4.1 Compressor Threshold Control
The threshold control sets the level (referred to dB FS) at which compression and gain
reduction will begin. The control has a linear decibel law over the range. The following
graph illustrates the threshold control operated in 5 dB increments with the ratio at max
(1000:1) to –20 dBr.
4.2 Compressor Ratio Control
The ratio control sets the rate at which gain reduction will occur when the input level goes
beyond the set threshold level. The control has a 1/Ratio law so that gentle compression
can be achieved despite the wide range of the control. So, from 1:1 to 2:1 ratio occurs
over the first 50% of the control range and 4:1 ratio occurs at 75% control rotation etc.
Full limiting is achieved with the control at 100%.
