AUNE X1s question

I am after a DAC which includes analogue in and Digital coax out, something like the AUNE X1s.

I will be using it to feed multiple sources to a miniDSP OpenDRC-DA8 which has the volume control built in.

The question I have regarding the AUNE X1s is does it convert the analogue in into digital that can be fed out the coax digital out, ie an Analogue to Digital Converter? None of the online reviews I can find covers this.

If not, does anyone know of a product that does? (at reasonable cost).

Thanks in advance
Mark
