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.
