Klark Teknik EQP-KT Classic Tube Equalizer

The Klark Teknik EQP-KT Classic Tube Equalizer is amazingly affordable – and designed for the 21st Century. Mastering quality equalisation, at a price point that makes the Klark Teknik EQP-KT equally at home in your studio – and your live rack!

The Klark Teknik EQP-KT Classic Tube Equalizer is a single-channel, two-band equalizer based on the classic Pultec EQP-1A, featuring Class A, all discrete circuitry for highest signal integrity. With switchable frequency selection, variable bandwidth and custom-built MIDAS transformers, the EQP-KT offers high-quality audio reproduction. If ever there is an official “Audio Technology Hall of Fame”, it will definitely include a shrine to the legendary Pultec EQP-1A. The Klark Teknik pay homage to this audio-processing pioneer that has graced so many recordings, with their Klark Teknik EQP-KT Classic Tube Equaliser.

Building on a Classic
The Klark Teknik EQP-KT draws inspiration from the legendary Pultec EQP-1A equaliser, which was first produced in the early 1950s. Since then, Pultec equalisers 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.

A Class Act
At the heart of the Klark Teknik EQP-KT is a vintage Class-A circuit design constructed from the highest-quality discrete components – all of which meet or exceed the Pultec EQP-1A's original specifications. This is just one of the many ways the Klark Teknik EQP-KT brings unparalleled precision and superb signal integrity into the new audio age.

The Warm Sound of Tubes
The Klark Teknik EQP-KT owes its characteristic warmth to a set of premium, hand-selected 12AX7 and 12AU7 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.

Incredible Flexibility
The Klark Teknik EQP-KT provides the kind of tone-sculpting flexibility that you simply won't find on the average equaliser, such as the ability to boost and cut specific frequency content simultaneously. This functionality is a product of the Klark Teknik EQP-KT's two-band design, which allows the boost and cut controls to work independently of one another – for incredibly flexible shelving. Both the LF Boost/Cut and HF Boost controls provide 7 frequency selections, along with a variable broad-bandwidth midrange control. Finally, the Klark Teknik EQP-KT's HF Cut control lets you dial in the perfect amount of “air” to add a touch of finesse to your top-end content.
