The definitive collection of the world’s most famous compressors.

The original Universal Audio 1176 was designed by UA founder M.T. “Bill” Putnam, and represented a major breakthrough in limiter technology. The first compressor featuring solid‑state circuitry and ultra-fast 20 microsecond FET gain reduction, the 1176 is an easy‑to‑use “desert island” compressor that has lent its character and punch to some of the greatest recordings in history.

Upon its release in 2001, UA’s first 1176 plug‑in single‑handedly launched our UAD platform. Extensive end‑to‑end circuit modeling in 2013 captured even more sonic nuance. Now with updated graphics and additional controls, the 1176 Classic Limiter Collection continues its legacy of analog modeling excellence.

Featuring the 1176 Classic Limiter Plug-In Collection.

A Triple Threat

A Triple Threat

The 1176 Classic Limiter Plug-In Collection provides three distinct 1176 revisions, representing over 40 years of design iterations to the original 1176. The Rev A “Bluestripe” represents the original Putnam FET limiter design, complete with its higher distortion and unique FET gain amplifier characteristics. The Rev E “Blackface” covers the early '70s Brad Plunkett “LN” (Low Noise) era, with variations including a more linear compression response, transistor gain amplification, and a change to the program dependence. The 1176AE provides UA’s rare 1176 40th Anniversary Edition, complete with exclusive mods — including its lower 2:1 compression ratio.

Classic Compression, Quickly

Classic Compression, Quickly

Using an 1176 is a study in simplicity. Input simultaneously sets compression threshold and the level of the signal entering the 1176; Output sets the final signal level. Attack sets the time it takes the 1176 to respond to incoming signal, while Release sets the time it takes the 1176 to return to its initial level. The VU meter displays the amount of gain reduction (GR) or output level (+4/+8).

Ratio Buttons for Iconic Color

Ratio Buttons for Iconic Color

The four Ratio buttons determine the degree of gain reduction — lower ratios for compression, higher ratios for limiting. Disengaging all Ratio buttons disables compression, while continuing to pass signal through the 1176 circuitry, adding unmistakable color. At the request of users, “Multi-Button” combinations possible with the hardware are now attainable in the plug-in — including the famous “All Button” sound.

Added Features for Modern Workflows

Added Features for Modern Workflows

Exclusive plug‑in only features lend modern workflows to this classic processor collection. Get quick parallel processing on bass and kick drums with Dry/Wet mix controls, or use the custom Sidechain Filter to tame low‑frequency pumping. Plus, enhanced graphics with improved VU metering bring iconic FET compression into a new age.

Il top delle emulazioni

Se state cercando delle emulazioni fedeli all'1176 questi fanno al caso vostro. Sono impareggiabili e li stra-utilizzo. Consigliatissimi

very nice work UA

of all the 76 emulations i have tried (and i have tried the lot) this gives a slightly wider soundstage and is mid forward and can bring anything to the front of a mix if need be. of course it works exceptionally well for smashing in parallel also. thank you UA for going native with single perpetual licenses. keep adding more product to the list.

Great comp!

Combined with the LA-2A, you can't go wrong!

Love them

The new addition of a mix dial makes these even better and they were already the best.

Great plugin, does what it's supposed to do.

This is an easy-to-use, great-sounding plugin that does exactly what it's supposed to do. It's a must-have compressor, and is super versatile, as it should be. I would definitely recommend.

If I could only have one plug-in to use for the rest of time it's the blue stripe 1176 and it isn't even close.

Amazing sound, the best simulation of 1176's out there

On every channel

I use this as the first compressor on each channel - it adds up to fullness and loudness

The best of the best

Why did avoid UAD for so long? I guess I was using other interfaces and heard they UAD stuff would eat your processor without an external DSP chassis. Stupid mistake on my part because these emulations are incredible. They’re easy to tweak and very inspiring sonically. I have many 1176 emulations and use rack units all the time. UAD versions are the very best I’ve used.

E' il compressore che utilizzo di piu', non fa rimpiangere l'HW!

1176 Incomparable tool

Honestly, there is no tool similar to 1176 Classic Limiter Collection. I've used everything, with all due respect, but other emulations are far from UAD.

Very good compressors <3

I love the 1176 legacy <3

Can't mix without these.

Incredibly versatile plugins for compression, limiting, effects, everything. These 3 are on every single mix I make (mostly the Rev A and E, but AE occasionally). The default settings are a great starting point (except maybe not perfectly unity gain), but knowing how to dial it in pays off. These sound significantly better than any competing counterparts, and I own quite a few 1176 plugins from other companies.

Rev A all day bbbbbbbbb, these 1176 blow others awayyyyy

love these compressors

Having the choice between all of these great emulations is awesome. love the blue face on vocals, really good at adding some nice harmonic distortion. they sound great when pushed, like the originals. love the black one on bass gtr. and the purple-ish
/ black one seems to sound good on everything.

Just updated from the legacy

Loving em so far!
Wish you could switch between them in one plugin, that'd be pretty sweet.
