Having recently setup my new system with wall mounted PW7 Plasma, 3805, Wharfedale Evo 30's, 575 DVD etc I decided that I would make use of the Bi-Amping feature that can be done on the amp so that Zone 3 is used as a seperate stereo amp for the bass side of the Bi-Wirable speakers and the front-L/R is used as the tweeter side. I did it according to this document : http://www.audioholics.com/productreviews/avhardware/Denon-AVR3805_review04.php All seems well although when I used the Auto Setup, it came back with an error on the front speakers saying they are out of phase. Could this be because of the bi-amping done or could it be true? I am also unable to use the STEREO surround mode or the PURE DIRECT mode as this cuts the bass speakers out. Anyone else configured for 240w each channel and tried auto setup with the same error?
