3-Pack BETA 98AMP/C Miniature Drum Microphone

Model# SU-BETA 98AMP/C-3PK

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).
