Shure BETA 91A Kick Drum Microphone

 

\nThe Shure Beta 91A is a boundary microphone that can double as a kick drum mic, as it can capture the punch and attack of low-frequency instruments such as kick (bass) drums. It features a wide frequency response well suited for capturing a variety of audio signals such as organ and piano. The flat, boundary design also aides in producing a strong, solid low-end response, as well as make it easy to mount inside of a bass drum. The Beta 91A is ideal for both recording and sound reinforcement alike.\n\n

\n
• Wide Frequency Response
\n
• Cardioid Polar Pattern
\n
• Interchangeable Cartridge
\n
• Uniform half-cardioid polar pattern for maximum gain-before-feedback and rejection of off-axis sound
\n
• Low-profile design features integrated preamplifier and XLR connector to facilitate setup efficiency while minimizing stage clutter
\n
• Frequency response tailored for kick drum/low frequency applications with a wide dynamic range for use in high SPL environments
\n
• Two-position contour switch to maximize attack and clarity depending on application: select the flat response setting for natural sound in most applications or the Low-Mid Scoop setting for a strong low frequency punch with plenty of higher frequency attack
