Middle Atlantic RSH4S3R-MC – 3U McIntosh Custom Rackshelf, 15.5" Depth

Product Overview

The Middle Atlantic RSH4S3R-MC is a 3U custom rackshelf from the RSH-4S series with a faceplate cut for McIntosh components, letting you mount McIntosh audio equipment in a standard 19" rack or enclosure without modification. The shelf provides a 15.5" deep platform and a textured black powder coat finish. Three rack spaces of height accommodate the taller front panels typical of McIntosh gear. The component installs like conventional rackmount equipment, with no drilling or chassis alteration.

Product Description

McIntosh amplifiers, preamplifiers, and source components are built for shelf placement, not 19" racks, yet many high-end residential systems consolidate equipment into a Middle Atlantic enclosure. The RSH4S3R-MC bridges that gap: it is a custom rack shelf whose steel face carries a McIntosh-specific cut (the -MC designation), framing the component's front panel for a clean, integrated appearance in the rack. The 3-space height (5.25") suits the larger faceplates common across the McIntosh line, while the 15.5" (R) shelf depth supports substantial chassis while preserving rear clearance for interconnects and power cabling. Like the rest of the RSH-4S custom rackshelf family, the shelf is finished in textured black powder coat that matches Middle Atlantic racks, blank panels, and vent panels. Mounting is hardware-simple: the shelf fastens to standard EIA rack rails, and the component rests on a fully supported platform, so there is no drilling, bracket fabrication, or modification to the equipment itself. This makes the RSH4S3R-MC a sensible choice for listening rooms, media rooms, and whole-home audio head ends where McIntosh equipment shares a rack with AV processors and network gear. For standard component cuts in the same family, see the RSH4S2M 2U custom rackshelf.
