I have a Yamaha AW4416 with Digital in/outs on the rear panel. My owner's manual says the cable is a digital coax cable compatible with the IEC958 format. I went to radio shack and purchased a digital audio PCM RCA cable. Needless to say it didn't work. I don't know which cable to buy. What is a digital stereo cable? We're using it to run to an external Tascam CD burner w/ digital in's. Thanks for the help!!
