56 PLM Series Operation Manual rev 1.1.39. Front Panel InterfaceGroup sum displaysSome of the PLM’s parameters display two values instead of one. The parameters concerned are:Module > Gain▸Module > Delay▸Module > Limiters > MaxRMS Level▸Module > Limiters > MaxPeak Level▸For each of these parameters, the primary value, which is adjusted by the rotary control, is shown above theGroup Sum value, which is displayed in brackets.The Group Sum parameter value will initially be the same as the primary value. However, as Lake ProcessingModules may belong to Groups (possibly spanning mutilple Frames), and these parameters may be adjustedin the Lake Controller software for the whole Group, it is useful for the effect of this additional Groupadjustment to be taken into account. The Group Sum parameter value is effectively the sum of the individualModule value plus any gain, delay, etc. that has been applied to the whole Group.Menu structureFrom the top page of the menu system, the following seven submenus are available:Module▸Input configuration▸Attenuation▸Frame▸Frame Preset▸Load Monitoring features▸Dante▸9.13.2 Module submenuThis submenu is selected by pressing soft button 2, named Module from the menu top page.MenuGainDelayPolarityMuteLimitersAmp GainModuleFigure 9.13.2: Module menu viewThe options available are as follows:9.13.2.1 GainThis option is selected by pressing soft button 2 (Gain) from Menu è Module.
