Get UA’s Famed Optical Tube Compressor, True to the Original Design
For over 50 years the Teletronix LA-2A has been revered for its smooth, natural, musical compression. WIth its unique tube-driven electro-optical attenuator system that allows instantaneous gain reduction with no increase in harmonic distortion, the LA-2A massages signals like no other compressor ever made.
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.
Explore 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.
