Hi I just purchased a polk surroundbar and a yamaha RX-V2600 receiver. I hooked up all the wires as instructed and I ran the optimizer YPAO to optimize the settings for the receiver. Everything came out ok EXCEPT it keeps on complaining about the polarity being wrong on the surround right channel. I double and triple checked the polarity on the back of the surroundbar and the receiver. It still gives me the same issue. I changed the wires and it still gives me the same crap. Do you guys think I have a defective surroundbar? Any other tips to try before I return the speaker to crutchfield? Thanks!
