5 Controlling StudioLive RM-series Mixers with the CS18AI
5.3 Processing Signals with the Fat Channel
Compressor
The Compressor meter in the Selected Channel area displays the amount
of gain reduction currently being applied by the compressor.
Compressor On button toggles the compressor on and off for
the selected channel or output bus. The button will illuminate
to indicate that the compressor has been enabled.
Compressor Threshold sets the compressor threshold for the selected
channel or output bus. When the signal's amplitude (level) exceeds
the threshold setting, the compressor engages. Turning the knob
counterclockwise lowers the threshold so that compression begins at
a lower amplitude. The threshold can be set from -56 to 0 dB.
Ratio sets the compression ratio (or slope) for the selected channel or output
bus. The ratio sets the compression slope, which is a function of the output
level versus the input level. For example, if you have the ratio set to 2:1, any
signal levels above the threshold setting will be compressed at a ratio of
2:1. This means that for every 2 dB of level increase above the threshold, the
compressor's output will only increase 1 dB. The ratio can be set from 1:1 to 14:1.
