What is a Multiband Compressor

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 contains 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:

Leon Todd's tutorial on applying Andy Sneap's multicompression trick to improve palm muting

Configure the Multiband Compressor

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

Leon Todd shows how to dial in the MBC for high-gain tones

Or just check factory preset: Multicomp Plexi.
