Noise Gate

The noise gate allows an input signal to pass only when it exceeds a specified threshold level. Above the threshold level, the signal passes unprocessed. Below the threshold the signal is attenuated at the rate set by the ratio adjustment. The typical setting of the noise gate threshold is just above any noise level in the environment or source equipment. That allows signals that are above the noise to pass, and attenuates the noise when there is no signal, eliminating background noise.

Threshold — The input signal level below which attenuation (gating) begins (subject to attack time) and above which gating stops (subject to hold and release time).

The threshold level can be adjusted from -80.0 to 0.0 dB in 0.1 dB increments. Default is -65.0 dB.

Max Attenuation — The maximum attenuation of the signal when it drops below the threshold.

Maximum attenuation can be adjusted from

0.0to 80.0 dB in 0.1 dB increments. Default is 25.0 dB.

Ratio — The input signal level reduction when gating is engaged.

The ratio can be adjusted from 1.0 to 100.0 in 0.1 increments.

Default is 20.0:1.

Attack Time — Adjusts the time delay for gating to engage after the input signal level drops below the threshold level.

Attack time can be adjusted from 0.0 to

200.0ms in 0.1 ms increments. Default is 1.0 ms.

Hold Time — Adjusts how long gating continues once the input signal rises above the threshold. If the signal is still above the threshold when hold time ends, release time begins.

Hold time can be adjusted from 0.0 to 500.0 ms in 0.1 ms increments. Default is 300.0 ms.

Release Time — Adjusts the time it takes to return the signal to normal (unprocessed) levels once the signal has increased above the threshold level setting. Release time begins only after hold time is reached.

Release time can be adjusted from 10.0 to 1000.0 ms in 0.1 ms increments. Default is 1000.0 ms.
