Story

True to the original design, UA’s famed tube-amplified T4 electro-optical compressor. 

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.

Dial-in legendary optical tube compression textures for vocals, bass, drums, and more. Easily add iconic warmth and tube limiting with simple, easy-to-use controls. Track and mix with a piece of audio recording 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 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’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. Synth Palace’s LA-2A has been modified to have UTC transformers as used in the original Teletronix, to give you the best of all possible worlds.
