Capitol Chambers Black Friday pricing is 25% off, $149, with the deal ending Nov 30, 2026, on Universal Audio's echo chamber plugin built around the underground spaces below Capitol Tower in Los Angeles.
Those chambers have been part of records by Ray Charles, Frank Sinatra, Beck and Muse. The plugin is a reverb that puts your tracks in that room.
UA says it worked from historic technical diagrams from the early '60s to recreate the microphone and speaker setups inside the chambers. That includes the vintage omnidirectional Altec 21D mics and the custom speaker and horn configurations.
The current setup with omnidirectional Shure SM80s is in there too. Every mic sits in its original hit-making position.
The maker says it can subtly thicken vocals or drums, or soak strings in reverb.
The Position slider lets you move the chamber mics and changes both the spatial and the time response. Positions run from the furthest preset placements to close, speaker-on-mic proximity behavior.
It runs on UA's Dynamic Room Modeling, a mix of physical modeling and advanced measurement techniques. The maker says a standard convolution reverb only gives you a sonic snapshot, while this approach opens up nearly infinite ambient possibilities.
Beyond the vintage recreation, you get controls built for a modern DAW session:
The plugin covers the chamber's whole signal chain: amplifiers, speakers, custom preamps and mics. You can audition current and historical chamber configurations, plus new setups.
Presets come from engineers and producers including:
UA lists more names beyond those four.
Two versions come with your purchase:
It works with any audio interface, so UA hardware is not required.
Yes. The Capitol Chambers Black Friday deal is 25% off, bringing the plugin to $149. The offer ends Nov 30, 2026. Both the UAD Native version and the Apollo Realtime and UAD-2 version come with your purchase.
No. UA says it works with any audio interface. The UAD Native version runs on your Mac or PC without UA hardware. If you own an Apollo interface or UAD-2 hardware, the Apollo Realtime and UAD-2 version runs accelerated on it.
It lets you reposition the chamber mics, which changes the spatial and time response. Capitol Chambers lets you place the mic anywhere between the farthest standard spot and right up against the speaker, with proximity characteristics shifting along the way, so one chamber can sound very different from setting to setting.
You get Pre-delay, Dry/Wet mix and Decay. A sweepable 80 to 750 Hz filter keeps muddy bass out of the chamber. Bass, Treble and a Mid band with proportional Q shape the ambience, and artist presets are included.
