Reduces the level of signals that fall below a threshold level.
Features an exponential attack and reverse exponential release, which helps to preserve the natural decay of the instrument or signal source, rather than imposing a synthetic envelope upon it.
Show Side chain: A side chain input can be made available so that an equalizer for example can be introduced to make compression frequency conscious. Any side chain processing would normally derive its signal from the same source that is fed to the audio input of the compressor.
Stereo: Makes the Compressor stereo. Note: Controls will stay the same, adjusting both sides equally.
Threshold control: Adjusts the level threshold below which gain reduction will take place. Above this threshold, no gain reduction will take place.
Range control: Adjusts how 'deeply' the gate will reduce the signal level of below-threshold signals.
Attack control: Adjusts the time it takes for the gate to recover after the signal level goes above threshold.
Hold control: Extends the 'gate-open' phase to prevent 'chatter'.
Release control: Adjusts the time it takes for the gate to respond to signal levels which fall below the threshold.
Bypass button: Removes the gate from the signal path.
Manual Open button: Tests the attack/hold/release settings without having to manipulate the signal level.
Below Threshold meter: Displays the input signal level relative to the current threshold setting.
Note that it is normal for this meter to show erratic readings when the threshold is set to very low values.
Open indicator: Shows when the gate is not reducing the signal level.
! The gate can cause distortion at low frequencies when the Release control is set to low values. Unless you particularly need the gate to attenuate very quickly when the signal falls below threshold, set the Release control to a reasonably high value.
