The Cube from Radial Engineering is a three-module desktop power rack designed to bring the fun and excitement of 500 series modular audio to a much broader audience.

Unlike other 500 series enclosures that are usually rack mounted, The Cube is designed to sit on the desktop or be carried around the studio using the convenient top-mounted handle. This enables the engineer to position instrument and microphone preamps as close to the source as possible for improved signal to noise. The Cube can also be recessed into the work surface using the optional mounting flanges. These allow either flush mounting or 30 angle mounting to optimize viewing position.

Following the criteria established by the Radial Workhorse, the Power Strip is 100% backwards 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 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 ΒΌ" TRS connectors for multing 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 of a cable. And stereo modules no longer need to be soldered to be paired, they can now be sync'd together using a simple switch. The Cube is also equipped with Omniport on each sot. This TRS jack enables the module manufacturer to implement a unique function for a given module such as a key input on a gate.

Nice Rack

Comments about Radial Engineering Radial Workhorse Cube Desktop Power Rack:

Radial could have simply put a three-slot frame in a box, called it quits, and still would have had a good idea. Instead they went ahead and made it awesome by adding just a few extra touches, and now I can't look at my standard API lunchbox the same way anymore. First, the size of the Cube is just right for a single input channel, with room for a pre-amp, a compressor, and an EQ, de-esser, or whatever your favorite module is for sweetening your sound. It has a proprietary external AC power converter, with a 4-pin XLR connection, presumably to limit electrical noise inside the chassis, but it also keeps the Cube itself small enough for the second cool feature: with a set of accessory ears, the Cube can be recess-mounted in your work surface, either flush or at an angle. Carry it out to the club, or make it part of your permanent studio setup - it's your choice. The third cool feature is the integral connectivity between modules, giving you the choice (switchable from the back panel) of passing audio internally, or through the usual compliment of external jacks. Modules which can be paired for stereo operation may also be routed integrally, rather than with special board-to-board jumpers. Which is a good thing, because if there is one drawback to the Cube it is a tight fit, making it a bit of a pain to align modules with no vents or other apertures through which to see the module cards fitting into their slots on the backplane. Fat modules, such as the Burl B1D (huge transformer)or Moog's "The Ladder" (with a full sheetmetal enclosure) required a bit of finesse to seat them next to one another. But, I digress. The Cube is a dense little chunk of well-made, thoughtfully designed audio equipment in a convenient size with just the right compliment of useful features.
