Hi all, The thing is that I have just bought a 5.1 speaker system to connect to my new Denon 3805, and I have a really stupid doubt: where should I connect the rear speakers?... I have tried on the "Surround A", "Surroond B" and "Surr. Back/Multizone" sections, but althought in the Auto set up the test signal can be heard in all the 5.1 speaker, in the last step I always get the same error message: the system cannot find the speakers either for Surround A or for Surround B.... Therefore, when I play films with 5.1 soundtracks, the rear speakers are silent. I guess I am doing something wrong, but the manual (not a friendly one, IMO) does not help... Pls, can anybody give a clue?? (BTW, this is my first Home Cinema system, so I am sorry if you find that problem stupid...) Thanks all in advance!! Cheers Ps.: Sorry about my poor english (I am writing you from Spain).
