If you wish to connect the CXN100 to one single device, you can use any output, digital or analogue, that you wish.
If, however, you would like to connect the CXN100 to more than one device at a time, you can connect up to four devices and play simultaneously, as all outputs remain active at all times.
Please note that you will need to enable Pre-Amp mode in the app, if you wish to control the volume via the CXN100. This will only control the volume of the analogue outputs.
