Attack

The Gate attack control sets the speed at which the gate opens to allow signal to pass through it. This control is variable from 10 microseconds to 100 milliseconds. It is advisable to use slower Attack times when gating vocals or quieter instruments to avoid what is often described as gate ‘clicking’. This phenomena is not made by a mechanical device in the noise gate, but is rather, an audible manifestation of ‘no signal’to the presence of signal as the gate opens. The fastest setting is fully counter-clockwise (left) to the slowest setting all the way round to the right (clock-wise).
