THRESHOLD
THRESHOLD (Soft Knee)
The second mode of operation, Hard Knee, is less straightforward to explain. Under
this condition, the Threshold control should be thought of as a compression gain control
instead of merely a traditional threshold control, as in the 1176-style compressors. In
this case, the effective threshold is predetermined, while the Threshold control acts as
an input gain stage. This results in the possibility of gain before compression in contrast
with Soft Knee operation, and allows for greater sonic flexibility over the resultant
dynamic range of the output. The Ratio control can be varied from very low values to
full limiting (infinity to one) in order to attain the most desirable result for any situation.

The final element in the control path of the Dynamics section is the Ratio control, which
has been covered in conjunction with the Threshold control previously in this discussion.
