Radial Engineering Workhorse Cube – 3-Slot 500 Series Desktop Chassis

Build your ultimate portable channel strip. The Radial Workhorse Cube is a heavy-duty, 3-slot desktop power rack that brings your favorite 500 series modules right to your fingertips. Whether you are building a dedicated vocal chain, a portable guitar tracking rig, or a high-end analog front end for your home studio, the Cube offers unmatched connectivity and rock-solid Radial reliability.

Why the Cube Stands Out: Radial went far beyond a standard power supply with this unit. It features an incredibly smart backplane with a built-in "Feed" switch, allowing you to daisy-chain modules in series without needing a single patch cable. Add in the TRS I/O and the unique "Omniport" for accessing custom module features, and the Cube easily becomes the most flexible 3-slot chassis on the market.

Key Features:

• Built Like a Tank: 14-gauge steel chassis built for the rigors of studio desktop use or mobile recording.
• Cable-Free Patching: The innovative "Feed" switch patches modules 1 into 2, and 2 into 3 in series with the flick of a switch—no XLR cables required.
• Stereo Linking: Easily sync stereo modules using a simple back-panel switch instead of soldering or using cumbersome jumper cables.
• Extensive I/O: Each slot features standard XLR inputs and outputs, plus parallel ¼” TRS connectors for easy cross-patching, multing, or parallel processing.
• The Omniport: A dedicated TRS jack on every slot allows module manufacturers to implement unique functions (like a key input on a gate or an instrument input on a preamp).
• Clean, Quiet Power: Delivers a generous 500mA of shared current for power-hungry modules, plus a separate 48V phantom tap (10mA) ensuring your condenser mics get all the power they need.
• API Compatible: 100% backwards compatible with older API modules and optimized for modern 500 series gear via dual gold-contact EDAC 15-pin connectors.

Technical Specs:

• Capacity: 3 single-wide 500 series modules
• Power Supply: External power supply (maximizes headroom and keeps transformer noise away from your audio)
• Current: 500mA shared current, isolated 48V phantom power
