Hi all, I have a Toshiba 57HDX82 and just got my AV receiver (Onkyo TX-SR600). I will have a 5.1 speaker setup but was planning to use the TV speakers for the center audio channel until I can get a dedicated center speaker. The TV supports this function and on its back panel has a single RCA plug for center channel audio in. Problem is, my receiver doesn't have any type of RCA connector for center channel audio out, only speaker wire connection as far as I can see. There's got to be a way to send the signal; I'm just hoping someone knows of an adapter or can help me figure out how to rig it. The guy at Radio Shack came up with a solution that didn't work (connect the + and - speaker wires to 2 separate RCA male connector ends, then bring that into 1 connection with a Y-adapter). This made me a little bit nervous, and, um, it didn't work. (receiver made a popping sound and kindly shut itself off before I fried something). Any ideas would be appreciated.
