Easily Capture Iconic Echo

Easily Capture Iconic Echo

UA sourced historic technical diagrams from the early '60s to precisely emulate microphone/speaker setups inside Capitol's chambers, including the vintage omnidirectional Altec 21D mics and custom speaker/horn configurations and current "modern" configurations using omnidirectional Shure SM80s — all in their original hit-making positions.

Create with Unprecedented Ambience Control

Create with Unprecedented Ambience Control

Capitol Chambers' Position slider gives you next-level control over spatial and time response, allowing you to reposition the chamber mics. From the maximum distance stock positions, to direct speaker-to-microphone effects and proximity characteristics, Capitol Chambers can subtly thicken vocals or drums, or soak strings with the most natural, complex sounding reverb ever recorded.

Explore UA's Dynamic Room Modeling

Explore UA's Dynamic Room Modeling

Harnessing the same technology as UA's award-winning Ocean Way Studios plug-in, Capitol Chambers uses UA’s proprietary Dynamic Room Modeling technology, an exclusive combination of physical modeling and advanced measurement techniques. Whereas standard convolution reverbs only provide a sonic snapshot, Dynamic Room Modeling gives Capitol Chambers nearly infinite ambient possibilities.

Go Deeper Still

Go Deeper Still

Beyond a vintage recreation, Capitol Chambers offers creative features for modern DAW workflows like Pre-delay, Dry/Wet mix, and Decay controls. A sweepable 80 to 750 Hz filter lets you minimize muddy bass going into the chamber, while Bass, Treble, and proportional Q Mid band lets you perfectly season the chamber's lush ambience.

Harness All-Star Artist Presets

Harness All-Star Artist Presets

The Capitol Chamber's plug-in features carefully crafted presets from a stunning roster of Grammy-winning engineers and producers, including the late Al Schmitt (Ray Charles, Steely Dan), Mark Linett (The Beach Boys, Los Lobos), Frank Filipetti (Madonna, Paul McCartney), Darrell Thorp (Beck, Radiohead), and many more.

Reverb royalty

This reverb has an iconic character, wrapping a royal mantle around any signal…..conjuring majestic sounds once only available to a select few, with a mere mouse-click on your laptop.

The Real Deal

Having worked at Capitol, I can say this plugin captures the Capitol vibe completely, it sounds great on anything you throw at it. I own a few other Camber IR reverbs, and this is my favorite, worth every penny

Irreplaceable for me now

I have all sorts of reverbs, and many of them very very good, but this is a sound unlike any other. The uniqueness of the way they cleverly created all these reverbs back in the day is so special, I can't live without it now.

It just works... and sounds great

Beautiful sounds, good presets as starting points, and very intuitive to use. I was concerned it might be a real drag on my computer but (at least, using it sensibly on a few aux/bus channels) it's fine. I use this all the time now

Lush Reverb

I really like Capitol Chambers for lush reverbs on vocals and acoustic instruments. Sounds great on an organ and rhodes or a standard piano. Unique reverb and easy to use.

Interesting understanding of customer orientation

UAD waits until you have bought a plugin for full price and sends you exactly one day later a loyality price offer for same plugin. I like their sense of humour :-D

Lush. Vibrant. Eternal.

Maybe it’s my imagination but I do feel like I’m forty feet beneath the Capitol Tower in Hollywood and the voice of Frank Sinatra is reverberating in my headphones. This is a near-magical plug-in. Soulful. Highly recommended.
