COMPrime reduces the dynamic range i.e. the difference between quiet and strong sounds. Quiet sounds are amplified by the makeup level, while the louder ones are first affected by a gain reduction.

Adjustable compression parameters:

Attack time: the time needed to attain full gain reduction
Release time: the time to recover from a gain reduction phase
Threshold: minimum level of input signal needed to activate gain reduction
Ratio: ratio of input level further threshold that is sent to the output
Knee: compression curve can be chosen between soft knee or medium (harder) knee
COMPrime has a hot tube in it's core. It gives you the famous analog non-linearity that creates a warm and rich sound.
Setting a long attack on any compressor causes an overshoot. This has an interesting percussive effect but can cause overloads. COMPrime uses a special attack processing to reduce early overshoot peak while keeping most of its body for transient amplification.

COMPrime recovers faster from short transients than from long gain reduction phases. This reduces pumping effect on fast changing signals and avoids bass distortion on slower changes with longer release.

Bass distortion reduction
COMPrime recovers slower from low frequency transients to reduce bass distortion.
