Gate/Expander module continued
Attack slider
This adjusts how fast the gate opens once the
threshold has been exceeded. It ranges from
0.25 ms to 2.5 sec.
Release slider
This determines how fast the gate closes once the
signal falls below the threshold. It ranges from
0.25 ms to 2.5 sec. The release time follows the
hold time.
Hold slider
This determines how long the gate remains open
after the input signal has fallen below, and remains
below, the threshold. It ranges from 0.0 ms to 10.0
sec. The release time is in addition to the hold time.
Threshold slider
The threshold is the level at which the gate acts on
the incoming signal. The slider lets you adjust the
threshold anywhere from –60.0 dB to 0.0 dB.
Range slider
This determines the amount of gain reduction applied to the signal once the signal level drops below
the threshold. It ranges from 0.0 dB to 100 dB. (This slider is not visible when EXPAND is on.)
