I am curious to know if my receiver is defective or not because, When I'm using DTS Neo:X I enable Front height and Wide with Speaker A-B but I only hear sound out my heights and non from the wides. I have 9.1 Plus FH/FW selected in Speaker Setup and all 11 speakers connected and when I select B only for Wide it works, but no heights. I have also connected a 2-Channel Amplifier to the Heights for Speaker A-B and have just the wides connected to the receiver for 11-channels since it only has 9 amps and still only get heights. It seems like it really is one or the other, but my question is, why would the option for dual Speaker A-B (FH/FW) as an option and it only puts put heights and not wide even with external amplification? It seems like a defect to me, can someone please elaborate or confirm this for me?
