The Shure RPW504 is a mounting accessory kit designed to securely house two compatible Shure half-rack width wireless receivers within a single, organized unit for standard 19-inch equipment rack installation. This kit provides a professional and space-efficient solution for audio technicians and system integrators who need to consolidate multiple receiver units, such as those from the QLX-D or SLX-D series, into a tidy, rack-mountable assembly. The primary components of the kit are two metal side brackets that clamp onto the receivers, effectively combining them into a single unit that occupies 1U (one rack unit) of vertical space. This method of mounting is far more secure and organized than simply stacking the individual receivers on a shelf, preventing shifting, vibration, and potential damage to connectors.

The installation process is straightforward: the brackets attach to the sides of the receivers using the included screws, and the resulting combined unit is then mounted into the equipment rack using standard rack screws through the integrated flanges. This creates a clean, integrated appearance and ensures that all front-panel controls and displays remain easily accessible. By mounting two receivers in 1U of space, the RPW504 effectively doubles the rack density compared to using individual full-rack-width shelves or trays, freeing up valuable rack space for other critical audio equipment like processors, amplifiers, or power conditioners.

For touring sound companies, fixed installation contractors, and rental houses, the RPW504 is an essential accessory for efficient and professional system builds. It enhances the reliability of the setup by securely fixing the receivers in place, simplifies cable management by creating a unified unit, and presents a clean, professional appearance. This kit exemplifies Shure's attention to the practical needs of system deployment, providing a simple, robust solution for managing the physical integration of their professional wireless gear.
