Portico II Master Buss Processor Black

The Rupert Neve-designed Master Buss Processor features transformer coupled I/O and high-voltage 72V circuitry, enhancing headroom, clarity, and musicality. Its precision controls manage dynamics, tone, and stereo width with mastering-grade accuracy.

The compressor section offers versatile dual-mono/stereo operation with adjustable ratio, threshold, attack, release, blend, side-chain HPF at 125Hz, and selectable feed-forward/feed-back modes for modern or vintage compression styles. Parallel compression via the Blend knob maintains natural dynamics.

The intelligent limiter employs Adaptive Release Technology for transparent, distortion-free limiting, effectively handling both transient and sustained signals using shared discrete class-A gain modules and VCAs to ensure pristine signal integrity.

PSU works on 100-240V, EU power cord included.
