Teletronix® LA-2A Classic Leveler Plug-In Collection Trailer

The Ultimate Software Collection of the Most Revered Optical Compressors in History.

The Teletronix LA-2A Leveling Amplifier rivals only the Universal Audio 1176 as one of the most revered compressors ever created. With its gentle, program dependent optical compression and meticulously designed tube amplifier, the LA-2A is the go-to compressor for professional mixers around the world — especially for vocals.
 
In 2001, Universal Audio set the standard in analog emulation with the original UAD LA-2A plug-in. Since then, advances in processing power and a decade of analog emulation experience enabled UA’s engineers to redesign the legendary LA-2A with luxurious, obsessive detail. For the new LA-2A Classic Leveler Plug-In Collection, Universal Audio painstakingly modeled the entire electronic path of three of the most sought-after LA-2A units — “Silver,” “Gray,” and the original LA-2 model – creating the most authentic emulations ever of this iconic compressor.

History
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 tube detector circuits. Universal Audio founder M.T. ”Bill” Putnam later purchased this patented technology, continuing to manufacture the LA-2A for years to come.
 
Universal Audio still hand-builds the original LA-2A hardware to this day at our headquarters in Scotts Valley, California. Decades of experience manufacturing these units provides UA with unique, in-depth understanding of the complex interactions of the LA-2A — particularly its unique T4 photoresistor and luminescent light source behaviors. The result is easily the world’s most accurate DSP model of the LA-2A as a UAD plug-in, right down to its transformers, amplifiers, and distinctive photo cells.

Three Historical Units
The Teletronix LA-2A Leveler Collection puts three of the most coveted incarnations of the iconic Teletronix processor at your fingertips. As with 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
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 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.
