 Audio professionals passionate about their compressors revere the LA-2A. The original was immediately acknowledged for its natural compression characteristics. A unique electro-optical attenuator system allows instantaneous gain reduction with no increase in harmonic distortion – an accomplishment at the time, still appreciated today.
Universal Audio now announces the rebirth of the Teletronix LA-2A, a Universal Audio Classics product. Painstaking care has been taken to ensure that every new LA-2A provides the performance and characteristics of the original. Each unit is hand built, each component carefully evaluated for authenticity. No expense has been spared to guarantee that this LA-2A will bring that classic sound to your recording.

Evolved from the popular Universal Audio 175 and 176 vacuum tube limiters, the 1176LN retained the proven qualities of these industry leaders, and set the standard for all limiters to follow.
Today, the 1176LN is new again. While it certainly would have been possible – and much simpler – to modernize and "improve" the 1176LN, every effort was made to remain faithful to Putnam’s design and intentions. Carefully trained staff hand-wire 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. Accept no copies.

The 2-1176 builds from the circuit design of UA’s hugely successful 6176 Channel Strip and combines two 1176 channels from that unit-- an uncompromising design, with all the same components- stereo matched to boot!
With the release of the 2-1176, we once again put that sound into your rack but with twice the tone, twice the character and twice the compression-- at an unbelievable price, and half the space. As you would expect from UA, it also retains all the features and trademark sound of its ancestor, and switches easily between dual mono and stereo link.
And yes, it does All Buttons In! |
 The 2-LA-2 is not an exact component clone of the classic LA-2A, but a feature-enhanced stereo evolution of its ancestor that elegantly combines two channels of silky, tube-amplified, stereo matched optical gain reduction in one unit.
Like its ancestor, the 2-LA-2 works by applying the audio signal to an electro-luminescent light panel which shines on a photo-electric cell which in turn controls the gain. Designed by original UREI® engineer Dennis Fink, the 2-LA-2 retains the core “sonic signature” components that made the LA-2A the studio standard compressor in recording studios around the world.
The 2-LA-2 uses only the finest audiophile quality parts, from metal film resistors and WIMA capacitors to custom UA input and output transformers. From drum bus to master bus, vocals to vibraphones, the 2-LA-2 delivers the same authentic, smooth as silk gain reduction you’ve come to know and trust with the LA-2A, conveniently re-designed into a 2U two-channel package. |  The original 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 Leveling Amplifier. The LA-3A incorporated components and design concepts from the Putnam-designed 1176LN Limiting Amplifier. Immediately embraced as a studio workhorse and still widely used today, the LA-3A remains a favorite of engineers and producers worldwide for its unique compression characteristics and sonic signature.
Our UA Classics reissue of the LA-3A meticulously retains all the internal and external qualities of the original: The same simple control set, and the T4 electro-optical attenuator, which is the source of the LA-3A’s program dependent compression. It also retains the 2RU half-rack design, and comes complete with a single-unit rack assembly--no additional kit is necessary. All the original rear panel connections and controls are also maintained, while the commonly performed “LA-3A gain mod” is added as an additional switch for maximum studio versatility. |  The original 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 Leveling Amplifier.

 Advances in digital recording technology are providing users with tremendous power and flexibility for increasingly less money. All too often, however, the audio quality of these systems is limited by their input stages. Many users who demand the power and flexibility of today’s recording technology find themselves yearning for the warmth and tone of yesteryear’s hand-built analog circuitry. Now with the release of the 6176, Universal Audio, for the first time, combines their highly acclaimed 610 tube microphone preamp with their legendary 1176LN compressor to create the ultimate single channel signal path for everything from vocals to vibraphones.
610B Mic Pre
The 2-610 microphone and instrument preamplifier has received praise from many corners. Michael Cooper, in his review for Mix Magazine, called it “hands-down, the most dimensional mic preamp I've ever heard…” Peter Wade, engineer/producer who has worked with acts ranging from Wyclef Jean to Jennifer Lopez, said simply, “This box rocks.” The 6176 mic preamp sections maintains the quality and character of the 2-610 while adding high-tension power regulation for improved bass response and a front-panel 15db pad switch.
1176LN Limiting Amplifier
As legendary engineer/producer Andy Johns put it, “The 1176LN is the workhorse compressor.” The 1176LN may well be the most loved compressor in history. Its trademark lightning-quick attack and release times and the tone of it’s Class A output amplifier have enhanced countless recordings over the last thirty-five years. We’ve recreated the 1176LN for the compressor section of the 6176 with the same exacting, attention to detail and tradition we use on our 1176LN. The resulting character, heritage and tone simply cannot be found on other channel strip units.

|  The LA-610 brings UA’s legendary vintage "all tube" luxury sound into a modern channel strip format by combining the 610 Mic-Pre/EQ/DI section and a T4 Opto-compressor into a single 2U unit with a ground-breaking price.
The 610-tube preamp,DI and EQ is from UA's TEC award winning 6176 and is based on the legendary console modules developed by Bill Putnam in the 60's. Countless classics have been recorded using these preamps, noted for their musical character and warmth.
The simple operation and program dependent nature of the LA-610 T4 compressor provides the same extremely musical control that has made the LA-2A such a well-loved classic for over 40 years.
The LA-610 packs tremendous sonic versatility and is an ideal front-end for tracking with modern DAW’s and the serious project studio looking to get the UA sonic experience : real quality and character at an accessible price.
In collaboration with Dennis Fink, one of the original UREI® analog design engineers, the LA-610 was carefully designed to deliver the essence of the “LA” sound but without the costs of being an exact LA-2A component clone. The LA-610 uses three 12AX7A’s, a single 6072A and a single 6AQ5 tube for amplifier warmth and overall tonal balance.
After the preamp section, the LA-610 offers a new T4 optical compressor. The electro-optical detector or "T4 cell”, is the very heart and soul of the Teletronix LA-2A. The unique combination of electroluminescent panel and photo-resistors inside the T4 cell are the crucial circuit components that give both these compressors their signature sound. |
