Species the time from when the input level exceeds the threshold until the
compressor begins to operate. (msec)
REL Release Time
Species the time from when the input level falls below the threshold level
until the compressor stops operating. (msec)
THRES Threshold Species the signal level at which the compressor begins operating. (dB)
RATIO Ratio
Species the compression ratio at which the audio signal is to be
compressed.
GAIN Gain Adjusts the output level of the compressor. (dB)
Stereo Link
If this setting is on, the compressor settings of the adjacent channel will be
set so they’re identical to those of this channel.
