Gate On/Off
Turns the Gate on and off.
Threshold -50 to 20 dBu
The threshold is the volume 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
This is where you decide how much downward expansion you want. This ratio works opposite from that
of the compressor or limiter. If a ratio of 1:4 is selected, a signal that is 1dB below the threshold will be
reduced in gain so that it becomes 4dB below the threshold.
Attack 0.1 to 200 m Sec
As the signal reaches the threshold area, the Attack control sets the speed at which the gate opens. Use
very fast attack times to catch the fronts of transient signals.
Hold 0 to 500 m Sec
The Hold control sets the amount of time the gate is held open after the signal passes below the
threshold point.
Release 360 to 5 dB
Release sets the speed at which the gate “closes” or attenuates when the end of the Hold time is reached.
Max ATT 0 to Inf. dB
This sets the maximum amount of attenuation for the gate.
3.9 - Notch Filters
The notch filter is the perfect tool for dropping out undesirable frequencies that may appear in the input
signal.
Notch On/Off
Turns the notch filters on and off.
Frequency (1 to 6) 20 to 20K
Selects the desired notch filter frequency of the selected notch filter.
