Shure RPM626 In-Line Preamplifier for WBH53, Beta 53/91/98 & MC50B/51B

Enhanced Audio Clarity with RFI Resistance

The Shure RPM626 In-Line Preamplifier is designed to boost the performance of specific Shure microphones, including the WBH53, Beta 53, Beta 91, Beta 98, MC50B, and MC51B, by providing clean, reliable audio with enhanced resistance to Radio Frequency Interference (RFI). Ideal for professional audio applications across Australia, such as live performances, theater, and broadcast, this compact preamplifier ensures optimal signal quality in RF-heavy environments. It converts 11–52V phantom power to the voltage required for these microphones’ electret condenser circuitry.

Optimized for Shure Microphones

The RPM626 preamplifier delivers low-noise amplification tailored for Shure’s high-performance microphones, ensuring clear, undistorted audio output. It features a TA4M input connector compatible with the specified microphones and a standard 3-pin XLR output for seamless integration with professional mixers and audio interfaces. By enhancing RFI resistance, it mitigates interference from nearby transmitters, two-way radios, or grounding issues, making it a critical component for reliable audio in challenging environments. The preamplifier requires an external 11–52V DC phantom power source, as it does not independently power the microphone.

Compact and Durable Design

Crafted with Shure’s renowned durability, the RPM626 features a compact, lightweight black housing that integrates seamlessly into professional setups without adding bulk. Its robust construction ensures reliability for both portable and permanent installations, such as in theaters, conference venues, or broadcast studios. The fixed-gain design eliminates the need for user adjustments, providing consistent performance optimized for the specified Shure microphone models.
