Shure RPM89/PRE Replacement XLR Preamplifier

Shure RPM89 XLR Microphone Preamplifier

The Shure RPM89 is a professional-grade XLR preamplifier designed to replace the preamp section of the VP89S, VP89M, and VP89L End-Address Shotgun Condenser Microphones. Built around a discrete Class A design, it delivers exceptionally clean audio with low self-noise, high output level, and fast transient response, ensuring accurate capture of both subtle detail and dynamic sound sources.

Engineered for broadcast, film, and professional audio applications, the RPM89 offers minimal harmonic and intermodulation distortion with no crossover distortion, resulting in natural and transparent sound reproduction. To help manage unwanted low-frequency noise and rumble, the preamplifier includes a selectable low-frequency roll-off, allowing users to choose between a flat response or a 200 Hz roll-off depending on recording conditions.

Constructed from rugged aluminum alloy with a lightweight form factor, the RPM89 is designed for reliability in demanding field and studio environments. Its compatibility with VP89 and SM89 microphone capsules makes it a flexible and dependable component within Shure’s modular shotgun microphone system.
