Attack 0.20 to 5 Seconds
This adjusts how fast the AGC will increase gain.
Release 30.0 to 1 dB/Second
This adjusts how fast the AGC will reduce gain.
AGC Limiter Threshold -40 to +20dBu
The AGC is designed to add or remove gain slowly to maintain an average signal level.
Because of its slow nature a fast Limiter has been added to protect speakers from sudden tran-
sients. The Limiter threshold can be set from the top of the AGC Window up to +20dBu.
AGC Limiter Attack .01 to 200 m Sec
This is the speed at which the limiter starts to compress the signal once it has crossed the
threshold.
AGC Limiter Release 360 to 5 dB / Sec
Just like the release time on the compressor, the limiter's release time controls how fast the lim-
iter releases from gain reduction after the signal drops below the threshold.
Gate On/Off
Turns the Gate on and off.
Threshold -50 to 20 dBu
The threshold is the level at which the gate opens. Anything above the threshold passes, while
signal that is lower than the threshold is attenuated. Beware, setting the threshold to high can
cut off the tail end of signals as they fade out (the sustain of a guitar note, a held piano chord,
a reverb tail, etc.).
Ratio 1:1.0 to 1:15
