I am trying to disable the center channel in my receiver but i simply can't do it...Even if setting the center channel in "non", the sound is still being reproduced by the center speaker. It´s true that the sound of this channel is bening directed to the front ones, creating a virtual center speaker, but it also continues being reproduced buy the center. Wasnt't the center channel, in these conditions, supposed to eliminated ? Is this ok ? Does it happen to you ? Or my receiver is damaged ? I have to discover it fast, because it is still in warranty.
