1176LN Classic Limiting Amplifier
Legendary FET compression with tone and attitude — true to the original.
Upon its release in 1967, the 1176 Limiting Amplifier became an instant classic because of its unique lightning-fast attack and release times, musical Class A output stage, and its wide range of sounds, ranging from subtle, near-transparent compression, to all-out drive and distortion.
Universal Audio’s 1176LN Classic Limiting Amplifier is a handbuilt, faithful reproduction of Bill Putnam Sr.’s original visionary design — an iconic piece of audio history that had a hand behind classic recordings from Led Zeppelin, The Rolling Stones, Michael Jackson, and more.
Now You Can:
Track and mix with the legendary FET-Style Compressor with custom-made class A output transformers
Record your tracks through vintage UA, "handmade in the USA," circuits
Harness ultra-fast attack time on bass, guitars, vocals and more
Add color, character, and and vibe to signals without using compression
A Toneful, Colorful Compressor
Billed as a “true peak limiter with all transistor circuitry and superior performance on all types of program material," the 1176’s major selling point was its ultra-fast attack time — a mere 20 µS (.00002 seconds) at its fastest setting. But engineers soon found out that the 1176 also injected character, attitude, and vibe to anything run through its circuitry. Some even used the 1176 with the compression turned off, just for the distinctive tone it imparts. The unit’s amplifiers and transformers all by themselves give a desirable “hot” quality to anything passing through them.
Rebirth of a Legend
In 1999, when Bill Putnam, Jr. relaunched Universal Audio, a reproduction of the Blackface 1176LN was the company’s first product. Reissued in 2000, it was based on the circuit designs of the C, D, and E revs of the classic 1176. One of the most critical aspects of recreating the sound of the original hardware, was faithfully reproducing the original output transformer, complete with the additional windings that provided the feedback signal to the final line output amplifier circuit. Bill Putnam Jr. found extensive design notes that enabled him to recreate and improve his father’s original design.
One of the 1176’s famous features are its push-button selectable ratios of 4:1 and 8:1 for compression, and 12:1 and 20:1 for limiting. 1176 at 4:1, to its most notable setting, the “All Buttons In” mode, where all the ratio buttons are depressed simultaneously. This allows the 1176 to make a sound unlike any other processor ever heard before. Distortion increases, along with a plateaued slope and a lag time in response to initial transients, creating an explosive sound on drum room mics, fuzzing-out bass or electric guitar sound, or squeezing a vocal to bring it front and center of your mix.
Accept No Substitutes
Carefully trained Universal Audio staff hand build and test each unit until it meets our uncompromising standards. This Universal Audio Classic version of the 1176LN captures all the nuance of the original through obsessive attention to detail and delivers that trademark sound. Demand the original.
“I use my 1176 Limiting Amplifier on everything from bass to vocals to snare drums.”

Universal Audio 1176 LN compressor

Ease of use
Bang for buck (slightly overpriced)
Universal Audio 1176 LN (low noise) compressor
The compressor has a field effect transistor (FET) that uses as a voltage-controlled variable resistor as oppose to a opto, or VCA type compressor. The ratio options are 4:1, 8:1, 12:1, or 20:1. You also have the option of pressing combinations of buttons to provided different responses as well.
There have been many revisions of the 1176 since it came out. Model C included a low-noise circuitry which later in Model D

I own a 6176, an LA2A (all amazing pieces of gear) but the 1176 is my all time favorite UAD product. It just works every time. It delivers punchy vocals for rock and I can drive it super hard, yet it's always musical.
A true classic!
My Favorite Compressor/Limiter of ALL!
I do own the Vintage Silverface UREI Blue Badged Red Off Button Version - which I find is particularly good on soft ballad vocals....
It is my favorite SWEET Limiter & is also good as an Over-Compressed sound effect on Drums etc...
Awesome on Electric Bass Guitar & Soft Ballad Vocals with a Low Comp Ratio & awesome sound just through the box even with Compresor OFF.
I don't like Compressors much anymore except as an effect or light dynamics controller or over-compressed effect - But I LOVE this COMP/LIM & I couldn't live without it! One of the best investments I have ever made... ;-)
Thank you Universal!

a ture classic
The 1176LN is indeed a true classic. The special "british" settings where you'd push more than one ratio button at a time are definitely the highlight of this device, since I have the strong feeling that no software solution comes cloes to this particular sound. It's not that standard drum destroyer thing - that can be done with a Valley People Dynamite much more efficiently. But if you want to get more depth out of crunch guitars, more consistency from drum room mics or simply more level and punch from lead vocals, nothing comes close to a real 1176! Only drawback on my unit: it seems to have an electrical issue - sometimes audio simply stops passing through I had it at a repair shop two times already, they couldn't find the culprit yet... Sad, since UA is known for good build quality otherwise... Hoping for a solution in the near future... One last word: 1176 are not everybodys darling. Eighter you love it or you can't get a good sound from them. I love it!
1176, what else??
UA write me for a review of this unit...
Ehi guy, this is a 1176....One of the Compressor with the "C".
Is a wonderful unit.......what else?
Radio ready for vocals
The ua plugins of this version are really nice and very useful, but once you hear the real deal trust me you'll see why the hype of this specific and legendary piece of gear. Buy one if you have a pro studio set up dont waste your money if you only have a computer and two monitors!
This is my first piece of analog gear. It truly is a wonderful addition to my studio. Sweet sound!
Been lookimg for this all my life!!!
Like the title says.... as soon as I ran some audio through this baby I just new I found the last piece of my puzzle. Been producing at home for 20Yrs and I can't believe its taken me this long to try one. Recommend Recommend!!
