Tegeler Audio Schwerkraftmaschine

Welcome to the Gravity Machine

The Tegeler Audio Manufaktur Schwerkraftmaschine ("Gravity Machine") is a premium stereo Vari-Mu tube compressor engineered for mixing and mastering engineers who demand uncompromising analogue tone alongside modern digital recall. Combining a 100% analogue signal path with a digitally calculated sidechain control system, the Schwerkraftmaschine bridges the gap between classic vintage warmth and flexible digital workflows. Whether glued across the mix bus, tracking vocals, or crushing drums, it delivers authoritative dynamic control tailored for professional recording and mastering environments.

Pure Analogue Tube Signal Path
At the core of the Schwerkraftmaschine is a fully analogue circuit incorporating three transformers and four triode tubes (two double triodes) per channel. The transformers build density and low-end definition before dynamic attenuation even begins, while the triode tube topology introduces musical harmonic overtones that enhance instrument separation and depth. High frequencies remain smooth and unforced, giving your tracks an expensive, finished polish without unwanted harshness.

Eleven Compressors in One Unit
Instead of restricting you to a single circuit topology, the Schwerkraftmaschine utilises a DSP-calculated control signal to drive its analogue tube reduction stage. This hybrid design allows the unit to accurately replicate eleven distinct compression behaviours—ranging from smooth Vari-Mu and punchy VCA compression to opto-style levelling and complex multi-band algorithms. Engineers can select the exact dynamic response a track requires without needing a rack full of dedicated hardware.

Motorised Recall and DAW Automation
Equipped with motorised servo potentiometers and an Ethernet network interface, the Schwerkraftmaschine offers total hardware recall directly from your DAW via a dedicated plug-in (VST, VST3, AU, AAX, CLAP). Parameter movements on screen physically turn the front-panel knobs in real time, while session settings are stored within your DAW project for effortless recall. Slip clutches ensure immediate manual override from the front panel whenever physical tweaking is preferred.
