- DESCRIPTION
- SPECIFICATIONS
Kick drum microphone provides a strong low-end response and maximum gain-before-feedback due to its half-cardioid polar pattern. It features a two-position contour switch to maximize attack and clarity and a low-profile design.
-
Cartridge Type: Electret Condenser
-
Polar Pattern: Half-cardioid (cardioid in hemisphere above mounting surface)
-
Frequency Response: 20 to 20,000 Hz
-
Output Impedance @ 1 kHz: 146 Ω
