| 1) |
Depending on the settings of the controls gain and attenuation is possible. Value refers to the higher level on input or output. |
| 2) |
- Compressor and Expander inactive
- (Ratio Controls at Position 1:1/Expander OFF)
|
| 3) |
Conditional on physical principles, the setting of compressor and expander can affect the harmonic distortion performance. Data refers to inactive compressor and expander. |
