! IMPORTANT SAFETY & USER NOTICE - FOR PROFESSIONAL USE The Radial Workhorse Cube is specifically designed for use by qualified professional audio engineers. The open frame design is not intended for use by consumers or those unfamiliar with this format. Even though the current and voltage levels are relatively low, we recommend that all slots be filled with a module or covers be placed over unfilled slots. This will help protect you from electrical shock.

® True to the Music INTRODUCTION The Cube is a three card-slot power frame designed for 500 series modules. Up to three modules may be used at any one time. The Cube routes the modules to the XLR and ¼” TRS connectors on the rear panel via a 15-pin card-edge receptacle. Radial modules and those that have been designed by other manufacturers to take advantage of the Workhorse’s extra features will enjoy the added functionality of the Omniport™.
® True to the Music FEED SWITCH As you delve further into the functionality of the 500 series, you will find that the modular format allows all kinds of connectivity options. With older 500 series racks, connections between modules were done using an XLR cable whereby the output from one module would plug into the input of another. The Cube simplifies the process by introducing a FEED switch on the rear panel.
® True to the Music OMNIPORT Omniport™ is a special ¼” TRS jack located on the rear panel that has been left ‘open’ to allow the module to perform a unique task. In other words, depending on the type of module, the manufacturer can assign the Omniport to perform a function that may be most appropriate. This could be a key input on a gate, a TRS insert or maybe a buffered output.
® True to the Music POWER SUPPLY The Cube employs a external power supply that will automatically convert the various voltages used around the world and regulate them before sending the power to the Cube. A standard male IEC/EIN power input connector makes it easy to travel as you need only change the cable to suit the local power connector type. The connection between the power supply is a 4-pin locking XLR.
® True to the Music SETTING UP THE CUBE The Cube is designed to either sit on the desktop or be mounted into the desktop using the optional mounting brackets. For desktop use, four rubber feet are included in the packaging. To install the rubber feet, turn the Cube upside down and insert into the four open holes on the bottom. The Cube also comes with a convenient carry handle that makes it easier to move the Cube around the studio.
® True to the Music ATTACHING BRACKETS The brackets attach to the top and bottom of the Cube using two screws for each part. Remove the top handle and attach the brackets as shown. The top bracket attaches to the same threaded screw holes as the top handle. ANGLE MOUNT Part# R700 0107 03 FLUSH MOUNT Part# R700 0107 02 CUTTING OUT THE DESK -TOP Once the brackets are fastened to the Cube you will need to cut out a hole in your desktop. Use the dimensional data below to mark an opening sized for the Cube.
® True to the Music INSTALLING MODULES IN THE CUBE When making any electrical connection, it is always safer to do so with the power disconnected. The Cube’s internal power circuit is equipped with protective measures intended to provide a margin of safety should a module exchange be performed with the power on. However, the Cube is not designed to allow repeated insertion and removal of modules while the power supply is active. Always power off the Cube before exchanging modules.
® True to the Music SIGNAL FLOW AND LEVELS Because the Cube is modular, it can accept a multitude of different devices into it’s card slots. This also means that you need to understand the signal flow so that you can be sure what you want to do will work. In the world of audio there are basically four low level signal groups to contend with before you get to high power output levels such as those produced by power amplifiers to drive loudspeakers.
® True to the Music USING THE CUBE Because the Cube is a modular frame, there are practically no limits as to what kind of signal chain you can create. For instance, it can be loaded with Radial modules set up for analog effects routing for your workstation, a customized channel strip, an instrument preamp for live recording or as part of a play-back and overdub system. As with all electronic equipment, turn off the power and turn down levels before making connections.
® True to the Music The Cube simplifies the process with a FEED switch that replaces inter-module patch cables. Instead of using an XLR cable, you simply push the FEED switch into the UP position and it routes the signal to the adjoining module’s input. When engaged, the FEED function sends the signal to the next module working from left to right (front view). Because the FEED function is tied to the XLR connector, it will work with new Radial modules and older 500 series modules.
