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.
NOVA System offers three types of compression.
Advanced for full access to all compression parameters
and sustaining
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.

Editing compressor parameters:
• Press COMP
• Change pages using encoder D
• Adjust parameters using encoders A-C
Advanced Type
This type offers full control over all compression
parameters.
Threshold
Range: -30 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.
Release
Range: 50 to 2000 ms
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.
