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.
2.0 Update: As of January 2020 we are shipping a revised version that features a simplified build process. This version cannot be daisy-chained with the pre-2020 version. To request an earlier version of the kit please contact us.
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
Assembling the PR502 is safe and easy, thanks to the external power supply and our step-by-step instructions.
Estimated build time: 1 hour
Note: 500-series modules from Rupert Neve Designs (RND) are slightly wider than the API spec and as such will not fit in the PR502.
