Recently I tried to stream a radio station through my computer and input into my receiver (Denon AVR 3802). I used an adapter to go from my speaker terminal on my computer to 12 gauge speaker wire. The length is approximately 60 to 75 ft long. I couldn't get any sound out of my receiver. Then I hooked up my computer to my receiver with a small/cheap left/right audio cable that is approximately 4 ft long. Now, I can get sound out of my receiver, but it is very poor sound (I tried a music CD and get the same results). Now I have two problems: 1) My computer needs to be in a different room (i.e. 60 to 75 ft away) and 2) I have poor sound when it does work. I assume that there is too much signal degredation in the 12 gauge, 75 ft speaker wire. Do I need an amplifier? Any help would be appreciated. Thanks.
