DSP ELEMENTS ACS COMPRESSOR
GAIN
Adjust the ma e-up gain of the Compressor
Gain applied after the compressor to account for level lost in compression.
THRESHOLD
Adjust the Threshold level of the compressor
When the signal exceeds the threshold, it will be attenuated according to the ratio setting.
RATIO
Adjust the Ratio value for the Compressor
The ratio between the amount that the normal signal level has exceeded the threshold and the level above
threshold it will be attenuated to. For example, if the threshold is set at -10dB and the ratio is set to 2:1, when a
signal level of 0dB (10dB above threshold) comes in, it will be attenuated to -5dB (5dB above threshold, which is
10dB divided by 2). In the same instance, if the ratio was 5:1 then the signal would be attenuated to -8dB, which is
2dB above threshold (10dB divided by 5). Essentially, the higher the ratio, the more the signal is 'squashed'..
G in Re ti n Mete
Indicates amount of gain reduction currently being applied by the compression process.
COMP On O
Switch the compression process on or off.
Pressing and holding the key will activate Interrogate mode for this function (see the Mix Features 8.3).
