Navigating the 'Compressor Pro'

'Compressor pro'
Whilst you could be forgiven for feeling perhaps a little overwhelmed at the in-depth front panel of the Compressor Pro. You'll be glad to hear that the controls and layout of the Compressor Pro are actually hugely intuitive and everything's laid out where you'd expect it to be. Take a closer look with us down below!


ThresholdThis is probably the most important control on the Comp Pro. It is adjusted to determine when the compressor is working or when sound is being passed through unaffected.


Ratio“the Compression Knob”, Ratio is the amount of compression you set the Comp Pro for. You can set it from No Compression (1:1) when all of the way off or CCW.


AttackAttack Times between 0.15ms and 150ms. Controls the time it takes for the Comp Pro to start compressing.


ReleaseRelease Times between 0.1s to 3s. Controls the time before the Comp Pro releases or stops compression .


GainThis is the output level of the compressor. It does not affect the compression controls like THRESHOLD, RATIO, ATTACK or RELEASE.


AutoOFF/ON – Set to ON in most cases for automatic setting of Attack and Release Times. This will sound natural and work in a very large number of cases.Hard Knee/Soft Knee.


KneeHard Knee Compression follows a hard fast rule: If THRESHOLD is met, then Compress at this RATIO. Soft Knee is Komfort Kompression.
