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.

The Real Deal

Universal Audio’s Teletronix LA-2A Classic Leveling Amplifier reissue provides the performance characteristics of the iconic original. With painstaking care, every new LA-2A unit is point-to-point handwired at Universal Audio's Custom Shop in Santa Cruz, California, with every component carefully evaluated for authenticity. As a result, today’s LA-2A will bring the same legendary compression characteristics of the original to all of your recordings. Demand the original. Accept no copy.

I’ve never used the real Analog version

How is this plugin free with the Apollo units? Well I’m glad it is . This plugin alone is well worth the price of all Apollo interfaces. Buttery smooth sound on my voice over recordings.

Simply the best!

It is hard to make things so bad with the LA-2A. The tone and level control of this unit is just superb.

LA-2A for EU-Market?

How can a unit, any kind of unit, turn a good sound into a better sound? To me it is not logic, but I have to admit, the LA-2A d o e s a marvellous job, even at spoken text.
I use Neumann U67, Telefunken V72, then LA-2A - no questions left, no drive to search for any other solution.

Big question: Why isn't the LA-2A available in Europe?
Why not offer a 220 Volt version, straight forward to the EU-Market?

Teletronics LA-2A

This compressor is one of the Best things I use every time when I record Vocals. Also this piece comes handy for Bass or Guitar while mixing them up. Yeah it’s easy to understand how it works. I also tested this particular one with Waves emulation and I have to say that UAD version has some kind of analog flavour on it, so for me this is the Best weapon out there ;-)

The most amazing gear in my rack!

Even though it is the new and not the vintage version (I heard so much about referencing the versions..) it's still blows my mind and adds an amazing sub harmonic magic to every channel you're putting it on. since I got it it's my vocals, bass tracking go-to.. (chained after my 1176 compressor)
always the right choice for my mixes as well.. can work almost on anything. pure joy

There is nothing to improve on an already perfect design...

The LA2A is plain magic. Just try to compress a voiceover with a low male voice, and compare the hardware vs. any software modelling solution. You'll see... Same goes to electric bass... And if anybody tells yoou that optos are not for drums, try it on bassdrum just once, and the judge on your own!

I'll say it a million times.

This is the plug you want to get out the gate when you start UAD. It's utility. Between this and the Fairchild are $. The others are as well but this will truly show you the epitome of UAD sound and power. Just a magical little plug

It ain't the same without the LA2A!

This vintage limiter/compressor is by far the best around. The way way the vocals. Sound so warm and the way they melt on a record is Extra ordinary, I run my neaumann mic thru my Avalon 737 to he LA2a and the results are very impressive . I don't think I could ever record anything with out it. I adds that extra element to every recording it's a must buy if you want that radio sound and clarity .

I can't imagine recording a voice without that compressor. I used it with a preamp neve 1272 and a sony c800g microphone...what else ?!

The best ever !!!!

I have used this compressor in many studios and in all kinds of stiles all over the years, but only now I had the chance to by one of my own an I have no words to describe how happy I am.
One thing is more than clear, I won't sleep tonight. lol

Beautiful

Ive only ever used one hardware LA2A in my life, that is the new RI i bought last week.
The sound is amazingly lush and rich, the distortion on some sources just makes you melt.
The new LA2A plugin pack is fabulous, but as they say; close but no cigar.

I love this compressor, its beautifully made also and feels like a tank.

I use it for guitars mainly, but also some percussion, pretty much everything i send it comes back better.
LOVE IT LOVE IT LOVE IT!
