A single RCA audio cable, like this…
…plugged from the coaxial output port of the Demodulator to the coaxial input port of your receiver/amplifier will work just as good.This setup got me through before I upgraded to HDMI ports.
Edit:
If you are connecting to an audio card of your computer, you’ll need an RCA Male to 3.5mm Male Cable, like this…
Thanks! Got it. I’m planning to connect the demodulator to the S/PDIF port on my MOTU ultralite audio interface. Its worked fine so far connected directly from my laserdisc player, but I haven’t been able to test the digital coax output yet for lack of cabling.
