Black Lion PBR-8 500: A 500-Series Rack with Patching Built In

The Black Lion Audio PBR-8 500 is an 8-slot 500-series rack and power supply with a built-in balanced TT patchbay, combining hosting and routing in one 3U chassis. It powers eight 500-series modules and brings each slot's input and output to a front TT patchbay. That means you re-route modules from the front instead of recabling the rear. In three rack spaces it merges a module rack, a power supply, and a patchbay.

What the 500-Series Format Offers

The 500-series is a modular standard where preamps, EQs, compressors, and other processors slide into a shared rack. A host rack supplies power and connectors so you can mix and match modules from many designs. This unit provides eight slots, each ready to accept a standard 500-series module. That lets a studio build a custom channel strip and swap modules as needs change.

A Patchbay That Frees Your Modules

Building a TT patchbay into the rack is uncommon and genuinely useful. Every slot's input and output appears on a front balanced TT patchbay, so signal routing changes at the panel. You can reorder processors, feed one module into another, or bypass a slot without touching the rear. That turns a fixed module lineup into a flexible, re-patchable signal chain.

Two Mults for Parallel Routing

The front panel also includes two mults, each splitting one input into two outputs. Mults let you send a single source to two destinations for parallel processing or distribution. Paired with the built-in patchbay, they open creative routing right at the front. That is the kind of flexibility usually reserved for a separate patchbay.

High-Current, Regulated Power

The internal supply runs on 100 to 240 volts AC and regulates power per channel to isolate each slot. Each slot draws up to 400 milliamps per rail, with an overall limit around 1.6 amps per rail. Maximum phantom power current is 140 milliamps for demanding modules. Per-channel regulation keeps noise and crosstalk between modules low even under heavy load.

Stereo Linking and Rear Connectivity

Adjacent slots link to stereo at the press of a button for paired modules like stereo compressors. The rear panel carries eight XLR inputs and eight XLR outputs plus a DB25 input and a DB25 output. Gold-plated XLR, DB25, and TT connections keep the signal path clean throughout. That combination ties the rack cleanly into a console or interface.

Where the Black Lion PBR-8 500 Fits

Studios and touring engineers use the PBR-8 500 to host a modular channel strip that re-routes on the fly. Because the patchbay is built in, module order and parallel paths change without moving hardware. High-current regulated power supports demanding preamps and processors reliably. It suits anyone who wants a 500-series rack and a patchbay in one road-ready unit.
