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.
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 98A models ship with external in-line preamplifier for discrete cable placement, snap-fit windscreen, and zipper pouch
