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
This is where you decide how much downward expansion you want. This ratio works oppo-
site 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 Attenuation 0 to Inf. dB
This sets the maximum amount of attenuation for the gate.
The ZonePro™ offers a de-Esser module. This De-esser effect is ideal for removing unwanted
vocal sibilance. These parameters are user adjustable on all programs and are as follows:
