Universal Audio’s New Capitol Mastering Compressor Plugin

Get the legendary tube compressor from Capitol Studios.


19 May 2023

With several years in the making, Universal Audio has released its Capitol Mastering Compressor. The plugin gives you the rich sound of the CM5511 — a legendary hand-built tube mastering compressor designed and used by Capitol Studios on historic catalogs and thousands of hit records. Exclusively modelled by UA, now you can get the same professional finishing touch previously only available at Capitol Studios.

Get the Exclusive Sound of Capitol Mastering
The CM5511 compressor has mastered entire catalogs from Capitol, Motown, Geffen, Blue Note, Def Jam, and dozens more, as well as modern records by Black Sabbath, Demi Lovato, and Selena Gomez. Inspired by vintage Fairchild 670 and Gates Sta‑Level tube limiters — and designed for consistent results across Capitol’s four mastering rooms — Capitol Mastering Compressor is an exacting emulation of this ‘spare no expense’ hardware, giving you the modern tube-based sound of this custom-made dynamics masterpiece.

Tighten low end, add subtle saturation, and tweak the stereo field with easy‑to‑use ‘plug‑in only’ controls. Plus, comprehensive dBFS and LUFS metering and sidechain filter means you have a full-featured, modern mastering tool at your fingertips.

Not just for the 2‑bus, Capitol Mastering Compressor will add its tube‑based magic to your drum bus, synths, background vocals, and more, giving you the gorgeous dynamics control only achievable with this one‑of‑a‑kind, hit‑proven hardware.

Use this plug-in free for 14 days and find out if it’s right for you.
