Get the Legendary Tube Compressor from Capitol Studios.

Capitol Mastering Compressor gives you the rich sound of the CM5511 — a legendary handbuilt tube mastering compressor designed and used by Capitol Studios on historic catalogs and thousands of hit records. Exclusively modeled 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, 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.

Expanded Controls for Complete In‑The‑Box Mastering

Easily 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.

Add Expensive Sound to your Instrument Groups

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.

    Excellent character compressor

    So good on mix bus, especially for vintage, warm tube-based vibes. Push the output for pleasing analog clipping, or dial that back a bit and engage the saturator and shape amount. Mono fold and mid/side options also helpful.

    Love the glue!

    At first I didn't think much of the compression. It sounded good. But after working with it, it really does have a warm glue giving that "album quality" I always heard from albums of the past.
