TK Audio is a Swedish manufacturer of analog outboard audio equipment based in Halmstad, on Sweden's southwest coast. The company was founded in 2008 by electronics engineer Thomas 'TK' Kristiansson as a sister brand to his earlier Vintagedesign line, with design, assembly, and testing handled in-house at their Halmstad facility.

The brand is best known for the BC1 stereo bus compressor, a VCA design inspired by the classic SSL bus compressor topology and notable for introducing an easily accessible dry/wet parallel-compression blend control. The BC1 has been released in several revisions, including the BC1 MkII, BC1 Ltd, BC1-S, and BC1-THD. The product range also includes the T-Komp FET compressor, the TEQ equalizer, the DP3 dual processor, the M/S Station mid-side tool, and the Transceiver 2 reamp/DI unit, along with 500-series versions such as the T-Komp 500, BC501-GR, M/S Blender 500, and SP502.

TK Audio's gear is aimed at mixing and mastering engineers working in both studio and live contexts, with a focus on straightforward analog signal processing built in small production runs.

TK Audio has 19 products cataloged on Equipboard, including Effects Processors, Preamps, and Direct Boxes. Their gear is featured by 4 artists, with the strongest followings in Electronic, Pop, and Rock. Notable users include Avicii, Jay Watson, and Flux Pavilion. Most TK Audio products sit firmly in the high-end, boutique range.
