A refresh for a legendary solid-state electro‑optical compressor.

If you took the gentle optical compression of the Teletronix LA‑2A, and fused it with the solid‑state clarity and punch of the UA 1176, you would have the Teletronix LA-3A — a "secret weapon" compressor with a unique character capable of moving sounds right to the front of your speakers.

Now featuring improved user interface graphics and sonic appointments, the refreshed Teletronix LA‑3A Audio Leveler for UAD hardware and Apollo interfaces takes its rightful place alongside the pillars of classic compression hardware.

Easily shape signals with the definitive solid‑state optical compressor

Add energy and harmonics to vocals and acoustic guitars

Make snare drums pop out of the mix

Add grit and texture to bass guitar and soft synths

Sculpt your sounds further with new HF Emphasis sidechain filter and parallel Dry/Wet Mix

Mix with artist presets from Mark Needham (Imagine Dragons, Fleetwood Mac), Damian Taylor (Björk, The Prodigy), and Eric J Dubowsky (Flume, Odesza) and more

LA-3A History

LA-3A History

The Teletronix LA‑3A Audio Leveler made its debut at the 1969 NY AES show, and marked the departure from the tube design of the Teletronix LA‑2A. The LA‑3A incorporated components and design concepts from UA's solid-state driven 1176LN Limiting Amplifier, while also harnessing the LA‑2A's optical compression design, giving the LA‑3A its own distinctive sound and expanded versatility.

Faithfully Capturing a Classic

Faithfully Capturing a Classic

Immediately embraced as a studio workhorse, the LA‑3A is still widely used today. Engineers and producers the world over favor the LA‑3A for its unique compression characteristics and sonic signature. Modeled from a unit in UA’s vintage collection, the Teletronix LA‑3A Audio Leveler plug-in faithfully captures the rare hardware, working magic on vocals, guitars, and even drums.

New Modern Features

New Modern Features

By adding the hardware’s original HF Emphasis sidechain filter, you can now easily use the Teletronix LA‑3A plug-in to punch up your drum bus without triggering the threshold of the compressor with the kick drum. Plus, a new Dry/Wet Mix control lets you easily add parallel compression on an instrument bus, allowing you to season your productions with legendary Teletronix LA‑3A attitude.

As it says on the tin!

Amazing tool for levelling out peaks and troffs. Another excellent emulation and a key tool for tracking and mixing.

Just like the pro’s told me!

The pros said the LA-3A works great on electric guitars. They were absolutely right. Not sure why I took so long to purchase this unit. Don’t waste your time with other compressors for electric or acoustic guitars. Get yourself one today!

very transparent and usefull -

a lot of times I want to use copm/limiter and regret due to the additional characteristics that influence the sound 2 much. the L3A is like looking in a mirror. WYSIWYG with additional soft warmth.

The advantage is that there is no color.

"Compression without color" can be easily used for various tracks while having a sense of saturation. The advantage is that there is no color.
LA-3A has a natural compression and does not change the balance of each instrument or the mutual groove relationship.
Compared to that, the LA-2A has an impressive sound of the tube, so the track used is conspicuous. We both want to have.

Ah! That Tone!

Worked like magic immediately I placed it onto my vocal chain, everything just came alive. Since then it's been set as a default plugin on my console. Oh! And the presets are also awesome. Combined with the Neve 1073 and the Struder Tape plugins... 7th Heaven!

Good, but not a 3A

First and foremost I love UA and get lots of mileage out of all their plugins including this one. I also appreciate the recent update with retina support and additional features ! With that being Im not sure why UA decided to model such an uncommon "golden unit" for this plugin. Compared to my OG 3A as well as a pair of DIY 3A clones the modeled T4 attack time is MUCH faster giving it a character I dont commonly associate with the 3A. (plugin is ~1.5ms while my hardware and other 3A plugins sit ~30ms) Is the plugin still useful? of course! But Id greatly appreciate the option to switch between both attack times

a thing of beauty

So many compressors, but this one is so smooth (and simple to use), and it doesn't alter the tone as much as some others do.

Super Great All Round Comp!

This was a recent add for me and its been really great. It's super musical just like an la2a is concerned but seems to be a bit more subtle. I am a huge fan!
