Hello Leo. Yes, this is possible (a corresponding adapter to a coaxial cable is supplied as an accessory). This MUST also work because the Ruark Audio R4 MKIII provides various operating modes (DAB, FM, CD, USB, Bluetooth, Front AUX, Rear AUX, Optical mode). - I have owned several units (for years) and am thrilled. Only the operation is not very user-friendly. Kind regards, Dänu
