Shure Beta 91 Kick Drum Microphone With PreAam RPM626

The Shure BETA 91 is a high performance condenser microphone with a tailored frequency response designed specifically for kick drums and other instruments. It provides superb attack and punch, and delivers studio quality sound, with minimal distortion even at extremely high sound pressure levels.

The BETA 91 features a half-cardioid pattern (cardioid in the hemisphere above the mounting surface) throughout its frequency range to insure high gain before feedback and excellent rejection of unwanted sound.

Shure Beta 91 Features:

• Frequency response shaped specifically for kick drums and other instruments
• Wide dynamic range for use in high SPL environments
• Low-profile design requires no external mounting hardware
• Detachable cable for easy storage
• Legendary Shure quality, ruggedness, and reliability
