3.2 Compressor Section 5. Threshold Control This control adjusts the threshold level for the Compressor section in the range of -40dBu to +20dBu. The SKC(Smart Knee Control) is applied to the audio signal, which is a maximum of 10dB above the set threshold.Above such level (10dB) a hard knee compres...

13. SC Monitor Switch You can connect the sidechain control signal to the audio output by mean of this switch and at the same timeyou will also mute the audio input. In this way you can also monitor the sidechain signal being returned viaexternal signal processors. 14. Sidechain Filter Switch A low-...

4.3 Peak Limiter Section How fast is the compressor to react to a signal which is above the threshold point? This is determined by theattack time. A longer attack time is advisable to process low frequencies while shorter attack time is preferablefor high frequencies. IN this way you will avoid unde...
