Radial Engineering Cube Portable Desktop 500 Series Power Rack

The Radial Engineering Cube 3-Slot Power Rack is a compact and portable desktop 500 Series power rack designed to make modular audio accessible to everyone. Capable of housing up to three 500 Series modules, it delivers a powerful and versatile solution for building custom channel strips, guitar front ends, and creative processing chains. Fully compatible with Radial modules and older API systems, the Cube provides up to 500mA of shared current, with an additional dedicated 48V phantom supply for microphone preamps.

Built from rugged 14-gauge steel, the Radial Engineering Cube is engineered for reliability and durability, with dual gold-contact EDAC 15-pin connectors ensuring optimal signal transfer. Its external desktop power supply maximises headroom for demanding modules, while rear panel connections include XLR and ¼” TRS connectors for flexible routing, cross-patching, and parallel processing. Unlike conventional hardwired systems, the Cube’s innovative feed function lets you patch modules in series without extra cabling. Stereo modules can be paired instantly using a switch, and each slot includes an Omniport TRS jack for unique manufacturer-specific functions such as sidechain key inputs.

Designed for creative flexibility, the Radial Engineering Cube allows you to configure your ideal setup. Combine preamps, EQs, and compressors to form a professional channel strip, build the perfect guitar front end with direct recording, reamping, and cabinet emulation, or integrate pedals and outboard gear into your workflow with ease. With optional angles for recessing into a desktop, the Radial Engineering Cube offers a powerful, portable, and adaptable solution for studios, live rigs, and home recording environments.
