The Radial J-Rak 4 turns your collection of standalone DI boxes into a professional rackmounted system, maximising both space and efficiency in your setup. This clever 1RU solution accommodates up to four compatible Radial products in a standard 19" rack, making it perfect for touring companies and permanent installations alike.
Installation couldn’t be simpler — just remove the outer shell from your existing Radial units and slide the inner frame directly into the rack slots. Most Radial direct boxes, splitters, isolators and Reampers are compatible with this system, giving you the flexibility to create custom rack configurations tailored to your specific needs.
For touring professionals, the J-Rak 4 represents smart inventory management, allowing you to repurpose your existing DI collection for applications like keyboard rigs where rackmounted solutions are preferred. The wide compatibility across Radial’s interface and mic-splitter range means you can quickly assemble purpose-built racks for any application.
- Safely rackmount most Radial boxes
- Easy installation
- Perfect for both touring and studio use
