PR502 2-Slot 500-Series Chassis Kit with External Power Supply
- Full Kit
- Step-by-Step Guide
The PR502 is a 2-channel, high-current, 500-series chassis in a desktop or 19" rack-mount format. The assembly process is fairly simple, and does not require dealing with wall power.
Rugged and refined
The PR502's minimalist, all-black chassis is made from anodized aluminum and powder-coated steel. The compact case fits into any desktop setup, while the optional rack ears make the PR502 compatible with standard 19" racks.
Our custom, universal power supply provides up to 250mA of clean current per channel—almost double the 500-series spec—and can power up to four PR502 racks (eight modules). Additional filtering and regulating in the chassis ensures that the power for your modules is stable and dead quiet.
Simplicity is a feature
While the PR502 is designed with an emphasis on simplicity, it is a full-featured 500 rack.
- THRU jack for powering additional racks
- LED power indicators for +/-16 and +48v
- Neutrik XLR audio jacks
- FEED feature turns your PR502 into a channel strip by patching channel 1 into channel 2 without a cable
- Compressor link
- 11" x 8" x 1.7" without rack ears
Assembling the PR502 is safe and easy, thanks to the external power supply and our step-by-step instructions.
Estimated build time: 1 hour
This was a straightforward DIY build and the result is a really nice, compact 500-series chassis for two DIYRE modules. I’m going to build another (with the daisy-chained power supply) for my expanding DIYRE module hoard. The audio through this box is as clean as a whistle. Keep up the good work, gents.
The title says it all. Assembly was easy except for my lack of skill installing one XLR jack and remedied by ordering a replacement from Mouser. Two minor niggling issues: 1) Manual doesn't give info on testing and powering up the module and 2) The top and bottom panels tend to sag a little (perhaps a couple small brackets attached to the face plate center leg)? Still very much worth it!
AB SO LUTELY beautiful. package wise, product wise , its JUST AMAZING! Loved it. loved the material, real sturdy, simple and fun to build. Waiting a "few" months (2 weeks max) to buy me a new one, for a pre amp, (before my wife notices it and kills me!!!)
keep up the great work guys!!!!!
Cheers from Mexico!
What a clever, simple design. So neat, so right. Props once again to DIYRE ingenuity.
As a VO actor, I don't need a lot of hardware in my recording chain. This 500 box is just the right size, and easy to build. Perfect fit for my CP5.
