Usage of S/PDIF and analog inputs of U24 XL at the same time

Our U24 XL features optical and coaxial S/PDIF digital inputs as well as analog inputs. We sometimes get asked if they can be used simultaneously and the answer is no: you can only use one stereo input at one time with 2 input channels for recording. This can be the optical S/PDIF input, the coaxial S/PDIF input or the analog line inputs. The selection is done via the control panel software of U24 XL.
