Klark Teknik is a British professional audio manufacturer founded in 1974 by brothers Terence and Phillip Clarke in Kidderminster, Worcestershire. The company built its reputation on signal processing equipment for live sound and studio use, with the DN360 dual-channel 30-band graphic equaliser becoming an industry standard fixture in touring racks and front-of-house systems worldwide. The DN780 digital reverberator, introduced in the 1980s, similarly became a go-to outboard processor in broadcast and recording facilities.

The company expanded through acquisitions of mixing console maker DDA in 1986 and Midas Audio Systems in 1987, before being sold to Mark IV Audio in 1992. In 2009, Klark Teknik was acquired by the Music Group (now Music Tribe), the parent company of Behringer and Midas, and the brand was repositioned to produce a wider catalog including digital signal processors, DI boxes, microphone preamps, and analog-modeled studio outboard such as the 76-KT FET compressor inspired by the classic 1176 design.

Klark Teknik's product range spans graphic and parametric equalisers, dynamics processors, digital snake systems, and the DN100 active DI box, with gear used across live concert touring, broadcast facilities, houses of worship, and recording studios. The brand is most closely associated with rugged British-engineered EQ and dynamics hardware aimed at professional sound reinforcement applications.

Klark Teknik has 23 products cataloged on Equipboard, including Effects Processors, Direct Boxes, and Preamps. Their gear is featured by 17 artists, with the strongest followings in Electronic, Pop, and Rock. Notable users include Kevin Parker, Aphex Twin, and Dijon. Most Klark Teknik products fall in the mid-tier range — professional-grade without flagship pricing.
