Tegeler Audio Raumzeitmaschine

The Tegeler Audio Raumzeitmaschine is a hybrid tube reverb processor that pairs a digital reverb engine with an all-analog signal path built around two double triodes and input/output transformers per channel, producing spatial reverberation that is transparent and natural while retaining the harmonic character of tube and transformer circuitry. Four primary controls—pre-delay, room size, density, and decay time—give direct, musical access to the reverb sound without navigating large parameter sets, and servomotor-driven controls sync bidirectionally with the companion DAW plugin (VST, AU, AAX) for complete session recall through standard DAW preset management. All connections are analog XLR transformer-balanced, and Ethernet replaces USB for remote control, eliminating cable-length constraints and enabling wireless operation via a standard network router. For Los Angeles mixing and mastering engineers looking for a hardware reverb with a spatial character distinct from purely digital processors, the Raumzeitmaschine is built to serve as a primary stereo reverb across natural room emulations and creative, unconventional spaces alike.

Key Features

• Hybrid digital-analog architecture — a digital processor handles reverb calculation while the signal passes through two double triodes and input/output transformers per channel, adding the harmonic density and spatial character that differentiates the Raumzeitmaschine from purely digital reverb hardware.
• Streamlined four-parameter interface — pre-delay, room size, density, and decay time are the only controls needed to dial in the reverb sound, making adjustments fast and intuitive. The operating approach is intentionally instrument-like rather than menu-driven.
• Input stage overdrive — driving the input stage harder pushes the tube circuit into saturation, allowing a warmer, fuller reverb character when the source material calls for it.
• Servomotor-driven potentiometers with full bidirectional sync — all controls are motorized and sync in both directions: moving a pot on the front panel updates the plugin, and adjusting the plugin moves the physical control. Direct front-panel changes always take priority via a slip-clutch mechanism.
• DAW plugin with session recall (VST, AU, AAX) — there is no preset management built into the device itself; instead, the Raumzeitmaschine relies on the DAW’s native preset and session management, simplifying the workflow and keeping settings tied directly to each project.
• Ethernet connectivity for remote control — the Raumzeitmaschine connects via Ethernet, with no USB cable-length limitations. It can be controlled from the device’s internal web server, the DAW plugin, or wirelessly via a standard network router from anywhere on the network.
• Wide reverb range — natural to unconventional — while designed around natural-sounding spatial reproduction, the Raumzeitmaschine is equally capable of producing highly unnatural spaces—extended decay times, unusual room geometries—making it useful as a creative effect as well as a transparent ambience tool.
• True stereo, transformer-balanced XLR inputs and outputs — all I/O is analog, transformer-balanced, and handled via XLR, with a maximum input level of +22 dBu and dynamic range of ≥110 dB.
