Recording equipment · United States

The Teletronix LA-2A is a tube-based optical leveling amplifier that uses an electro-optical attenuator, a photocell paired with a light source, for program-dependent gain reduction. Its smooth, frequency-dependent compression made it a studio standard for vocals and bass and one of the most widely emulated compressors.
