BETA 98AMP Miniature Cardioid Drum Microphone

Model# SU-BETA 98AMP/C

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).

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