Radial Cube

The Radial Engineering Cube is a desktop power rack capable of housing three modules. While many 500 Series enclosures are specifically designed to be mounted, the Cube is the result of an entirely different philosophy. Its compact chassis and convenient top handle make it an inherently portable desktop unit that can be transferred around the studio in accordance with one’s needs. For example, an engineer could use the cube to place an instrument as close to the source material as needed, allowing for a greater signal-to-noise ratio. 

The Cube is conveniently backwards compatible with older API modules, as well as other Radial modules. It features 48V Phantom Power that sends 10mA of current to mic preamps. There are XLR connections for each slot, as well as 1/4” TRS connectors that allow for multing, cross-patching, and parallel processing. 
Rather than being content with the hardwire patch system employed by more traditional power racks, the Cube features an intuitive feed function that essentially configures the modules in series, completely negating the need for patch cables. What’s more, stereo modules can now be synchronized at the mere flick of a switch.
