I have a Pioneer CLD-D504 laserdisc player. It has a coax AC-3 output. I bought a gadget off Ebay that I thought would be able to convert the coax output to TOSLINK, so I can feed the output into an optical input on my processor (Emotiva UMC-200). The gadget doesn't seem to do anything, and I'm unable to determine if it really is faulty, or if there's something wrong with my setup. Has anybody tried this? Is there a particular demodulator/converter that works? I've been able to verify that my cables are good that the input on the processor is good.
