Schwerkraftmaschine
Remote Controllable Vari-Mu Mastering and Bus Compressor

The master of mastering

We have spent so much time planning, constructing, testing, programming, checking… and above all else, listening.
This product incorporates the sum of all our expertise, combined with the feedback we got on the VTC.

The result is a Vari-Mu compressor without equal. “The Compressor.”

We are proud of the result and are delighted to be able to put a tool in your hand that will make your music sound even better.

How the Schwerkraftmachine polishes sound to perfection

In the Schwerkraftmaschine, the signal passes through a total of three transformers and four triode tubes per channel.

Why does this matter? Tubes, and especially triodes, add harmonic overtones to the signal that the human ear finds pleasing, while improving our perception of individual sounds.
The individual instruments are given additional presence through the tubes.
Through the conversion of electricity into magnetic fields and back to electricity, the transformers and their non-linearities increase the density of the sound before it is compressed.
The bass becomes cleaner and more defined. The high frequencies are pleasantly rounded.

The Schwerkraftmaschine makes the difference between “well mixed” and “sounds perfect”.

Compression modes

Whether it is about softly compressing the sound, a more harder effect, or responding to complex situations…
There is a program for everything.

Generating a digital control signal offers flexibility that simply cannot be found in analogue equipment.
This makes it possible to emulate the behaviour of any existing compressor.

When you need the Schwerkraftmaschine to work like anOptical Compressor, including the memory effect?

But with the Attack and Release still being adjustable?
It’s a piece of cake!

Or you need it soft like a Vari-Mu? Or preferably just like a VCA?

Tasks like this are child’s play for the Schwerkraftmaschine.
We have created completely unique programs that have previously never existed in any compressor, which generates the control signal based on complex rules.

We have created and optimised this equipment through countless listening sessions.
Just choose the right program for the each song.

The motor control

Every control is fitted with a servomotor which can set the pots into any position.
You can make adjustments whenever you want – a slip clutch combined with software always gives your direct control the priority.

Do you need all these modern network based tools? No, not at all!
The Schwerkraftmaschine can be completely controlled from the front panel, where it behaves like any other piece of hardware.

The side-chain filter

The side-chain filter determines which frequency range the compressor responds to.

Prevent pumps using the low-cut filter.

Add weight to the high or low frequencies using the pitch filter / tilt EQ.

The sidechain filter works separately to the built-in compression mode filters.

The Plug-In

Download the plug-in to your favourite DAW and control the Schwerkraftmaschine via the plug-in. The motorised pots follows every movement.

Or directly on the device itself. Both settings are synchronised.

When you save your song with the plug-in, the settings are automatically saved in the Schwerkraftmaschine, too. When you reload the song, all your settings are back. All the controls are exactly as they were before.

Dual mono mode

The plugin allows the Schwerkraftmaschine to be split into two separate mono channels.

Both channels then operate independently of each other. This means that two separate tracks can be processed individualy.
All controls can be set separately for the left and right channel.
The only thing they have in common is that channels always use the same mode. And the stereo transformer mode is not useful in dual mono mode.

Together with an LR/MS and MS/LR matrix, the Schwerkraftmaschine is also ideal for M/S compression.

As the physical front panel cannot be duplicated, this mode cannot be controlled directly on the device, but only via a plugin.

For audio professionals and enthusiasts seeking unparalleled sound clarity and control, the Tegeler Audio Schwerkraftmaschine amplifier offers a precision-engineered solution that elevates your audio production experience. In a world where every nuance of sound matters, this amplifier ensures that your signal remains clean, dynamic, and true to the original source, enabling you to craft mixes and recordings with exceptional fidelity.

The core appeal of the Schwerkraftmaschine lies in its ability to handle a wide frequency range from 20 Hz to 24 kHz, covering the full spectrum of human hearing and beyond. This means that whether you are working with deep bass tones or sparkling high frequencies, the amplifier reproduces every detail without distortion or loss. With a maximum input level of +20 dBu and a maximum output level of +24 dBu, it accommodates high-level signals without clipping, providing headroom that keeps your audio transparent and free from unwanted saturation.

Input impedance of 2.4 kΩ or higher ensures compatibility with a variety of professional audio sources, minimizing signal loss and preserving the integrity of your sound. The low output impedance of less than 600 Ω further guarantees optimal signal transfer to downstream devices, resulting in a clean and stable connection that maintains audio quality throughout your signal chain. This is critical for professionals who demand consistency and reliability in their gear.

Dynamic range is another standout feature, with a specification of at least 101 dB. This wide dynamic range allows the amplifier to reproduce the quietest details and the loudest peaks with equal precision, giving your audio a natural and lifelike presence. The amplifier operates efficiently on a voltage range of 110 to 240 volts at 50-60 Hz, making it compatible with international power standards, while its maximum power consumption remains under 25 watts, ensuring an energy-efficient performance that won’t add unnecessary heat or noise to your studio environment.

Physically, the Schwerkraftmaschine is designed with practicality in mind. It occupies 3 U of rack space, measuring 132 mm in height, 483 mm in width, and 250 mm in depth, making it a compact yet substantial addition to any professional rack setup. The inclusion of a 2 A slow-blow fuse provides protection against power surges, contributing to the longevity and reliability of the unit. Its build quality reflects Tegeler Audio’s commitment to robust, precision-engineered components that stand the test of time.

This amplifier is ideal for use in recording studios, broadcast facilities, and live sound environments where accuracy and reliability are paramount. Whether you are amplifying signals from microphones, instruments, or other audio gear, the Schwerkraftmaschine’s transparent amplification ensures that the character of your source is preserved, allowing you to make critical mixing and mastering decisions with confidence. It’s also well-suited for audiophiles who demand the best in home audio systems.
