FabFilter Pro-MB

Pro multi-band compressor & expander

SKU: FAB0013 Categories: , , , Tags: ,


Multiband compression and expansion are powerful tools, but notoriously difficult to set up and control. Enter FabFilter Pro-MB: making multiband dynamics processing intuitive yet powerful at the same time.

FabFilter Pro-MB introduces a unique Dynamic Phase processing mode. It has virtually the same frequency response as traditional multiband processing, but doesn’t introduce latency or pre-ringing, and only introduces minor phase changes when the gain actually changes. Of course, we have also included an excellent Linear Phase mode and a traditional Minimum Phase mode.

The powerful combination of high quality processing, optimized workflow using the interactive multiband display and all the expert features you need, makes Pro-MB both a lifesaver and timesaver!


– Up to six processing bands, freely placed anywhere in the spectrum
– Bands can be easily snapped together to form a traditional crossover system
– Unique Dynamic Phase processing mode featuring zero latency, no static phase changes and no pre-ringing artifacts
– Excellent Linear Phase processing mode, eliminating audible artifacts when quickly changing crossover frequencies
– Minimum Phase processing mode
– Handles any form of dynamics processing, from highly transparent compression, limiting and expansion to pumping upward compression and punchy gating
– Fully customizable per band: threshold, range, attack, release, output gain, ratio, variable knee, lookahead (up to 20 ms), variable stereo linking, mid- or side-only processing, external side chain input, triggering on a separate frequency range
– Steepness of each crossover slope can be freely adjusted between 6 dB/oct and 48 dB/oct
– Intelligent, highly program- and frequency-dependent attack and release curves
– Global dry/wet mix from 0% to 200% to easily scale the total effect of the plug-in
– Unique interactive multiband display, designed for an optimal workflow
– Accurate and smooth real-time frequency analyzer with pre- and post-processing options and ‘freeze’ feature
– High-quality audio processing algorithms with 64-bit internal processing where needed
