When the signal exceeds the threshold, it will be attenuated according to the ratio setting.RATIOAdjust the Ratio value for the CompressorThe 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’..Gain Reduction MeterIndicates amount of gain reduction currently being applied by the compression process.COMP On/OffSwitch the compression process on or off.Pressing and holding the key will activate Interrogate mode for this function (see the Mix Features 8.3).7.2.3: DSP ELEMENTS > ACS > COMPRESSOR
