Klark Teknik 2A-KT Optical Tube Leveling Amplifier

Inspired by the mother of all optical compressors, Klark Teknik set the bar high for its 2A-KT Leveling Amplifier. With its warm, musical sound and flexible, highly effective dynamics control, the Klark Teknik 2A-KT Optical Tube Leveling Amplifier is eminently useful in live settings and in all stages of the recording process, from tracking to mixing to mastering. The beating heart of the 2A-KT is a vintage-style no-lag optical attenuator based on the same electroluminescent technology employed in its 1960s predecessor. The 2A-KT is built using high-quality discrete components – all of which meet or exceed the specifications of the legendary compressor it is based on. Its characteristic warmth comes courtesy of hand-selected premium 12AX7, 12BH7, and EL84 tubes in a circuit that delivers ultra-low-noise output with tight bass, liquid midrange, and delicate, airy treble.
