Compressor module continued
Attack slider
This control determines how fast the compressor re-
acts once the threshold has been exceeded. It ranges
from 0.25 ms to 250 ms. For a softer attack, move the
slider more to the right.
Release slider
This determines how fast the compressor turns off
once the signal falls below the threshold. It ranges
from 0.25 ms to 2.5 sec.
Threshold slider
This sets the level at which the compressor begins to
act on the incoming signal. It ranges from –60 dB to
0 dB.
Ratio slider
This determines the change in output level as a func-
tion of the change in input level, once the threshold
has been exceeded. It ranges from 1.0:1 to 20.0:1.
When this slider is set to 20:1, the LIMIT button automatically lights. It will go out if you reduce the
Ratio.
Gain slider
Use this to compensate for the loss of gain caused by the action of the compressor. It ranges from
0.0 dB to 24.0 dB.
