The CM series 70 volt amplifiers allow you to split the stereo inputs into separate input channels and then, using the matrix switching capabilities of these amplifiers, you can assign the individual inputs to any of the zone outputs.
To setup split inputs, open the settings menu by selecting the gear icon in the upper right corner of the web UI > open Input Sources > select the Split checkbox for the stereo inputs you want to split. You will now notice that the inputs are separated in both the settings menu and the input drop down menu for each zone.
After splitting inputs you can name each input in the Input Sources section of the setup menu. After renaming the input be sure to save changes by selecting the checkmark next to the name. Name changes will also appear in the Input drop down list for each zone.
