First I just want to say I love my new Denon. But im having a little problem. I have a coax out from my cable box so i can get 5.1 from HBO and utilize DPLII. It works great except for the fact that I get no sound from regular stations like NBC, FOX, CBS. I only get sounds from higher channels, mostly just premium ones. Is this ok? Do I need to run plain ole RCA's also into the receiver and not just the coax??? Also, how do I go about calibrating the Denon? Is there anyway besides bass and treble? Is there an equalizer at all I can mess with? Not to say I dont love the sound, cause I do. But im just curious. Thanks for the input.
