Description
Resources

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.

High-current, low-noise

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.

Great kit, very clear instructions, super easy to build. Took about an hour.

one of a kind chassis

PR502 is an extremely easy build and an absolute blast to assemble. I ordered the PR502, CP5 and the Royal Blue Colour Module as my first project and was NOT disappointed in the outcome.

phenomenal designs, deliberate/attentive manuals, and astronomical end-results.
immensely similar to products the industry spends thousands of dollars on for equivalent results.

another pro for the PR502 is that you can buy 2 slots at a time. as you need more, you can add other chassis’ to the chain.

Solid and reliable after 1 year

I found this as a solution for portable preamp/compressor for tracking vocals on the road. I filled it with an API 512V + DBX 560A (Revive mod) and It's become one of my go-to vocal chains. Has worked flawlessly after a year.
My suggestion for improvement is an on/off switch.
If there was an option for a smaller, more portable power supply that would also be cool.
But overall I give it 5 stars and I look forward to checking out more of their gear. Thanks!

PR502 500 Series

I really like this Kit, very easy to built, nice size.

Can be easily portable, or racked.

I like the material specially the PCB and the rear panel.
The finish of the paint and the panels looks very good.

It lack of a pole in the front and rear so it feels more sturdy when handling, but that its easy fix. You can use metal, wood and different bumpers. If you racked then is not a problem.

Its also good you can assemble it, that way you can use the parts or solder of your like.

All screws and parts are very tight, and feel really good.

The option to add more in series is really great. The cable feels of good quality.
The power supply look a little big and his plastic feels cheap, but its a power supply, so if works who cares.

I think, i will be buying more of these. Having more 500 Series are very versatile and using the same power supply for this its great.
