Compressor module continued

Soft button

This activates the soft knee feature. A Knee control appears in

the controls section of the compressor. Increasing the Knee val-

ue causes the compressor to begin working slightly before the

threshold value and gradually adjusts the gain reduction ratio to

its set value slightly after the threshold value. This can be seen

as a curve around the knee point on the compressor graphic

display. This gradually increases the amount of compression as

the signal nears the threshold, and minimizes (softens) the audi-

bility of the compressor with program material that crosses the

threshold.

Knee slider

This control is visible only when the SOFT button is lit. It con-

trols how sharp the compressor responds near the threshold. It

ranges from 0.0 to 10.0 dB on either side of the threshold.

Limit button

Clicking this button causes the Ratio setting to jump up to its

maximum value. This essentially "Limits" the output signal to

never exceed a speciﬁ ed level. (Clicking it again will not turn it off, but moving the Ratio slider will.)

Note: The LIMIT button also lights if you move the Ratio slider to maximum.
