My son has an iMac in his room connected to his Panasonic receiver via a long (12Ft) mini-toslink cable I found for a reasonable price at monoprice. Take a look at product ID 1558 for an example
iMac Combo Headphone/Optical Out Port Cable
I just picked up a used Apple G5 iMac (2005 model) that has a combination analog/optical digital audio output port. The output on the iMac is a mini plug. I want to use it to digitally connect to a Panasonic receiver and I can use either an optical Toslink and S/DIF RCAs input. I can't find a cable that does what I want. Anybody know how to connect this setup?
