NOISE GATE
The noise gate works by cutting any sound below your set threshold level, an exam-
ple would be the removal of hiss from high compressor settings. Like the compres-
sor, this effect is not instantaneous and the duration needed to ramp up or ramp
down is set using the attack and release controls. The
ATTACK
is the time needed to
restore the signal once the level is above the threshold:
RELEASE
is the time required
for the removal of a a sound below the threshold.
The LCD displays the voices assigned to the gate (lead, harmony, none or both) and
the softknob controls.
THRESHOLD
(-70dB - 0dB): controls the level below which all sounds are removed.
ATTACK
(1ms - 40ms): sets how long it takes for the sound to fall silent.
RELEASE
(10ms - 3000ms): sets how long it takes for the sound to reappear.
