Attack
Here we see how a burst signal (a sine wave which is boosted by 20 dB for a period of 400 ms in this
case) is used to demonstrate the effectiveness of the attack controller. The different curves show
how fast the jump in level is reduced by 10 dB. When fast settings are applied, the reduction only
needs a few milliseconds. Longer settings, on the other hand, do not only need a longer period of
time, but also produce a smaller overall amount of decrease in level. Therefore fast attacks always
produce higher amounts of gain reduction than longer ones.

Auto Fast
Based on using a burst signal again, this diagram shows the comparison between a normal at-
tack time of 200 ms (darker curve) and the attack characteristic with activated Auto Fast function
(lighter curve). You can easily see how fast the circuit reacts, as even the first waves of the burst are
already reduced by 3 dB. On top, the overall amount of gain reduction happens much faster then.
Note: This function starts working at about -3 dB, because lesser amounts of gain reduction do not
include sufficient changes in dynamics.
