Universal Audio LA-2A Classic Leveling Amplifier
True to the original design, UA's recreation of the famed Teletronix®, tube-amplified, T4, electro-optical classic compressor. Handmade in the USA..

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
  • Record your tracks through vintage UA, "handmade in the USA," circuits
  • Track and mix with a piece of audio recording history

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 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.

It’s very hard to go wrong with an LA-2A. It just has that sound. - Peter Katis(The National, Interpol, Jónsi)
