Sennheiser 507351 Pro Audio Wireless Microphone System

The Sennheiser 507351 is a rack-mount adapter kit engineered for the XSW series of wireless audio components. Rather than leaving stationary transmitters and receivers sitting loose on a shelf or table, this kit lets audio technicians and venue installers secure up to two XSW units side by side in a standard 19-inch equipment rack. The package includes rackmount ears, a connecting plate, a rack mount front panel, mounting screws, and cover caps, providing everything needed for a tidy and professional installation without hunting down third-party hardware.

This accessory is particularly valuable in environments where multiple wireless channels are in use, such as live performance venues, houses of worship, and conference facilities. Rack-mounting keeps cable runs organized, protects equipment from accidental bumps, and makes it easy to access units for frequency adjustments or troubleshooting. The XLR connector standard ensures straightforward integration with existing audio signal chains. While the kit is limited exclusively to Sennheiser's XSW product line, users already invested in that ecosystem will find it an essential addition for maintaining a clean and reliable audio rack.
