Overview

Combines superior attack and punch for studio-quality sound.

The Shure BETA 91A is designed for use with kick drums as well as other traditional low-frequency applications, including piano. Featuring an updated microphone capsule, integrated preamplifier and XLR connection, BETA 91A offers a strong low-frequency response and is specifically tailored for bass frequency applications. The BETA 91A combines superior attack and punch for studio-quality sound, even at extremely high sound pressure levels (SPL).

A 2-position contour switch maximizes 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. The BETA 91A requires phantom power and comes with a zippered pouch.

Features

  • Uniform half-cardioid polar pattern for maximum gain-before-feedback and rejection of off-axis sound
  • Precision-engineered low-profile design features integrated preamplifier and XLR connector to maximize setup efficiency while minimizing stage clutter
  • Frequency response tailored for kick drum/low frequency applications
  • Wide dynamic range for use in high SPL environments
  • Two-position contour switch to maximize attack and clarity
  • Requires no external mounting or accessories for ease of use and storage
  • Furnished with zipper pouch
