|
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. |
