Universal Audio LA2A Classic Leveling Amplifier

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 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. 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 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 c
