Tube Leveling Amplifier for Studio Use

The Klark Teknik 2A-KT is a tube compressor modeled after the classic Teletronix LA-2A. It uses hand-selected 12AX7, 12BH7 and EL84 tubes in a fully discrete signal path. The optical attenuator is based on original electroluminescent technology for lag-free gain control. Custom Midas input and output transformers complete the analog chain.

Check Rack Space and Power Before Buying

This unit occupies two rack units and requires mains power. Verify that your rack has the depth and free slots to accommodate it. Confirm the voltage selector matches your local supply before connecting. Ensure your patchbay or interface has balanced XLR or TRS connections for the input and output.

Tubes and Transformers Shape the Sound

The premium tube set delivers ultra low-noise analog output with tight bass, smooth midrange and airy treble. The Midas transformers add color and drive that define the unit's character. Together they provide the musical compression behaviour associated with the original 1960 design. No software or digital control is included.
