Yes, If you wish to connect the EXN100 to one single device, you can use any output, digital or analogue, that you wish.
If, however, you would like to connect the EXN100 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 if you wish to control the volume via the EXN100, you will need to enable Pre-Amp mode in the StreamMagic app. Volume control does not apply to the digital outputs.
