The interface of FabFilter Pro-C 2 is designed to be easy to use while providing all necessary
information and controls. It consists of the following elements:
The animated level display shows you the incoming and processed audio signals together with the
gain reduction. It helps you detemine the correct compressor settings. You can hide the level
display with the Display button. This will also hide the knee display and change the vertical
level meters to horizontal ones, making Pro-C 2 look and feel more like a traditional
compressor. See Displays and metering.
The Knee display visualizes the input/output transform of the detection circuit, including the
effect of the Threshold, Ratio, Knee and Range parameters. It conveniently uses the same scale
as the level display underneath. Use the Knee button to show or hide the knee display. See
Displays and metering.
Dynamics and time controls
Floating at the heart of the interface, there's a panel with the main compressor controls.
Threshold, Ratio, Knee and Range control the triggering and how much compression is applied.
The Attack, Release, Lookahead and Hold affect the smoothing and curves of the gain reduction.
See Dynamics controls and Time
At the right-hand side of the interface, the input-, gain reduction- and output level meters
and their read-outs provide an immediate overview of the current levels. The input and output
level meters show both peak and loudness levels. The loudness level complies with the
Momentary mode of the EBU R128 / ITU-R 1770 standards. See Displays and metering.
MIDI Learn lets you easily associate any MIDI controller with any plug-in parameter. See
The Oversampling setting sets the amount of internal oversampling, which reduces possible
aliasing for fast/aggressive dynamics processing, at the cost of additional CPU usage. See
Input and output options
At the right of the bottom bar, you can bypass the entire plug-in and adjust the initial input
and final output levels. See Input and output options.
Resize and Full Screen mode
The Resize button at the far right of the bottom bar selects between various interface sizes.
In addition, click the Full Screen button at the right top corner of the interface to let Pro-C
2 fill the entire screen. See Full Screen mode and
Presets, undo, A/B, help
With the preset buttons, you can easily browse through the factory presets or save your own
settings so you can re-use them in other songs. The Undo, Redo, A/B and Copy buttons at the top
of the plug-in interface enable you to undo your changes and switch between different states of
the plug-in. Finally, the Help menu provides access to help and version information. See
