To demo this plug-in, you can simply download it from the product page and run it up in your host - the software will guide you through the rest of the process.

  1. Download and install the plug-in.
  2. Open your DAW/host.
  3. Insert the plug-in to commence activation (sometimes this will happen when the plug-in is scanned on startup, depending on your DAW/host).
  4. When you see 'Activation is required', click 'Try'.
  5. Log into your iLok account and click 'Next'.
  6. Select a location to activate the license to, and click 'Next'.


Installation and Download

We recommend using the SSL Download Manager application to to easily manage all SSL plug-in installations all from one place, on both macOS and Windows. In addition to easily installing, uninstalling or reinstalling individual or every SSL plug-in at the click of a button, the SSL Download Manager also provides you with detailed release notes and lets you know when updates are available.

You can also download offline installers for a plug-in from here.

All SSL plug-ins are supplied in VST, VST3, AU (macOS only) and AAX (Pro Tools) formats.

The installers provided (macOS Intel .dmg and Windows .exe) copy the plug-in binaries to the common VST, VST3, AU and AAX directories. After this, the host DAW should recognise the plug-in automatically in most cases. Simply run the installer and you should be good to go. You can find more information about how to authorise your plug-ins below.



Visit iLok, Licensing and Activation for guidance in activating your SSL plug-in.



The input/output area of the plug-in allows access to gain controls, MIX, and displays the current gain reduction on a VU meter.


Input and Output Meters

The meters either side of the plug-in indicate the instantaneous input/output levels to/from the plug-in.


Applies a gain to the input signal.


Applies a gain to the output signal.


Automatically applies a makeup gain in addition to the OUTPUT GAIN, to compensate for the input gain.


Sets the blend between the processed signal and unprocessed signal.

VU Meter

Displays the instantaneous gain reduction applied to the signal, in dB.



The center section of the plug-in lets you define the response of the compressor.



Use this to dial in a vintage-style harmonic drive. The LEDs around the control indicates the amount of total harmonic distortion introduced.


Sets the ratio of the compressor. Each ratio provides a unique compression curve and characteristic, including threshold offset.

When in BLITZ! mode,

See below for more information.


Adds an addition modulation to the initial attack of the compressor.

See below for more information.


Sets the attack of the compressor envelope.


Sets the release of the compressor envelope.


Overrides the ratio and drops into "all-buttons-in" BLITZ! mode for brick-wall limiting.



Each ratio provides a unique compression curve and characteristic, including different threshold offset and attack and release responses.

When combined with different attack and release settings, you can emulate the different responses of a wide range of classic hardware compressors of different types e.g. opto, tube, VCA, FET.

1:1 drive only and no compression, for warming the signal add character
1.5/2/3:1 transparent and gentle compression with a wider "parabolic" knee and very gentle curves level your signal during tracking
4/6/8:1 easy slope after a narrower knee, and recommended starting points for most signals great for vocals, bass and acoustic instruments
10/20:1 these special "opto" modes can be used to closely emulate the nonlinearities of gain structures from vintage opto-VCA tube compressors and classic leveling amplifiers drums
BLITZ! brick-wall limiting smash room mics

Some useful starting points for different types are provided as presets, accessible via the Preset Manager interface.



As you dial in this parameter, the shape of the initial attack will automatically slow down on more transient signals. This emulates an effect often present in older analogue compressors when processing heavily.

When used subtly, it introduces an overshoot to particularly percussive inputs. When used to the extreme, this will give the impression of a longer attack time.


Detection Sidechain

The Detection Sidechain controls allow you to apply filtering and EQ to the sidechained signal. This allows you to control which frequencies the compressor is most sensitive to, or which frequencies it ignores.



Removes low-frequency components from the sidechain signal, below the frequency specified.

Use the the highpass control to protect the compressor from low frequency, which can be especially useful to prevent kick drums and other low frequency instruments from causing pumping and modulation in the compressor response.


Sets the center frequency of a bell filter applied to the sidechain.


Sets the Q factor of the sidechain bell filter.


Sets the gain applied to the frequencies specified by the sidechain frequency and Q parameters.


Auditions the effect of the filters on the input signal. Note that this is not technically the sidechain signal, since the sidechain contains the compressed output, not the input. 



All of our plug-ins ship with carefully designed presets to aid your workflow.

Factory presets are included in the plug-in installation, installed in the following locations:

macOS: /Library/Application Support/Solid State Logic/PlugIns/Presets/[Plug-in Name]

Windows: C:\ProgramData\Solid State Logic\PlugIns\Presets\[Plug-in Name]


Switching between presets can be achieved by clicking the left/right arrows in the preset management section of the plug-in GUI, and by clicking on the preset name which will open the preset management display.

The Preset Management menu reflects the folder structure of the preset folder.

Revert Changes and Delete

  • Revert Changes discards any changes to the current preset.
  • Delete removes the current preset from the filesystem. Factory and Producer presets cannot be deleted from the plug-in GUI, although they can be manually deleted using the filesystem (Windows Explorer or Finder).

A/B and Copy

  • A/B allows you to toggle quickly between two presets. This is useful for comparing between two parameter settings.
  • COPY X TO Y is used to copy presets between A/B.




SSL plug-ins come with a built-in UNDO/REDO stack, in case your DAW doesn't handle this.

  • UNDO undoes the current action in the history stack.
  • REDO re-does the next action in the history stack.


HQ mode


Click the HQ button to drop the plug-in into High Quality mode. This introduces intelligent oversampling (introducing the minimum amount of oversampling required).
