Shure BETA 98AMP/C Cardioid Condenser Instrument Microphone

The Shure Beta 98A is a precision-engineered compact, high-output miniature condenser microphone for professional sound reinforcement and studio recording. An extremely uniform cardioid polar pattern provides excellent gain-before-feedback and off-axis rejection of unwanted noise.

Both Beta 98A configurations feature high sound pressure level capability (SPL). Beta 98AMP/C includes an integrated XLR preamplifier and A75M universal microphone mount.

Features

• 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 98AD/C ships with A75M Universal Microphone Mount
