A legend wrapped in Marinair transformers.

Inspired by the iconic Neve 2254 compressor/limiter, the BB N54 delivers rich, analog warmth and musical dynamic control straight to your DAW. Designed in partnership with Blackbird Studio and tuned to John McBride’s personal taste, it captures the unmistakable low-end weight and harmonic depth that made the 2254 a studio essential.

Dial in classic compression with ease. The BB N54 combines dual-stage compression and limiting with a modern workflow, giving you the power to add cohesion, warmth, and character to any track—without the hassle of complex setups.

• Dual — Provides Stereo Linked/Unlinked & Mid/Side processing.
• Single — Provides Stereo or Mono-compatible processing.
• Input, Output Trim and Meters — Input and Output trim controls provide ( +/- 36 dB ) gain staging in and out of the plugin. The Output trim also acts as your ‘make-up gain’ control should only the compressor be engaged.
