Compressor
Introduction
A Compressor is used to control the dynamic content of
a signal. It can be used both for levelling out the signal’s
dynamics (thereby letting your guitar sound stand out
clearer) and also for more radical, very recognizable
effects. The G-System provides three basic types of
compression. They assist you in finding the most
appropriate sound for your particular application.
Advanced Mode
This mode gives you access to all the common
compressor parameters. This means you have full
control over the compressor.
Sustaining Mode & Percussive Mode
In these modes, we offer fewer but very effective
“handles”. While the Sustaining Mode is used to achieve
rather extreme compression effects, the Percussive
Mode is more suitable for limiting purposes.
Illustration – Basic Compression
As this illustration shows, the output signal is attenuated
in accordance to the set ratio when the input signal
exceeds the Threshold point. The Attack parameter
specifies how fast the attenuation is achieved. Use the
Gain parameter to compensate the overall loss of level
that might result from compression.
Advanced Type
This type offers full control over all compression
parameters.
Threshold
Range: -40dB to 0dB
When the signal exceeds the set Threshold point, the
Compressor is activated. The signal’s level above this
Threshold point is processed according to the settings of
the Ratio, Attack and Release parameters (see below).
Ratio
Range: Off, 12:1 to Infinite:1
This parameter determines how hard the signal is
compressed. (see illustration above).
Example: With a Ratio setting of 2:1, an Input signal with
4dB above Threshold is reduced to only 2dB on the
Output. The Infinite setting gives you a Limiter function.
Attack
Range: 1ms to 140ms
The Attack time is the response time of the Compressor.
The shorter the Attack time, the sooner the Compressor
will reach the specified Ratio after the signal rises above
the Threshold point.
Release
Range: 50 to 2000ms
The Release time is the time it takes for the Compressor
to release the gain reduction of the signal after the Input
signal drops below the Threshold point again.
Gain
Range: -12 to +12dB
Use the Gain parameter to compensate for the level
changes caused by the applied compression.
Enable
Range: Off/On
The effect’s status. All settings are stored as part of the
preset even if this particular effect is disabled.
