The Shure Beta 98AMP is a precision-engineered miniature cardioid condenser microphone for professional sound reinforcement and studio recording. Features an integrated XLR preamplifier with a flexible gooseneck and the A75M Universal Microphone Mount for accurate placement in any configuration of toms, snares, or percussion. An extremely uniform cardioid polar pattern provides excellent gain-before-feedback, off-axis rejection of unwanted noise, and high maximum sound pressure level (SPL).
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
Ships with A75M Universal Microphone mount with quick release, for versatile and secure instrument and/or stand mounting
Furnished with snap-fit windscreen and zipper pouch

[1] 1 Pa=94 dB SPL
[2] THD of microphone preamplifier when applied input signal level is equivalent to cartridge output at specified SPL
[3] S/N ratio is the difference between 94 dB SPL and equivalent SPL of self noise, A-weighted
[4] All specifications measured with a 48 Vdc phantom power supply. The microphone operates at lower voltages, but with slightly decreased headroom and sensitivity.
