Details
Case 1: equal number of channelsIf both input buses contain an equal number of channels, the sample value of every channel at input S1 is multiplied to the value of the channel with the same number at input S2 and put to the same output channel.
Case 2: input with one channel
If one input bus contains one channel and the other input contains more than one channel, the sample value of the single channel input is multiplied to the value of every channel of the other input.
Case 3: unequal number of channels
If the two input buses contain an unequal number of channels, and neither has one channel, then the operator outputs no data and a warning is displayed below the symbol.
It is allowed to connect a signal that feeds back from the output to one of the inputs that originates from the output. It is however recommended to only feed back on the lower (S2) input.
It is not allowed to directly add signals from two different sources. You need to synchronize the signals first, using the Synchronizer ("Synchronizer").
The calculation is also performed on constant values (e.g. from a Constant ("K"); either if one of the inputs is a constant or both.
