SHURE BETA 98S Supercardioid Instrument Microphone for Live Performance and Studio  The Shure Beta 98/S is a compact, high-output supercardioid condenser microphone for professional sound reinforcement and studio recording. Its extremely uniform supercardioid pickup pattern provides high gain-before-feedback and excellent rejection of unwanted noise. Its high maximum sound pressure level (SPL) makes it useful for a variety of instruments including drums, piano, reed, wind, and string. The Beta 98/S can also be used for amplified guitars.

The optional A98D drum mount has a specially designed gooseneck that allows the microphone to be positioned freely, yet holds it securely in place once the ideal placement has been found.

• Tailored frequency response for studio quality performance
• Wide dynamic range for use in high SPL environments
• Uniform supercardioid pattern for high gain before feedback and superior rejection of off-axis sound
• Optional A98D drum mount is unobtrusive and versatile, allowing precise positioning of the microphone while holding it firmly in place
• Compact design reduces stage clutter
• Detachable cable for easy storage
• Interchangeable microphone cartridges with different polar patterns are available
• Legendary Shure quality, ruggedness, and reliability
