Radial R500-PSU 15V Power Supply for Workhorse 500 Series Racks

Radial R500-PSU: The Universal Supply That Powers a Workhorse 500-Series Rack

The Radial R500-PSU is a universal external power supply that delivers regulated plus and minus 15 volts and plus 5 volts at 500 milliamps to Radial's Workhorse 500-series racks and rack-mount tools through a locking 4-pin XLR connector. It is the factory-matched replacement for the adapter that powers a Cube or PowerStrip chassis, so a lost or failed supply never has to take a rack of 500-series modules offline. When an entire lunchbox of preamps goes dark before a session, the correct supply back in hand is the difference between a scrapped day and a working one.

Why the Right Rails and Connector Matter

A Workhorse 500-series rack distributes power to every module in its slots, and those modules expect clean plus and minus 15-volt rails for their audio circuitry plus a 5-volt rail for logic and metering. Feed a rack the wrong voltage or an unregulated supply and you invite noise, erratic behavior, or damage across everything plugged into it. The R500-PSU removes that risk by delivering the exact regulated rails Radial specifies, through the locking 4-pin XLR plug the chassis is built to accept, so power to a full rack stays clean and secure.

One Supply Across the Radial Rack Lineup

Beyond the Cube and PowerStrip 3-slot racks, the R500-PSU is the specified supply for a long list of rack-mount Radial products, including the JDV active direct box, the Headload guitar amp load box, the JX62 amp switcher, the SW4 and SW8-USB switchers, the KL-8 keyboard mixer, and the mPress broadcast press box. Its universal input accepts any mains voltage from 100 to 240 volts at 50 or 60 Hz, so a single supply powers your rig at home and follows it to any stage in the world.

Who the R500-PSU Is For

The R500-PSU is for the engineer running a Workhorse Cube or PowerStrip who needs a dependable spare on the shelf, the touring tech powering Radial rack gear across different countries and voltages, and the studio owner who wants the exact factory-matched supply rather than a risky generic substitute. If a Workhorse rack or a rack-mount Radial tool is part of your setup, this is the supply that keeps it powered and quiet.
