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. In 2001, Universal Audio set the standard in analog emulation with the original UAD LA-2A plug-in.

Today, UA's engineers have redesigned the LA-2A plug-in with more obsessive detail. The LA-2A Classic Leveler Plug-In Collection features immaculate models of three highly sought-after LA-2A units, giving you the most authentic emulations ever of this iconic compressor.

Native and Apollo Realtime/UAD‑2 Versions Included -- No UA Hardware Required

UAD Teletronix LA-2A Leveler Collection runs natively on your macOS or Windows computer, or accelerated on systems with an Apollo audio interface, UAD-2 Satellite, or UAD-2 PCIe card.

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

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… read more 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.
