After the ungated signal is selected in the matrix, the decision of which ungated type of the signal is used is
made on the channels page on an input by input basis.
Ungated Version of Input Channel Processing Matrix Crosspoint
As described in Introducing the Polycom SoundStructure Product
signal processing paths that can be selected for each input. The different signal processing paths for the
four ungated signal types are summarized in the following table.

Non microphone channels
Most applications benefit from the Line Input ungated signal processing path for program audio and other
non-microphone audio that is not usually automixed.
