent directionality
• Modular flexibility
