Hi I have just upgraed today from a Sony 930 to a Denon 3802 amp. I am using 4 Mordaunt short 904's ,1 Mordaunt short 905c and a Mordaunt short 907w subwoofer. I have connected the various leads and I seem to be able to hear distant speech in the subwoofer. I was under the impression that the sub would only deal with sound effects and leave the speech to the centre speaker. I s this ok or have I got something wrong here ? , I did not notice the speech with the 930 amp. Thanks Drphibes *UPDATE* I have the sub connect using the red/white connectors on the denon out 907 in. I unplugged one of these and got no sound , plugged it back in and took the other out and now I have souned effects and no speech in the sub . I cannot remember but am I right in thinking that the sub is a mono channel and therefore only needs a single feed?.
