The Shure Beta 91A-X is a versatile boundary microphone designed to excel in capturing the punch and attack of low-frequency instruments, including kick (bass) drums. It features a wide frequency response, making it ideal for a range of audio signals.

Features:

Wide Frequency Response: Ideal for capturing a variety of audio signals with excellent clarity and detail.
Low-Profile Design: Facilitates easy mounting inside of a bass drum and minimizes stage clutter.
Cardioid Polar Pattern: Provides effective rejection of off-axis sound for focused audio capture.
Interchangeable Cartridge: Allows for flexible use and customization based on different recording needs.

Type: Electret Condenser
Frequency Response: 20 to 20,000 Hz
Polar Pattern: Half-cardioid (cardioid in hemisphere above mounting surface)
Impedance: 146 Ohms
