Shure RPW122 – Wireless Beta 87C Replacement Cartridge Assembly

Product Overview

The Shure RPW122 is a genuine OEM replacement cartridge, housing assembly, and matte grille for Shure wireless handheld transmitters equipped with the Beta 87C cardioid condenser capsule. It restores the wider cardioid polar response and condenser vocal performance of the Beta 87C to a damaged wireless transmitter, and is compatible with Shure ULXD, QLXD, SLXD, and Axient Digital handheld transmitters that accept interchangeable capsules. The RPW122 is essential maintenance stock for commercial AV environments where Beta 87C wireless mics are deployed.

Product Description

The Beta 87C uses a cardioid polar pattern rather than the supercardioid pattern of the Beta 87A, making it a preferred choice for presentations and vocal applications where a wider pickup angle and more natural off-axis response is beneficial. When an RPW122 capsule sustains damage, the RPW122 assembly replaces the capsule, housing, and matte grille as a single matched unit. This preserves the cardioid condenser sound signature that was specified for the installation and avoids the cost of transmitter replacement. AV integrators and facilities managers maintaining Shure wireless infrastructure in boardrooms, conference rooms, or multi-purpose rooms benefit from stocking the RPW122 as a standard service component. Limit of one per order applies.

Frequently Asked Questions

What is the difference between the RPW122 (Beta 87C) and RPW120 (Beta 87A)?
The Beta 87C uses a cardioid polar pattern while the Beta 87A is supercardioid. The cardioid pattern of the Beta 87C has a wider pickup angle and more gradual off-axis rolloff, making it more forgiving of variable mic positioning. The Beta 87A's supercardioid pattern provides stronger rear rejection and is preferred when feedback control is critical. Choose the RPW122 when maintaining existing Beta 87C installations.

Which Shure wireless transmitters are compatible with the RPW122?
The RPW122 is compatible with Shure handheld transmitters in the ULXD, QLXD, SLXD, and Axient Digital families that use an interchangeable capsule design. Confirm your specific transmitter model against Shure's compatibility documentation before ordering.

Does the RPW122 include the grille?
Yes. The RPW122 ships as a complete assembly including the Beta 87C capsule, housing, and matte grille.

What warranty coverage applies to the RPW122?
Shure covers the RPW122 under its standard product warranty. Contact Creation Networks or Shure directly for current warranty terms applicable to your installation.
