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 an Optical 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 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 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 network connection

Connect the Schwerkraftmaschine to your network. It acquires the settings it needs automatically via DCHP.
You can control the Schwerkraftmaschine from anywhere in the world – be that Sydney, L.A., or even Berlin.

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.

Only the logo is new. Nothing else has changed.

For economic and environmental reasons, we refrained from throwing away everything with the old logo. Instead, we will replace all parts and materials piece by piece. Of course, when you buy a unit, you get the same quality no matter what logo is on the outside.
The device needs a DHCP server to provide it with an IP address.
Simply set up an Internet share for your Mac's network interface.
Go to System Preferences->Shares, select Internet Sharing on the left.
