KLARK TEKNIK 2A-KT OPTICAL TUBE LEVELING AMPLIFIER

Klark Teknik 2A-KT Optical Tube Leveling Amplifier

Tube Optical Leveling Amplifier with Discrete Signal Path, 10Hz-20kHz Frequency Response, Midas Transformers, Pre-emphasis Trim, and Vintage-style VU Metering

Classic Optical Compression for a Song

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 2A-KT 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.

Impressive capabilities

The 2A-KT boasts a truly impressive frequency response of 10Hz to 20kHz (±1dB), and it boasts capabilities you won't find in most vintage-style tube leveling amplifiers, such as gain limiting from 0dB to 30dB with an ultra-fast 10ms attack time, release times that range from 50ms to five seconds, and much more.
