thanks gonk! now I have a tough one for ya....

after connecting the Denon 2900 using RCA, we are only getting sound out of; are you ready for this one?? Sound is only coming out of front right speaker and left surround speaker....nothing from left front, center, sub, or right surround...

all RCA connections appear to be connected correctly.....operative word being "appear." ha

I am sure this is a very elementary question / problem for you.......so where did we go wrong in this hook up??
