Can a DAC do double duty?

Hi All,

I have Eversolo streamer going to DENAFRIPS Pontus via USB. Then XLR’s from Pontus to my processor. 
 

I have an older Pioneer Elite CD carousel which has coax. Can I go coax from CD player to Pontus, then Pontus to processor via RCA in’s on my processor?

Obviously I would be listening to either/or not at the same time. But is this doable? And if so does it do any harm to Pontus?

Thanks so much in advance!

Best Regards…
