The available range is from -20 dBu to +12 dBu; • Attack determines how fast limiting will engage when the signal exceeds the limiter Threshold. The available values is from 1 to 6; • Recovery (Release) is the time it takes for the compressor to stop processing after the signal drops below the Threshold value.
