Desktop power supply

Following the criteria established by the Radial Workhorse, the Cube is 100% backward compatible with older API modules while being optimized for Radial’s expanding range of preamps, processors and routing devices. Construction begins with a 14 gauge steel frame and features dual gold contact EDAC 15-pin connectors for optimal signal transfer. To maximize the headroom, the external supply delivers 500mA of current for power hungry modules plus a separate 48V phantom tap delivers a full 10mA of current for microphone preamps. Rear panel connectivity includes standard XLRs for each slot along with ¼” TRS connectors for multiple modules, cross patching, and parallel processing. Instead of the traditional ‘hardwire patch’ system employed by others, The Cube employs an innovative feed function that patches modules together in series without the need for a cable. And stereo modules no longer need to be soldered to be paired, they can now be synced together using a simple switch. The Cube is also equipped with Omniport on each slot. This TRS jack enables the module manufacturer to implement a unique function for a given module such as a key input on a gate.

The Radial Cube is a compact desktop 3-slot 500 series power rack that follows the guidelines set out in the Workhorse open-source document (Whos-Doc). This accommodates the very latest Radial modules while being backward compatible with older formats. Regarding the audio performance – there is no audio circuitry other than connectors. The Cube will not impart any color, distortion or artifact. The Cube employs Edac gold plated 15-pin card-edge connectors on the inside and Neutrik connectors with non-tarnishing nickel-silver contacts on the back panel for excellent signal transfer. Each slot is equipped with an auto-resetting fuse to protect the system should a faulty module be employed. A 500 milliamp external supply provides plenty of current to feed the modules and 48V for phantom power.
