The Klark Teknik KT-2A is inspired by the legendary Teletronix LA-2A, a tube-based optical compressor first introduced in the early 1960s and notable as the first compressor to use an optical control element rather than a fully tube-based design. Drawing on the strengths of the three original models produced up until 1969, Klark Teknik has recreated their character while incorporating modern components, including parts from Midas, resulting in a unit that captures the classic sound while offering greater reliability. With this approach, the KT-2A presents itself as an appealing choice for cost-conscious producers seeking an authentic hardware alternative to the many software emulations available today.
From the front, the KT-2A closely resembles the original, which also means that it could hardly be easier to operate – just two main controls, output gain and peak reduction, where increasing the reduction applies more compression and the gain is raised to balance the level. A switch allows the mode to be toggled between Limit and Compress, though given the inherently smooth nature of the compressor, the difference is subtler than expected. Beyond that, the front panel houses only the metering controls and a power switch, keeping the design clean and straightforward.
The 2A-KT owes its signature warmth to a carefully chosen set of high-quality tubes – 12AX7, 12BH7, and EL84 – which work together to deliver a low-noise analogue output with a well-balanced sound, featuring tight, warm bass, silky-smooth mids, and bright, airy highs. The tube compressor, with its optical control element, particularly enhances the bass, eliminating the need to manually adjust time constants like attack and release. In three little words, the Klark Teknik 2A-KT's sound is soft, fat, and big.
Founded in 1974 by brothers Terence and Phillip Clarke, Klark Teknik designs and manufactures professional audio equipment used primarily in the events industry. Based in Kidderminster, Worcestershire, UK, the company has developed a number of innovative products in the audio field (including the DN60 Real Time Analyzer and the DN300 Graphic Equalizer) and it won one of the Queen's Awards for Enterprise in 1986. Today, the firm (along with Midas) is owned by the Music Group, to which Behringer also belongs.
The Klark Teknik KT-2A boasts a fully discrete signal path and custom-designed MIDAS input and output transformers, all housed in a robust two-unit-high rack enclosure with durable Neutrik XLR and jack connections on the rear panel. Built to withstand the rigours of stage use as well as studio work, it includes a self-adjusting universal power supply for reliable performance anywhere. For stereo applications, two units can be linked via the Sidechain Out and adjustable stereo link function, allowing stereo signals to benefit from its signature gentle, warm compression.
