Tegeler Audio Manufaktur is a Berlin-based manufacturer of hand-built analog studio hardware, founded by developer and former sound engineer Michael Krusch in the Tegel neighborhood in the north of the city. The company builds its devices around tubes, transformers, and discrete components, drawing on the aesthetics of classic broadcast and mastering gear while developing its own circuits and control schemes rather than cloning vintage designs outright.

The catalog centers on processors aimed at tracking, mixing, and mastering engineers, including the Schwerkraftmaschine remote-controllable Vari-Mu bus and mastering compressor, the Creme stereo bus compressor and passive mastering EQ, the Raumzeitmaschine tube reverb, the Vari Tube Recording Channel strip, the Classic EQP-1 equalizer, the Magnetismus 2 tape-style saturator, the Tube Summing Mixer, and the Konnektor analog mastering matrix. Units are assembled and tested in the company's Berlin workshop and adjoining studio, with many models offering recall via software for integration into modern DAW-based production.

Tegeler has 9 products cataloged on Equipboard, including Effects Processors, Channel Strips, and Mixers. Their gear is featured by 5 artists, with the strongest followings in Electronic, Rock, and Folk, World, & Country. Notable users include NIVIRO, Paul Davids, and Robert Babicz.
