Description

Schwerkraftmaschine
Remote Controllable Vari-Mu Mastering and Bus Compressor

Which compressor does this song need?

The vocals ask for an optical compressor. The drums want a VCA. The mix bus likes a gentle Vari-Mu. Usually that decision is made by whatever happens to sit in your rack.

In the Schwerkraftmaschine, the audio runs through a fully analog tube signal path, while the control signal that decides how to compress is calculated digitally. So the same tubes and transformers can follow the rules of an optical compressor on Monday, a VCA on Tuesday, and a program that never existed in any analog circuit on Wednesday. You choose a mode instead of buying another compressor.

This machine carries the sum of everything we have learned, together with all the feedback we received on the VTC. The result is a Vari-Mu compressor without equal. “The Compressor.”

How the Schwerkraftmaschine polishes the sound

In the Schwerkraftmaschine, the signal passes through a total of three transformers and two double triodes 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 gain additional presence through the tubes.
Through the conversion of electricity into magnetic fields and back, the transformers and their non-linearities increase the density of the sound before any compression happens.
The bass becomes cleaner and more defined. The high frequencies are pleasantly rounded.

Only the control signal is digital. The audio path itself stays fully analog from input to output, and that is exactly why a compressor with eleven personalities still sounds like tube hardware.

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

Eleven compressors to choose from

Whether you want to thicken a signal gently, grab it hard, or react to situations no single circuit could handle: there is a program for it.

Generating the control signal digitally offers a flexibility that analog circuits alone cannot reach. It makes it possible to emulate the control behaviour of virtually any existing compressor.

You need the Schwerkraftmaschine to work like an optical compressor, including the memory effect, but with attack and release still adjustable? Done.
Soft like a Vari-Mu? Exactly like a VCA? Also done.

And because that alone would leave the machine underchallenged, we created programs that have never existed in any compressor before, generating the control signal from complex rules.
We built and refined them in countless listening sessions. Pick the program that fits the song.

The side-chain filter

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

Prevent pumping with the low-cut filter.

Shift the focus towards the high or low frequencies with the tilt EQ.

The side-chain filter works in addition to the filters built into the compression modes.

The motor control

Every control is fitted with a servomotor which can move the pot into any position.
You can step in whenever you want: a slip clutch combined with the software always gives your hands the priority.

You do not need any of this modern network stuff? No problem at all.
The Schwerkraftmaschine can be operated entirely from the front panel, where it behaves like any other piece of hardware.

The network connection

Connect the Schwerkraftmaschine to your network. It fetches the settings it needs automatically via DHCP.
You could control the Schwerkraftmaschine from anywhere in the world: Sydney, L.A., or even Berlin.

The Plug-In

Load the plug-in into your favourite DAW and control the Schwerkraftmaschine from there. The motorized pots follow every movement.

Or grab the knobs on the device itself. Both stay in sync.

When you save your song, the settings of the Schwerkraftmaschine are saved with it. Open the session again next week, and every knob turns back to exactly where it was. A tube compressor with a fully analog signal path and total recall: that is the part analog hardware normally cannot do. What that means for a mastering chain that lives on revisions, and where the Schwerkraftmaschine sits behind the EQP-1: Analog Mastering Chain: What Goes Where and Why.
Schwerkraftmaschine Plug-in

Dual mono mode

The plug-in allows the Schwerkraftmaschine to be split into two separate mono channels.

Both channels then operate independently of each other, so two separate tracks can be processed individually.
All controls can be set separately for the left and the right channel.
The only things the channels share: they always use the same mode, and the Stereo Transformer mode is not useful in dual mono.

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

Since the physical front panel cannot be duplicated, this mode cannot be controlled on the device itself, but only via the plug-in.

Schwerkraftmaschine, VTC, or Creme?

Choose the Schwerkraftmaschine when one compressor character is not enough: it covers everything from gentle Vari-Mu to hard VCA behaviour, it can be remote controlled, and its VTC mode covers the sound of our Vari Tube Compressor. Choose the VTC when you want exactly that one soft, organic tube and transformer character and will never switch. Choose the Creme when you are after the pragmatic all-in-one solution with EQ and a more analytical compressor.

Network

Use our AI powered Setup Assistent: Setup Assistent

Switch the MODE knob to 12. This will display the status page of the Schwerkraftmaschine.

Also:
The plug-in will detect the Schwerkraftmaschine automatically if both are in the same network.

Use the plugins context menu to show the IP address of the Schwerkraftmaschine. You can also go directly to the Schwerkraftmaschine's website from the context menu.

The Schwerkraftmaschine gets its IP address from a local DHCP server in you network. You will find the DHCP server in your internet router or network server. Look for a list of taken IP addresses.

  • Check if you have the latest plug-in version installed.
  • Windows: Add a share for your DAW(s) to Windows Defender or other firewalls or antivirus programs: https://www.youtube.com/watch?v=IDewmCvFs2M.
  • If that doesn't help, email contact@tegeler.com with the following information:
    A detailed error description incl. OS version, DAW version, Plugin version, What exactly happens after you do what?
    Please send us screenshots of your network settings if applicable (see Quickstart Network Guide).

Option 1

Use a Wifi repeater with LAN connector.
It builds a bridge between the ethernet of the device and your Wifi network.

Option 2

Connect the device via network cable to your computer and enable internet sharing.

The device needs a DHCP server to get an IP address. Bridge the two network connections on your PC so the router's DHCP server can reach the device.



  1. Open Control Panel → Network and Internet → Network Connections
  2. Select both network interfaces (your router connection and the TAM device connection) by holding Ctrl and clicking both
  3. Right-click and select Bridge Connections

The device will now receive an IP address from your router and will be found by the plug-in automatically.


Set a static IP address on your PC's Ethernet interface manually.



  1. Open Control Panel → Network and Internet → Network Connections
  2. Open the Properties of the Ethernet interface connected to the device
  3. Select Internet Protocol Version 4 (TCP/IPv4) and click Properties
  4. Select Use the following IP address
  5. Enter IP address: 10.20.30.1, Subnet Mask: 255.255.255.0
  6. Click OK

Then open the plug-in and enter the IP address of your device manually:


  • 10.20.30.40 for the Schwerkraftmaschine
  • 10.20.30.41 for the Raumzeitmaschine
  • 10.20.30.44 for the Creme RC

Click OK. The plug-in will connect directly to the device.

Set a static IP address on your Mac's Ethernet interface manually.



  1. Go to System Settings → Network
  2. Select the Ethernet interface connected to the device
  3. Under Configure IPv4, select Manually
  4. Enter IP address: 10.20.30.1, Subnet Mask: 255.255.255.0

Then open the plug-in and enter the IP address of your device manually:


  • 10.20.30.40 for the Schwerkraftmaschine
  • 10.20.30.41 for the Raumzeitmaschine
  • 10.20.30.44 for the Creme RC

Click OK. The plug-in will connect directly to the device.


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.

At Share connection, select your internet connection (e.g. WLAN).
At With computer via: select the interface that is connected to the device.


Now the device will get an IP address and will be found by the plugin.
