The 2A-KT draws inspiration from the original Teletronix LA-2A leveling amplifier, which was first produced in the early 1960s. Since then, Teletronix leveling amplifiers have been prized for their smooth musical sound, and audio engineers have utilised them at all stages of the recording process – from tracking to mastering.
At the heart of the 2A-KT is a vintage lag-free optical attenuator based on the very same electroluminescent technology used in its predecessor. The 2A-KT is constructed from the highest-quality discrete components – all of which meet or exceed the LA-2A’s original specifications. This is just one of the many ways the 2A-KT brings unparalleled precision and superb signal integrity into the new audio age.
2A-KT owes its characteristic warmth to a set of premium, hand-selected 12AX7, 12BH7 and EL84 tubes. This time-tested combination provides ultra low-noise analog output with the ideal balance of tight, warm bass, silky-smooth midrange and brilliant, airy treble.
