The relationship between the input signal and the output signal above a threshold value. This value defines the slope of the output signal above the threshold.
A ratio of 2:1 indicates that for every 2 dB the input signal is above the threshold, only 1 dB will be observed in the output signal. At a ratio of 10:1 and higher, limiting occurs.
Default value: 1.5
Range: 1 to 50
