Operation

This module is for noise cancellation when there is no signal.

The input signal is output as-is, but whenever theinput signal level drops below a certain value for a specific time the gate closes and output is muted.

1.Bypass

Effector function enable/disable. Selecting bypass causes the input signal to be output as-is.

2.Threshold

Noise gate operation threshold level. Output is muted when the input signal is at or below the level specified here.

3.ReleaseTime the noise gate is closed when muting is performed.

Operation

This effector lowers the volume when the input signal is at or above a specified level. This function can be employed to achieve either of the two objectives described below.

Compressor

Volume is raised when the input signal is small and lowered when the input signal is large. This suppresses wide variations in volume levels, which makes it possible to sustain decay type instrument tones longer.

Limiter

Since the operation start level is set comparatively higher than that of the compressor, when the input signal as at or below a certain level, it is output as-is. When the input signal is at or above a certain level, the input the output amplification factor is reduced, which suppresses the output signal peak.

1.Bypass

Effector function enable/disable. Selecting bypass causes the input signal to be output as-is.

2.Attack

Level of attack for the signal rise. Theoretically,it controls the time it takes from the point the input signal rises to a preset level until the compressor/limiter effect is applied. A late attack keeps the signal attack part from being compressed, which makes it possible to maintain the attack only.

3.Release

Time from the point when the input signal drops below the threshold level until the compres- sor/limiter function stops
