Brand: Shure
The Shure M91 ED-BJ is a high-quality microphone capsule designed for use with select Shure microphone models, including the SM91 and BETA 91A. It features an electret (ED) design, which eliminates the need for a battery to provide polarization voltage. The "-BJ" designation indicates that the capsule has been specially modified to have a lower sensitivity, making it suitable for use in high-sound-pressure applications, such as loud stage monitors and other voluminous sound sources. The M91 ED-BJ offers exceptional sensitivity, frequency response, and low noise, making it a reliable choice for demanding audio applications.
