Compressor
Introduction
A compressor is used to control the dynamic content of a
signal. It can be used both for leveling out the signal’s
dynamics (thereby letting your guitar sound stand out
clearer) and also for more radical, very recognizable
effects.
G-Natural offers two types of compression. “Stomp”, that
offers only a few but effective handles similar to the ones
found on stomp-box pedals, and “Studio” which with its
extra parameters allows for greater control of the
behavior of the compression.
Illustration – Basic Compression
As this illustration shows, the output signal is attenuated
relative to the set ratio when the input signal exceeds the
threshold point. The attack parameter specifies how fast
the attenuation is achieved. The Level parameter allows
you to manually compensate for the perceived level
difference resulting from compression.
G-Natural compressors
G-Natural has separate compressors for the
Instrument Inputs and the Mic/Pre input.
Editing compressor parameters:
•
Press and hold COMP to select between “Instrument”
compression and “Mic/Line” compression. The
different compression modes are indicated by “M” for
Microphone/Line or “I” for instrument in the right side
of the display.
•
Press COMP once or more to select either Studio or
Stomp type
•
Adjust parameters using encoders A-D
Studio Type
This type offers full control over all compression
parameters.
Threshold
Range: -40 dB to 0 dB
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, 1.12:1 to Infinite:1
This parameter determines how hard the signal is
compressed.
Example: With a Ratio setting of 2:1, an input signal with
4 dB above threshold is reduced to only 2 dB on the
output. The “infinite” setting gives you a limiter function.
Attack
Range: 0.3 ms to 140 ms
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.
