The GSP-2101 Artist is equipped with DigiTech's Silencer™ technology. The Silencer™ Modules
offer seamless, professional-quality noise reduction that can be incorporated into your custom
Algorithms (the factory Algorithms are also equipped with the Silencer™ Noise Gate).
What is the Silencer™ technology? Well, Silencer™ Noise Gate and Noise Reduction Modules
shut down signals in the digital domain. This means that it can actually write digital zeros to the
Digital/Analog converters, ensuring the quietest noise reduction possible. The Noise Gate and Noise
Reduction modules are essentially the same module, except that the Noise Gate Modules are flexible
enough for use in any application. They include special controls that allow independent on-thresh-
old and off-threshold settings, while the Noise Reduction Modules have fewer Parameters, and are
easier to use. Noise Gates and Noise Reduction Modules can be found in the [MORE] library.
Silencer™ Noise Reduction
Silencer™ On / Off: Turns the Module on or off. When the Module is turned off, its
Parameters are not displayed but the signal continues to pass through the Module (i.e.
bypass). To see the Parameters, you must turn the Module on.
SNR Threshold : Sets the level at which the Silencer™ will disengage. Ranges from -3
dB to
SNR Release Time: Controls how fast the Silencer™ activates after the signal has fallen
below SNR THRESHOLD. Large numbers yield slow release times, while small numbers
give a fast release. Varies from 0 to 2000 milliseconds (2 seconds).
Silencer™ Noise Gates
Effect On / Off: Turns the Module on or off. When the Module is turned off, its
Parameters are not displayed but the signal continues to pass through the Module (i.e.
bypass). To see the Parameters, you must turn the Module on.
Threshold: Sets the level at which the gate will open. As THRESHOLD is modified, the
off-threshold (HYSTERESIS) setting maintains the same relative distance (in dB)
between them. This requires you to set only one Parameter to control both thresholds.
See HYSTERESIS. Ranges from -3 dB to -100 dB.
Hysteresis: Sets the distance (in dB) between the on-threshold and the off-threshold.
For example, if THRESHOLD is set at -40 dB and HYSTERESIS is set at 8 dB, the off-
threshold would be 8 dB below the setting of THRESHOLD, or -48 dB. Ranges from 0
to 12 dB.
Hold Time: Controls the amount of time the signal must remain below the off-threshold
before RELEASE TIME begins. This control should be set long enough to prevent false
triggering during long decay times. Ranges from 0 to 500 ms.
