Shure RPW118 Beta 58A Replacement Capsule for Shure Wireless Transmitters

The Shure RPW118 is a Beta 58A replacement capsule cartridge for Shure wireless handheld transmitters — the screw-on dynamic supercardioid head that gives wireless mic users the same legendary sound as the wired Beta 58A. This is NOT a complete microphone; it's the capsule element that mates with a compatible Shure wireless transmitter body.

What it does: Screws onto compatible Shure wireless handheld transmitter bodies to give them Beta 58A vocal sound — the slightly brighter, more articulate cousin of the SM58 with tighter supercardioid pattern for higher gain before feedback. Lets engineers configure wireless mics with exactly the capsule they want for the artist.

Compatibility: Designed for Shure wireless transmitter bodies including QLX-D, ULX-D, SLX-D, BLX, GLX-D handheld transmitters, and Axient Digital handhelds. Verify your specific transmitter body before purchase — not all Shure wireless systems use interchangeable capsules.

Specifications:

• Beta 58A supercardioid dynamic capsule element
• Tighter supercardioid pattern than SM58 (more gain before feedback)
• Bright, articulate vocal sound — cuts through dense mixes
• Neodymium magnet for high output and consistent sensitivity
• Hardened steel mesh grille

Stock for: AV rental companies refreshing wireless inventory, live sound engineers swapping capsule types for different artists, churches and venues replacing damaged wireless heads, and Shure dealers as a service part.
