REFERENCE - Attack & Auto Fast Attack
Attack
Here a Burst signal (a sine tone that is boosted by 12 dB for a period of 100ms) is used to demon-
strate the eectiveness of the Attack controller. The dierent curves show how fast this level jump
is reduced by 4dB. On fast settings the reduction takes only a few milliseconds, on longer settings
the reduction does not only take longer but it is also smaller. Therefore on fast Attack settings the
Gain reduction is always higher than on longer settings.
Auto Fast Attack
Utilizing a Burst signal again, this diagram shows a comparison between a normal Attack time of
50ms (blue curve) and the later added Auto Fast function (green curve). This reveals how fast this
circuit reacts: Even the rst waves of the Burst are already reduced by 2,3dB. Also the Gain reduc-
tion as a whole now happens much faster. Note: This function starts working at -3dB; on lower Gain
reductions the changes in dynamics are too small.
