Limiter Mini is a device used to prevent signals from going over the threshold level. Commonly used in mastering as the final glue for a song and to increase the loudness.
Use to set the amount of audio signal volume sent into the threshold and limiting stage.
Set to determine where in the dynamic range limiting will be applied. Lower the threshold to apply more reduction of the dynamic range.
Release time controls for how long limiting is applied after a signal reaches the threshold. Another way to describe it is that it controls how fast the signal recovers after hitting the threshold.
The post gain knob scales the volume back up again after limiting has been applied.
