A startling recreation of the world's finest echo chambers.

Located below the iconic Capitol Tower in Los Angeles, Capitol Studios is arguably the most recognized studio in the world — and much of its legend can be traced to its hallowed, subterranean echo chambers. From Ray Charles to Frank Sinatra, Beck to Muse, these underground spaces continue to provide gorgeous hi-fi ambience that is simply unmatched.

Now, after years of R&D and close collaboration with Capitol Studios — including unprecedented access to four legendary echo chambers 30-feet beneath the studio — Universal Audio proudly presents the Capitol Chambers plug-in, a startling end-to-end recreation of the most popular echo chambers ever created, exclusively for UAD hardware and UA Audio Interfaces.

Now You Can:

Record and mix with the world's only authentic plug-in emulation of Capitol Studios' prized underground echo chambers

Add the unmistakably dense, natural reverberation to vocals or drums — far beyond plate, digital, or simple convolution reverb

Create new sounds by repositioning Capitol Chambers' microphones using UA's Dynamic Room Modeling

Audition current and historical chamber configurations, plus new setups curated by Capitol's Steve Genewick

Harness the chamber's entire signal chain including amplifiers, speakers, custom preamps, and mics

Quickly pull up presets from legendary Grammy-winning engineers Al Schmitt (Ray Charles, Steely Dan), Darrell Thorp (Beck, Radiohead), Frank Filipetti (Madonna, Paul McCartney) and more

Classic Echo Chambers Designed by Les Paul

Classic Echo Chambers Designed by Les Paul

Prized for their natural sound and dense ambience, acoustic echo chambers became a creative tool for pioneering, forward-thinking engineers by the mid 1940s — most notably UA founder Bill Putnam Sr. and the great Les Paul, the genius behind the Capitol chambers designs. Built from reinforced concrete and tuned using sloped ceilings and a trapezoidal shape, Paul's designs deliver a smooth, balanced decay and a completely natural room tone that can't be achieved in any other way.

Capturing Iconic Echo

Capturing Iconic Echo

In creating this amazing plug-in, UA sourced historic technical diagrams from the early '60s to precisely recreate microphone/speaker setups inside of Capitol's most coveted chambers, including the vintage omnidirectional Altec 21D mics and custom speaker/horn configurations, in their original hit-making positions. Current "modern" configurations dating from the late '80s were also captured, using the omnidirectional Shure SM80s, while new and creative mic/speaker combos were devised by Capitol's resident chamber expert, Steve Genewick.

Unprecedented Ambience Control

Unprecedented Ambience Control

Capitol Chambers' Position slider gives you next-level control over spatial and time response, allowing you to reposition the chamber mics — no assistant engineer required. From the maximum distance stock positions, to direct speaker-to-microphone effects and proximity characteristics, the Capitol Chambers plug-in can subtly thicken vocals or drums, or soak strings with the most natural, complex sounding reverb ever recorded.

Powered by UA's Dynamic Room Modeling

Powered by UA's Dynamic Room Modeling

Harnessing the same technology as the 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 the Capitol Chambers plug-in nearly infinite ambient possibilities.

Deeper Still

Deeper Still

Beyond a vintage recreation, the Capitol Chambers plug-in 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. In addition, the Width control allows you to narrow the chamber's stereo field, for easily pinpointing a vocal or instrument in the mix. Finally, Decay lets you quickly shorten Capitol Chambers' natural reverb time, offering more scenarios to harness the most famous echo chambers ever made.

An All-Star Collection of Artist Presets

The glue

Can one good reverb make a difference? the answer is yes. It is the frank's hot sauce of reverbs. You can use it use it a bit, you can use it a lot and it goes with everything. I would like some John Bonham drums please, CHECK. I need to sweeten up this piano riff, CHECK. Vocal, oh the vocals , it is hard to make things sound bad. best money i have spend since i got my Apollo Twin. Top Shelf!

My go-to reverb.

I really love this reverb plugin. It's dense, dark and delicious. I've been using it globally on my mixes and I love the way it glues everything together without being over the top. I sometimes run it on an acoustic guitar bus to give a little extra lusciousness... it also sounds great on open-back clawhammer banjo!

I also love plate and spring reverb, but this one just seems to be my go to. Be aware that it is DSP heavy, but that is to be expected given the complexity of what it's actually doing!

SOooooooo...

as I write this review, the CC plug-in shuts off and say there's not enough DSP even though I'm using (2) satellites showing 39% DSP used.....hopefully I can get it running...

Wow!!!

The first time I tried the Capitol Chambers reverb it absolutely blew me away. It’s the most musical reverb I’ve ever used. It inspires and gives an instant timeless quality to almost every source. The painstaking process Universal Audio went through modeling the room, vintage mic’s and speaker IR’s is apparent from square one. Such a great tool to have in the box!!!

A timeless sound and easy-to-use masterpiece

If you want a reverb sound that sounds like a record, this is it. Whether you want an instant ‘60s vibe or something modern, this famous chamber is the go-to for creating the timeless sounds artists and producers are still talking about and trying to capture today.

With a retro-styled, ultra-simple user interface, being able to choose the mic, room, and even mic distance is the next best thing to being in this legendary LA studio.

Try the demo. You won’t be disappointed.

The retro-styled interface is inspiring and informational showing the various mics, rooms, and even mic distance to capture the right sound for any production.

Capital Chambers

first time I demo this thing, I was blown away by the quality of Reverb, and to use the different mic position, take me back to school when setting up for tracking a session. I have made this reverb part of my template.

Really good... as expected

This is a really good addition to my reverb collection... the missing link between the EMT140 end the BX20. With a lot of flexibility thanks to the well-thought settings : Pre Delay / LPF / EQ ... The emulations are good as expected from UA ! >Good job guys

Awesome reverb!

This is a great reverb! It sounds ”ready” on pretty much anything I’ve fed it with (vocals, drums, acoustic guitars). Lush, wide (or narrow if you want to), big, small but never harsh. The ui is super easy to understand. Very very nice indeed!
