I am currently playing dolby digital 5.1 tracks with the use of four speakers and choosing that I do not have a center channel, a rear surround, or a subwoofer. I have them hooked up through multi-channel direct 1. I understand that I need to hit the multi-channel button once on the front of the reciever to activate the audio. I did this and it worked fine. I watched a film but felt that there was a bit too much treble. I went back to the menu screen and added bass to both the fronts and the surrounds under the equalizer menu. This added the extra punch I was looking for at the moment. However when going back to the equalizer menu everything was grayed out. I have been unable to change the settings again except for one time when they suddenly appeared then went away.... The speakers still play fine. I am just unable to change the settings on them..... How do I make it so that I can go back to the equalizer menu and change the settings? Has anyone else had this problem? Or am I just overlooking something obvious? Thanks for any help!
