Polish your masters to perfection with the Capitol Mastering Compressor Plug-In from Universal Audio. The software painstakingly recreates the CM5511, a tube-driven compressor/limiter model used in all four of Capital Studios mastering rooms on historic catalogs and modern hit records spanning multiple genres.

Designed expressly for mastering but useful on a variety of sources, the CM5511 includes stepped controls for easily repeatable results, with familiar input, threshold/attack/release controls, an internal sidechain to filter out low bass in the compressor detector, and extra features included with the mastering engineer in mind. Use the Saturator, Mix, and Headroom controls to easily increase perceived loudness and texture in your productions, while the Mono Fold and Mid-Side features allow you to tighten low end and expand stereo width. This plug-in software download includes a native version that will run on Mac and Windows computers without UA hardware as well as a second version that runs accelerated on Apollo interfaces and UAD-2 hardware.
