INPUT / Gate
A Gate allows wanted signal through and attenuates unwanted signal. It has many
uses including removal of hum from an idle instrument or avoiding hearing the
snare drum through a tom microphone when only the snare is being played.
Attack – Adjust time it takes for the Gate to open once signal has reached
threshold.
Hold – Adjust time the Gate remains open after signal has dropped below
threshold.
Release – Adjust time it takes for the Gate to fully close once signal has fallen
under the threshold and hold time has expired.
Threshold – Adjust the level at which the Gate is triggered to open.
Depth – Adjust the amount the signal is reduced by when the gate is fully closed.
In/Out – Enable or disable the Gate.
