With the compressor, the level is automatically adjusted
to the optimum setting according to the threshold
(Thres) and ratio (Ratio) settings. In addition, since
lengthening the attack (Attack) setting may result in
distortion, a buffer (margin) of -6 dB is provided. Adjust
the following parameter levels as needed.
