toward the threshold level, the gain is reduced as determined by the knee control. The limiter knee is soft. The
ratio increases as the difference between the detector level and the threshold increases.
Limiter Knee Control
The “Knee” knob allows you to adjust shape of the limiter gain reduction. When the Knee control is set to 0,
the transfer function of the limiter is a classic “hard-knee” in which the compressor applies no gain reduction
when the detector is below the threshold, and the gain is reduced by the ratio when the detector level is at
the threshold.
