Hey peeps, I just bought a Toslink/fiber optic cable yesterday and thought I could hook it up from my Philips DVD player to the JVC mx-gt700 shelf system. However, after I tried, no sound was produced through the JVC speakers. I was wondering, do I need a receiver to use the toslink? Is there anyway I could make it work with just a dvd player and the shelf sound-system? Thanks in advance!
