I have just bought an 1803 Denon and am starting to feel I wasted my money. I don't have much budget so I only have 2 speakers on it at the moment and RCAs connecting my DSTV (set top satellite tv receiver) and then RCAs to the tv. The sound is muffled and the volume is oscillating as if it thinks it has more speakers and is trying to give surround sound. I have run the setup and switched off the other speakers but it makes no difference. I surround is set to stereo. I don't know what else to do. Also with the muffled sound - I can't get the selector to give me the bass and treble settings. Went according to the manual - the settings simply aren't there. I then tried the "reset" facility - holding the "surround back" and "tone defeat" buttons when switching on. Made no difference either. Where am I going wrong?
