Auto Fast

The  attack  parameter  is  a  crucial  factor  for  the  operation  of  a 
compressor. Choosing the right time setting is very important, 
but depending on the dynamic progress of the source material 

this is a difficult task – no matter if single tracks or complete mixes are 
processed.

If a very short attack time is chosen, the compressor is able to catch the 
short peaks, but on the other hand the sustaining signal will also be pro-
cessed, which might result in audible distortion. Longer settings reduce 
distortion significantly, but then the compressor is too slow for catching 
fast impulses.

This is where the Auto Fast function comes into play. If you set a longer 
attack and engage the Auto Fast mode, the attack time will be shortened 
automatically on fast and loud signal impulses. The compressor reduces 
the signal quickly and prevents it from slipping through.

Then the attack time directly and automatically returns to its original set-
ting. In Auto Fast mode the compressor can be very fast, but only when 
it is really needed.
