You need to set your unit to "stereo". That's the maximum you can get without matrixing/decoding/equalizing or whatever you call it.

Your unit appears to be capable of handling inputs of only two analog channels. The other speaker outputs appear to be matrixed, which means they are mathmaticaly derived from the original two analog channels.
