The Shure RPW120 Wireless Beta 87A Replacement Cartridge is a genuine Shure condenser microphone head assembly designed for compatible Shure handheld wireless transmitters. Featuring the renowned Beta 87A supercardioid microphone design, the RPW120 provides detailed vocal reproduction, focused directional pickup, and professional performance for live sound applications.
The replacement assembly includes the Beta 87A microphone cartridge, housing, and grille, allowing users to replace a damaged wireless microphone head or configure a compatible Shure handheld transmitter with Beta 87A vocal pickup characteristics.
Beta 87A Condenser Vocal Performance
The RPW120 incorporates the Beta 87A condenser microphone design, known for its detailed vocal response and strong presence in professional sound reinforcement applications.
Its tailored frequency response helps reproduce vocals with clarity and definition, making it suitable for lead singers, background vocalists, worship leaders, presenters, and professional performers.
The Beta 87A design is particularly useful when vocal detail and consistent microphone technique are priorities.
Supercardioid Pickup for Directional Control
The RPW120 features the Beta 87A's supercardioid polar pattern.
This directional design emphasizes sound arriving from the front of the microphone while reducing pickup from the sides.
The focused pickup pattern can help improve separation between the vocalist and surrounding instruments, stage monitors, and other sound sources.
Supercardioid microphones have a small rear pickup lobe, so appropriate loudspeaker and monitor placement remains important for feedback control.
Complete Wireless Microphone Head Assembly
Unlike a loose internal microphone capsule, the Shure RPW120 is a complete replacement microphone head assembly.
Shure specifies that it replaces the cartridge, housing assembly, and matte grille for compatible wireless Beta 87A applications.
This integrated design provides a practical replacement when the original wireless microphone head is damaged or when a compatible transmitter needs a different microphone capsule configuration.
The RPW120 does not include a handheld wireless transmitter, receiver, or complete wireless microphone system.
Compatible Shure Wireless Transmitters
The RPW120 uses Shure's interchangeable wireless microphone cartridge interface and is supported by various compatible Shure handheld transmitters.
Shure identifies the RPW120 as a Beta 87A cartridge option for the ULX-D wireless system, among other supported configurations.
Because wireless transmitter designs and product generations differ, customers should verify compatibility with their exact handheld transmitter before ordering.
The RPW120 is not the same replacement part as the R193 cartridge used inside wired Beta 87 and Beta 87A microphones.
Professional Live Sound Applications
The Shure Beta 87A microphone design is widely suited to professional vocal sound reinforcement.
The RPW120 is useful for touring sound systems, concert stages, houses of worship, corporate presentations, and wireless microphone installations requiring detailed condenser vocal reproduction.
Its replaceable head design also helps simplify equipment maintenance and allows compatible wireless systems to be adapted to different microphone preferences.
Replacement and Installation
The RPW120 is designed to attach to compatible Shure handheld wireless transmitters through the appropriate cartridge interface.
Installation procedures vary by transmitter model. Certain older transmitters use retaining screws or other model-specific hardware.
Follow the instructions supplied by Shure and avoid touching the electrical contact surfaces during replacement.
