This tab is only available to you if the selected device software is version 2.0 (firmware, see status line) or higher (menu Controller). The settings in this tab allow you either to amplify the input signals of the individual knocking sensors or to attenuate them (values <100) in order to suppress signals similar to knocking signals. Values between 0 and 300 can be specified. The default setting is 100. This value can be restored via the button Default .
