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 compression will be applied.
3. Ratio Control
This control determines the expansion ratio when the signal drops below the threshold level. The expansion ratio can
be set from 1:1.2 to 1:8 (Low ratio level for Expander application or 1:8 for Gate application).
4. Threshold LED
The "+" Led lights up when an audio signal is below the set threshold. The "-" Led lights up in presence of an
expansion
