REFERENCE – Attack & Auto Fast Attack

Attack

Here a burst signal (a sine tone that is boosted by 12 dB for a period of 100 ms) 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 4 dB. 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 the amount of gain reduc-

tion is always higher on fast attack settings than on longer settings.

Auto Fast Attack

Utilizing a burst signal again, this diagram shows a comparison between a normal attack time of

50 ms (dark curve) and the later added Auto Fast function (light curve). This reveals how fast this

circuit reacts: Even the rst waves of the burst are already reduced by 2.3 dB. The whole gain re-

duction now happens much faster, too. Note: This function starts working at -3 dB; on lower gain

reduction values the changes in dynamics are too small to trigger it accurately.
