The Shure RPW122 is a specialized condenser replacement cartridge designed specifically for the Shure Beta 87C supercardioid handheld wireless microphone transmitter. This OEM part is engineered to restore the transmitter to its original sonic and mechanical specifications, ensuring the return of the Beta 87C's distinctive vocal character. The Beta 87C capsule is known for its tight supercardioid pattern, providing exceptional gain before feedback and outstanding rejection of off-axis sound, coupled with a bright, detailed frequency response that emphasizes vocal presence. The RPW122 cartridge contains the complete condenser element and is the definitive solution for repairing a transmitter with a damaged or degraded capsule.

Installation of the RPW122 involves meticulous disassembly of the transmitter's grille and the soldering of the new cartridge's connections, a task that requires technical skill and should be undertaken by a qualified professional. The cartridge is manufactured to the same exacting standards as the original, featuring robust construction and internal shock mounting to preserve the microphone's ability to handle high sound pressure levels while minimizing handling noise. For vocalists and engineers who depend on the Beta 87C's articulate, feedback-resistant performance, the RPW122 is a vital spare part that safeguards the longevity and performance of their wireless investment.

Keeping an RPW122 in reserve is a prudent measure for maintenance teams in touring, broadcast, and rental operations. It directly addresses failures caused by physical impact, moisture ingress, or general aging of the acoustic component. By facilitating an exact acoustic restoration, this replacement cartridge ensures that the wireless system continues to deliver the precise, clear, and powerful vocal reproduction that is critical for professional live and broadcast applications.
