Shure Beta 98AMP/C Miniature Cardioid Condenser Drum Microphone

Miniature Cardioid Condenser Microphone with XLR Preamp and A75M Universal Stand Adapter

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 98AD/C includes A98D drum mount with flexible gooseneck that makes it an essential, accurate choice for toms, snares, and percussion. Beta 98A/C is recommended for a variety of acoustic or amplified instruments including drums, piano, reed, wind, and strings.

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 98A models ship with external in-line preamplifier for discrete cable placement, snap-fit windscreen, and zipper pouch
• Beta 98AD/C ships with A98D drum mount featuring a flexible gooseneck for precise placement and secure attachment
• Beta 98A/C ships with RK282 shock mount swivel adapter for attachment to any standard microphone stand
