Shure RPW122 — Wireless Beta 87C Replacement Cartridge
RPW122 Overview
The Shure RPW122 is a factory-spec replacement cartridge assembly designed specifically for wireless Beta 87C microphone systems. It replaces the cartridge, housing assembly, and matte grille as a complete unit, ensuring your wireless vocal microphone returns to original Beta 87C performance standards. This is the correct OEM solution for touring companies, houses of worship, and production facilities that need to restore a damaged or worn Beta 87C capsule without replacing the entire transmitter. Sourcing a genuine Shure replacement eliminates the risk of off-spec substitutions that can compromise polar pattern integrity and frequency response.
The RPW122 installs directly onto compatible wireless Beta 87C transmitters, making it a straightforward field or shop replacement that minimizes downtime in active inventory.
