The Teletronix Story

The Teletronix Story

Teletronix founder Jim Lawrence first used photocells for controlling audio gain in the early 1960s. His ingenious optical compression design was a technological breakthrough, far surpassing the stability and transparency of earlier circuits. Universal Audio founder M.T. ”Bill” Putnam later purchased this patented technology, continuing to manufacture the LA-2A for years to come.

Three Historical Units

Three Historical Units

The Teletronix LA-2A Leveler Collection puts three of the most coveted incarnations of the iconic Teletronix processor at your fingertips. Like the hardware, the LA-2A Silver, LA-2A Gray, and LA-2 models offer distinct variations in time constants, compression knee, headroom, distortion, program and frequency dependence, and more.

LA-2A Silver & Gray

LA-2A Silver & Gray

With a brushed aluminum panel and original T4B gain reduction module, this cherished late-1960s “Silver” version of the LA-2A, manufactured by Bill Putnam, is perhaps the most flexible of the three plug-ins in the collection. Its fast time constant makes it suitable for the widest variety of program material, including transient-rich sources like drums and percussion. Jim Lawrence’s original mid-1960s “Gray” version the LA-2A maintains a more average time constant, providing a range of “medium-speed” compression.

The Original LA-2

The Original LA-2

The exceptionally rare, early 1960s LA-2 unit preceded the LA-2A by several years. It provides the slowest response and a unique “mellowed” sound due to 50 years of luminescent panel aging inside the T4 module. Use the LA-2 with legato tempos and vocal sources for a transparency and sublime mood unlike any other compressor.

This Was A Major Surprise - The LA2 & Pultec Combo

I needed an affordable soundcard for some laptop work outside my main studio, so I opted for the UA Volt 1, the cheapest option available. That turned out to be a great purchase, well worth the price. Along with the soundcard, I received a bundle of free plugins, including the LA2. and the LA2A Gray and Silver compressors and the Pultec EQs. Over the years, I've accumulated numerous plugins, but I don't even install most of them anymore. For the past seven years, my go-to EQ has been Fabfilter, which is functional and does the job. For compression, I usually rely on Ableton's stock plugins simply because all my other comps are no better. I spent years searching for plugins with that elusive "mojo," and I had basically given up and made a decision I wasn't even going to bother downloading the bundle.

But one evening after using the soundcard for about two weeks I thought, OK I will check them out, expecting the usual underwhelming results. Plugins downloaded, fired up a session and to my major surprise, I found myself very quickly impressed. I started applying the LA2A compressors and Pultec EQs on various tracks and very quickly replaced all other comps and Eqs in the session with the LA2s and Pultecs. Just initiating the LA2's without adjusting anything seemed to hit the mark every time - and still does.. The EQ;s I was pushing to max and still track elements sounded good. However, I told my self its just my imagination, after all I've been here many times before and its probably just that placebo effect of thinking something sounds great and the next day I will know its just my imagination. But the next day the session still sounded good, and what I was hearing suspiciously sounded like Mojo. I was beginning to realise the plugins had genuinely helped me improve the sound. The mix had a vibe reminiscent of what I used to achieve with analog consoles, and the compressors added a cool, pumpy quality to the tracks. Even when over pumped, still sounded good - It was just more vibe.

But because years of reality hitting and the ultimate come down I was still thinking this newfound enthusiasm will wear off because that's what always happens. But, that's not what happened. I've continued to use the LA2A and Pultec plugins in every session since. I'm actually enjoying EQ'ing and compressing stuff - Imagine that!. Yes, I also hear that 3D thing others talks about in their reviews.. Coming from someone who had grown jaded with plugins over the years, believe me, this is a significant endorsement.

I don't know what magic the UAD coders have worked, but to me these plugins are very musical and have legit Mojo. And you know what's also great about them - no fancy flashy distracting Guis which force you to mix with eyes. Needless to say the coders have done a 10+ star job. I've never owned the original hardware, but have owned some emulations in the past and these plugins outshine others by all others I have tried or owned by a huge margin. The fact that I got them with a £100 soundcard, which also included a decent Plate Reverb, an Echo (not really my style), a channel strip, and a Synth, is incredible. But its the LA2A and Pultec plugins that are the true stars of the bundle though and its well worth picking up the Volt 1 just to get the plugins.. They are now my absolute and only go to EQ and Comps and only if I need to get very surgical will I fire up the Fab.

The best emulation on market

Having used real LA-2As, I can confidently say this is the best LA2A plugin collection by far

zero stars

terrible customer service, when you buy plugins they don't belong to you at all. If you buy multiple interfaces in particular, you cannot transfer any of the plugins with them unless you completely leave the uad system. the worst. the support is incredibly unfriendly too.

Exceptions can be made

I am a loyal SSL user. 99% of my workflow is SSL complete plugins and a UF8 console. However, there are two plugin bundles that will have a place in every mix for the rest of my days: Pultec EQs and the LA-2A compressor. I'm saving to buy analog modules of both.

I wish I had this collection years ago.

The Teletronix LA-2A Collection has become my go-to for compression. They are super simple to use and they sound great.

It can be easy to go down the rabbit hole of trying to find the best software compressor - I've tried quite a few. And, while many of them are decent, I almost always end up using a Teletronix LA-2A. They just work.

Best ITB LA-2A

Unlike other plugins trying to emulate this hardware, the UAD version is very close. Very smooth. The 3 different revisions all have quite different attack times, meaning this collection is a lot more flexible than it seems with just the two knobs.

Great workhorse for vocal leveling

I purchased the LA-2A Leveler Collection in October 2023 through Plugin Boutique. License registration to my UA account was quick and easy. It's been lovely to have access to sweet, sweet optoelectrical compression. The LA-2A is considered a studio staple with good reason, and UA have delivered a fine set of emulations.

This compressor is a miracle!

I've tried all sorts of 20-knob compressors and finally the LA-2A sounds better again :-) It's been my favorite compressor for decades! The Gray version is my first choice for vocals and piano (usually after another quick compressor). The Silver one I use more for other instruments. And the LA-2 is very special! It's very slow, but if matched with some smoother instrument (synth or pad), the sound becomes amazing!

Great leveling amp.

Had a couple of mixes that sounded good but was just missing something. Ran mixes with the LA-2A leveling amp and boom problem solved.
