When I try to setup each level for the speakers, I can't or I don't see Left Front and Right Front as an option. All I see is Center, Left Surround, Right Surround and Subwoofer. The only thing I am thinking about is maybe it's because for the Left Front and Right Front I am using the SPEAKER A connections which has the binding posts for the banana plugs. Would using SPEAKER B connections fix this problem? Shouldn't it be a non-issue with regards to using SPEAKER A or SPEAKER B connections? Anyone with XR50 encountered this problem? I just wanted to confirm before I try to remove the banana plugs and instead put flat pin connectors on my LF and RF speaker wires.
