Dynamics

A gate, or noise gate is an audio switch used to mute signals below a set 
threshold level. It can be used to suppress background noise and hiss from 
valve (tube) amps, effects pedals, and microphones.

Ducking is used to automatically reduce the levels of one signal when the 
level of a source signal exceeds a specified threshold. It is used for 
voice-over applications where, for example, level of background music is 
automatically reduced, allowing an announcer to be heard clearly.

sets the level at which the gate closes, cutting off the signal. 

Signals above the threshold level pass through unaffected. Signals at or 
below the threshold cause the gate to close.

For ducking, trigger signal levels at and above the threshold level activate 
ducking, and the signal level is reduced to a level set by the Range 
parameter.

The trigger signal is determined using the KEY IN parameter.

 controls the level to which the gate closes. It can be used to reduce 

the signal level rather than cut it completely. At a setting of –70 dB, the gate 
closes completely when the input signal falls below the threshold. At a 
setting of –30 dB, the gate only closes so far allowing an attenuated signal 
through. At a setting of 0 dB, the gate has no effect. When signals are gated 
abruptly, the sudden cut-off can sound odd.

For ducking, a setting of –70 dB causes the signal to be virtually cutoff. At a 
setting of –30 dB the signal is ducked by 30 dB. At a setting of 0 dB, the 
duck has no effect.

 determines how fast the gate opens when the signal exceeds the 

threshold level. Slow attack times can be used to remove the initial 
transient edge of percussive sounds. Too slow an attack time makes some 
signals sound backwards.
