Black Lion Audio PBR8 8-Slot 500 Series Power Rack Enclosure

The Black Lion Audio PBR8 is an 8 slot 500 series rack and power supply with a built in, fully balanced TT patchbay that makes routing your modules fast, flexible and incredibly intuitive. Designed for engineers who constantly experiment with signal chains, it lets you reconfigure your entire 500 series workflow from the front panel without touching a screwdriver.

Fitting eight 500 series slots into a rugged 3U rackmount enclosure, the PBR8 is equally at home in a permanent studio install or a mobile rig. With per channel power regulation, high current audio rails and carefully engineered low noise performance, it delivers clean, stable power for modern and vintage hungry modules alike.

Creative 500 Series Routing

The PBR8 is built around Black Lion Audio’s patented front mounted TT patchbay, giving you inputs and outputs for every slot plus two mults. That means you can build, audition and tweak complex processing chains in seconds, split signals for parallel processing, or send audio to and from other racks without ever reaching behind your gear. For busy sessions and fast moving creative work, it turns your 500 series collection into a truly modular playground.

Rock Solid, Low Noise Power

Drawing on Black Lion Audio’s long experience in modding and optimising studio hardware, the PBR8 provides exceptionally stable and quiet power. Each slot benefits from its own power regulation to minimise noise and crosstalk between modules, while the hefty supply delivers up to 400 mA per rail per slot, with an overall 1.6 A (1.8 A non continuous) per rail available. The result is reliable performance and consistent sonics, even with demanding modules installed.

Stereo Linking Made Simple

If you run stereo compressors, EQs or preamps, the PBR8 makes linking adjacent modules straightforward. A dedicated stereo link function lets you pair slots at the touch of a button, while internal jumpers are available for less common linking configurations. It is a fast, practical way to configure stereo chains without re patching or re racking your modules.

Rugged, Studio Ready Build

The PBR8 shares the same robust construction as Black Lion Audio’s PBR series patchbays, with a black anodised aluminium front panel and a chassis drilled to optimise heat dispersion. Gold plated XLR, TT and DB25 connections maximise conductivity and signal integrity, while the custom tensioned TT jacks are designed for long term reliability in demanding studio environments.

• 8 Slot 500 Series Rack with Built In Patchbay - House up to eight 500 series modules in a compact 3U chassis while gaining instant access to every input and output from the front panel. This integrated approach saves space, simplifies cabling and turns your 500 series collection into a flexible, reconfigurable processing hub.
• Patented TT Patchbay with Mults - The front mounted, fully balanced TT patchbay provides dedicated ins and outs for each slot plus two mults for splitting signals. You can build complex chains, experiment with parallel processing and integrate external racks quickly, all without reaching behind your gear or changing your physical module layout.
• Clean, Isolated High Current Power - Per channel power regulation and high current audio rails help keep noise and crosstalk to a minimum, even with power hungry modules. With up to 400 mA per rail per slot and generous overall current capacity, your modules get the stable, low noise power they need to perform at their best.
• Premium Connectors and Rugged Construction - Gold plated XLR, DB25 and TT connections ensure excellent conductivity and long term reliability, while the robust chassis and black anodised front panel are built to withstand daily studio use. The carefully ventilated design also aids heat dispersion, helping to keep your modules running smoothly.
