Product Overview
The Shure RPW118 is a genuine OEM replacement cartridge, housing assembly, and matte grille for Shure wireless handheld transmitters equipped with the Beta 58A supercardioid dynamic capsule. It is the standard service replacement for Beta 58A wireless capsule damage across commercial wireless microphone systems, restoring the high-output dynamic performance that makes the Beta 58A a live sound and corporate AV standard. Compatible with Shure ULXD, QLXD, SLXD, and Axient Digital handheld transmitters.
Product Description
The Beta 58A is a supercardioid dynamic capsule widely specified in touring and commercial AV applications for its high SPL handling, strong off-axis rejection, and consistent output level with wireless transmitters. When an RPW118 capsule sustains physical or acoustic damage, the RPW118 replacement provides a factory-matched unit including the capsule, housing assembly, and matte grille. This keeps Beta 58A wireless transmitters in service without the cost of transmitter replacement. AV integrators specifying Shure wireless systems in conference rooms, training rooms, or multi-purpose spaces benefit from stocking the RPW118 as a standard spare. Limit of one per order applies.
