Zähl Elektronik-Tontechnik is a German pro audio manufacturer based in Bergisch Gladbach, founded by engineer Michael Zähl, whose work in analog audio design dates back several decades. Before launching the current product line, Michael Zähl designed and built the custom mixing console for Conny Plank's studio and the console for Can's studio, the latter of which is preserved at the Rock'n Popmuseum in Gronau.

Since 2012 the company has focused on the AM1, a fully analog, modular mixing console that is built to order and configured to each customer's requirements. Around the AM1 sits a broader catalog of analog outboard and monitoring gear, including the EQ1 stereo equalizer, the IM1 M/S Insert Master, the Rack 500 dual 500-series chassis, the HM1 reference headphones mixing amplifier, the H1 reference headphones amplifier, and broadcast intercom systems.

Zähl designs and manufactures its equipment entirely in Germany in low volumes, with circuitry described by the company as consistently analog but not intended as a vintage-style revival. The products are aimed at professional recording, mixing, and mastering studios, and the company also undertakes special custom designs.

Zähl has 3 products cataloged on Equipboard, including Mixers, Effects Processors, and Preamps. Their gear is featured by 3 artists, with the strongest followings in Electronic and Rock. Notable users include Alessandro Cortini, Ricardo Villalobos, and Calibre.
