Radial Engineering Powerhouse 10 slot 500 Series Rack - Used  From Radial

The Radial Workhorse Powerhouse is one of those pieces that isn’t about tone—it’s about unlocking everything else in your rack.

At its core, it’s a 10-slot 500 series chassis, but what makes it stand out is how thoughtfully it’s designed for real-world use. The build is solid and road-ready, with a heavy steel chassis that keeps things quiet and reliable even in demanding setups.

Where it really earns its name, though, is in the functionality. The Powerhouse isn’t just a place to hold modules—it’s a routing tool. The feed function lets you link adjacent modules without patch cables, and the stereo link switches make pairing compressors or EQs quick and painless. It turns your 500 series rack into a flexible, modular signal chain instead of just a collection of individual pieces.

Power is another big part of the story. With a robust 1600mA supply, it handles modern, power-hungry modules—including tube designs—without breaking a sweat. That kind of headroom matters more than you might think, especially as racks get more complex.

In use, it’s all about workflow. Between the individual XLR and TRS I/O on every slot and the ability to cross-patch internally, you can build, tweak, and experiment with signal chains quickly—without constantly reaching for a patchbay.

It’s also completely transparent. There’s no audio circuitry in the path beyond what’s needed to connect your modules, so it stays out of the way sonically and lets your gear do what it’s supposed to do.

For engineers building out a serious 500 series setup, the Powerhouse lives up to its name. It’s not just a rack—it’s a foundation that makes your modules more powerful, more flexible, and a lot more fun to use.

This unit is in excellent working condition. It has some cosmetic blemishes. Mainly scratches from racking. The faceplate has a slight bow but it does not interefer with racking the unit or installing or removing modules.
