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.
