EFFECTS - NOISE GATE & BOOST
Noise Gate
A Noise Gate is generally used to attenuate the signal when no signal is present and thus attenuate the hiss, hum and other noise you might have on your system. Of course a Noise Gate is not the solution to any noise problem. You should try to avoid the noise in the first place. Problems with noise can be introduced by a number of different things. In a guitar signal chain the typical problems are; poor cables, poorly shielded pickups, power supplies placed close to signal cables and other pedals.
There will, however, always be a certain amount of noise in any setup. The Noise Gate can help you attenuate the noise when you are not playing. Be careful when setting Threshold and Release parameters. A too high Threshold setting will result in e.g. not “opening” the Gate. A too slow Release time will result in cutting your attack.
As the microphone and guitar signals are of quite different nature,
The Noise Gate parameters are placed in the EQ block after the EQ parameters.
•Press and hold the EQ button to select between instrument and Mic/Line inputs.
•Be sure that “Gate” is set to “on”

Mode
Range. Hard or Soft
General overall mode that determines how fast the Noise Gate should attenuate/dampen the signal when below Threshold.
Threshold Range: -60dB to 0dB
The threshold point determines at what point the Noise Gate should start attenuating the signal.
To set this parameter; set the Damp parameter to e.g. 50 dB. Then start turning up the Threshold value from
Damp
Range: 0 dB to 90 dB
This parameter determines how hard the signal should be attenuated when below the set Threshold. You could argue that a max dampening would be appropriate always, but you would also like to have a smooth transition between the “gated/attenuated” stage and the “open” stage. The more dBs that must be released the more obvious the Noise Gate might seam.
Release
Range: 0 dB/sec to 200 dB/sec
The Release parameter determines how fast the signal is released when the Input signal rises above the Threshold point. As a rule of thumb this setting should be set fairly high.
Boost
Press BOOST to enter the boost menu.
The boost level can be set for each preset within the range of the Max Boost parameter. The Max Boost level is set in the levels menu.
