Shure Beta 98AD/C Miniature Cardioid Mic with A98D

• Uniform cardioid polar pattern provides maximum gain-before-feedback and rejection of off-axis sound for smooth high-end response and control
• Frequency response tailored for drums and percussion applications with a wide dynamic range for use in high SPL environments
• Precision-engineered design for unobtrusive microphone footprint
• Beta 98A models ship with external in-line preamplifier for discrete cable placement, snap-fit windscreen, and zipper pouch
• Beta 98AD/C ships with A98D drum mount featuring a flexible gooseneck for precise placement and secure attachment
• Beta 98A/C ships with RK282 shock mount swivel adapter for attachment to any standard microphone stand
