About multiband compression

A multiband compressor (MBC) consists of multiple compressors working in parallel, each operating on a separate band of frequencies. Fractal Audio's Multiband Compressor blocks consists of 3 compressors. These compressors work independently, so "pumping" in one band does not affect the others. An MBC is often used as a mastering tool.

More information:


In-depth programming of the Multiband Compressor is possible, but even at default settings (placed after Amp/Cab) it's performing fine. [1]

Or just check the factory preset MULTICOMP PLEXI.
