1) Depending on the settings of the controls gain and attenuation is possible. Value refers to the higher level on input or output.
2)
all Dynamics inactive
3) Conditional on physical principles, the setting of compressor and expander can affect the harmonic distortion performance. Data refers to inactive compressor and expander.
