Universal Audio Teletronix LA-2A Leveling AmpTrue to the original design, UA’s famed tube-amplified T4 electro-optical compressor.

For over 50 years the Universal Audio Teletronix LA-2A Leveling Amp 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.

Now You Can:

• Dial-in legendary optical tube compression textures for vocals, bass, drums, and more.
• Record your tracks through vintage UA, “handmade in the USA,” circuits.
• Easily add iconic warmth and tube limiting with simple, easy-to-use controls.
• Track and mix with a piece of audio recording history.

The Teletronix Story

Teletronix founder Jim Lawrence first used photocells to control 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 Teletronix LA-2A Leveling Amp reissue provides the performance characteristics of the iconic original. With painstaking care, every new LA-2A unit is point-to-point hand-wired in Scotts Valley, 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.
