Looking to record music from digital recorder to iMac
Hi
Am looking to record music from a digital multi-track recorder to an iMac (likely onto audacity)... the iMac is "Core i5" 2.7 21.5-Inch (Late 2013). The only digital out on the recorder is a coaxial (S/PDIF RCA). The connections on the iMac are shown in pic.
Can either the thunderbolt or usb ports be assigned as audio inputs on the mac?
Can a coax to usb/thunderbolt cable be had?
Are cables such as these generally bidirectional?
Side note: I've been able to do just that on my older mac (iMac "Core 2 Duo" 3.06 21.5-Inch Aluminum (Late 2009)) because it featured an 'audio in/optical digital audio port).
New iMacs have nothing but usb-c connects... can these work as assigned digital audio in ports?
I hope my question is specific & to the point.
thx in advance
iMac 21.5″, macOS 10.15
