FabFilter Pro-MB: The Standard in Multiband Dynamics

Harness the might of multiband compression and expansion with FabFilter Pro-MB, an innovative solution for precise and efficient multiband dynamics processing. It deftly combines power and intuitive design, making it simpler to set up and control, while delivering remarkable results.

Revolutionary Approach to Multiband Dynamics

Moving away from the traditional method of splitting the spectrum using crossovers, Pro-MB empowers you to craft a new band in the specific frequency range you want to modify. The philosophy is simple - focus on bands, not on crossovers. The clear interactive multiband display indicates that the remaining spectrum remains undisturbed. If you wish, you can conveniently snap bands together to mimic a traditional crossover system.

A Game-Changer and Time-Saver

FabFilter Pro-MB pioneers a distinctive Dynamic Phase processing mode, offering virtually the same frequency response as traditional multiband processing, but without latency or pre-ringing and only minor phase changes when the gain changes. We've also incorporated an outstanding Linear Phase mode and a conventional Minimum Phase mode. Coupling top-notch processing with the ease of use offered by the interactive multiband display and a suite of professional features, Pro-MB not only saves your time but also enhances the quality of your work!

FabFilter Advantages

As usual, you receive the typical FabFilter benefits: flawlessly adjusted knobs, MIDI Learn, Smart Parameter Interpolation for smooth parameter transitions, a comprehensive help file with interactive help hints.
