Gate Parameters
• GATE [OFF, ON]
This parameter turns the Gate module on and off.
• THRESHOLD [-70dB to 0dB]
Sets the level at which the gate will open. For example, if the THRESHOLD
parameter is set to -40 dB, any signal which exceeds -40 dB will open the gate. Any
signal lower than -40 dB will be attenuated by the amount determined by the RATIO
and MAX ATTEN settings.
The Gate Threshold Indicator (shown to the right) indicates when signal is below
threshold or above threshold. Set the THRESHOLD parameter so that the

system signal is present. Avoid setting the THRESHOLD too high as it can cause
signal tails and fade-outs to be abruptly cut off as the gate closes. Increasing the
HOLD and/or RELEASE parameters can also help reduce these artifacts.

(Gate Closed)

(Gate Open)
• RATIO [1:1 - 1:15]
Determines how much the signal will be attenuated once it drops below threshold. This control works opposite from
that of the compressor or limiter ratio control. If a RATIO of 1:4 is selected, a signal that is 1dB below threshold will be
reduced in gain so that it becomes 4dB below the threshold.
• MAX ATTEN [0dB – INF]
Sets the maximum amount of attenuation that will be applied by the gate. The range of this control is variable between
0 dB - Infinity. 0 dB attenuation means that even though the gate is “closed” there is no gain reduction. Infinity (INF)
applies an infinite amount of gain reduction, resulting in no output when the gate is closed.
• ATTACK [100µs - 200ms]
Sets the speed at which the gate opens once threshold has been exceeded. It is typical for very fast attack times to be
used to catch the fronts of transient signals.
• HOLD [0s - 500ms]
Sets the amount of time the gate is held open after the signal falls below threshold.
• RELEASE [360dB/s - 5dB/s]
Sets the rate at which the gate “closes” or attenuates the signal once the end of the HOLD time is reached.
