Shure BETA 98AMP/C Cardioid Instrument Microphone

Instrumental microphone combines an integrated preamplifier with a miniature condenser capsule to provide a smooth response for percussion. It features a flexible gooseneck and the A75M microphone mount for secure placement in many configurations.

• Uniform cardioid polar pattern provides maximum gain-before-feedback and rejection of off-axis sound for smooth high-end response and control
• Precision-engineered design features integrated preamplifier and XLR connector to maximize setup efficiency while minimizing stage clutter
• Frequency response tailored for drums and percussion applications with a wide dynamic range for use in high SPL environments
• Flexible gooseneck for precise placement and easy adjustment
• A75M Universal Microphone mount with quick release, for versatile and secure instrument and/or stand mounting
